Asked by: Alison Dare

Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8. Plants have mitochondria and can perform cellular respiration.

In which type of cells does cellular respiration occur?

Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells. It is completed in mitochondria.

What 3 places does cellular respiration occur?

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb’s Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

Which parts of the cell where cellular respiration takes place?

The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

In what part parts does cellular respiration take place in the human cell?

While the digestive, respiratory and circulatory systems play a major role in human respiration, respiration on a cellular level takes place inside the cells and in the mitochondria of the cells.

Do prokaryotes perform cellular respiration?

Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. … The energy currency of these cells is ATP, and one way to view the outcome of cellular respiration is as a production process for ATP.

Why does cellular respiration occur?

Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP (adenosine triphosphate).

Can cellular respiration occur in protists?

Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.

Does cellular respiration occur in both plants and animals or just animals Why?

Cellular respiration occurs in both plant and animals. It is the process by which cells convert ADP (adenosine diphoosphate) into ATP (adenosine triphosphate). Plant and animal cells cannot use ADP as a form of energy. The mitochondria within the cells convert ADP into a useable form of cellular energy: ATP.

Does respiration occur in plants?

Plant cells respire, just as animal cells do. If they stop respiring, they will die. … aerobic respiration uses oxygen and produces carbon dioxide. photosynthesis uses carbon dioxide and produces oxygen.

Why do plants and animals do cellular respiration?

Virtually all cells, including plant cells, go through cellular respiration to break down food to provide the energy needed for normal functioning and growth. … Plants form glucose by photosynthesis and animals get glucose by breaking down the food they eat.

Does cellular respiration only occur in lung cells?

During breathing, termed as external respiration, air from the atmosphere enters into the lungs. … Thus breathing involves intake of oxygen from the atmosphere into the lungs and exit of carbon dioxide from the lungs into the atmosphere. Cellular respiration, also termed as internal respiration, occurs in living cells.

What is needed for cellular respiration to occur?

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Why must cellular respiration occur constantly in cells?

Explanation: Adenosine triphosphate (ATP) produced by cellular respiration must occur constantly. This is because ATP provides energy for cells to carry out their functions. Aerobic cellular respiration uses oxygen as the last electron acceptor of the electron transport chain.

Which type of respiration occurs in prokaryotes?

Certain prokaryotes, including some species of bacteria and Archaea, use anaerobic respiration.

Do eukaryotes use cellular respiration?

Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes.

Do eukaryotic cells perform cellular respiration?

Both eukaryotic and prokaryotic organisms get the energy they need to grow and maintain normal cellular function through cellular respiration. … In eukaryotes, most cellular respiration reactions take place within the mitochondria. In prokaryotes, they occur in the cytoplasm and/or within the cell membrane.

What is cellular respiration in the human body?

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.

Why do plants need respiration process?

Plants also need energy. The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. … Thus, Like other organisms, plants also respire for their survival.

How does respiration occur in plants?

As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration”. In plants, there are two types of respiration: dark respiration and photo respiration.

Does respiration occur only in plants at night?

It is a common misconception that photosynthesis occurs during the day and respiration only happens at night. In fact, respiration in plants occurs all the time – both day and night, as respiration in plants is like breathing in humans.

Does respiration occur in animals?

Cellular respiration occurs in the individual cells. … The cells in both plants and animals perform respiration. Carbon dioxide is also released into the atmosphere when fuels are burned, such as in automobiles or factories. Plants take in carbon dioxide and release oxygen through their leaves.

How do protists do respiration?

They require oxygen for the process of respiration. These types of protists are called obligate aerobes and the respiration occurs in aerobic respiration, while in some cases like parasitic protists they do not require oxygen thus respiration occurs through anaerobic respiration.

Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. … Plants have mitochondria and can perform cellular respiration.

What does cellular respiration do and where does it occur?

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

What 3 places does cellular respiration occur?

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb’s Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

What two places in the cell does cellular respiration occur?

Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion. Figure 1 shows the locations of the main biochemical reactions involved in cellular respiration.

What type of cellular respiration does not require oxygen?

When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP.

What is the main function of cellular respiration?

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

What are the 4 stages of cellular respiration and where do they occur?

The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the …

What is cellular respiration and why is it important?

Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.

Does cellular respiration occur in light or dark?

Cellular respiration can happen in darkness, so the bottles that turned yellow means the organisms went through the process of Cellular respiration. In photosynthesis, carbon dioxide is removed and that is why the water turns blue.

Do plants perform cellular respiration at night?

Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide as follows​1​. Dark – Only respiration takes place. Oxygen is consumed while carbon dioxide is released in plant respiration at night. Dim sunlight – Photosynthesis rate equals respiration rate.

Does cellular respiration take place in humans?

Cellular respiration in humans starts in the digestive and respiratory systems. … The cells use the glucose and oxygen from the circulatory system for energy production. They deliver the waste product, carbon dioxide, back to the red blood cells and the carbon dioxide is released to the atmosphere through the lungs.

How often does cellular respiration occur?

Cells need energy to perform tasks, and therefore respire to perform to break the chemical bonds in ATP , and then use it for energy. So, respiration occurs at all times in the human body, and is essential for survival.

What time does cellular respiration occur?
