What are the two main types of respiration?
The two main types of respiration are aerobic respiration, which requires oxygen and produces energy efficiently, and anaerobic respiration, which does not require oxygen and produces energy less efficiently.
Which stage of cellular respiration occurs in cytosol?
Glycolysis is the stage of cellular respiration that occurs in the cytosol. During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH in the process. This stage does not require oxygen and serves as the initial step in both aerobic and anaerobic respiration.
What happens if oxygen is absent during the 2nd stage of cellular respiration?
fermentation will occur.
What is the first stage of cellular respiration and the oldest in terms of evolution?
The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm of cells. This process is thought to be the oldest stage of cellular respiration in evolutionary terms because it is a simple and ancient metabolic pathway that can occur without the presence of oxygen.
Where in respiration does the second stage happen?
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
What stage in cellular respiration is anaerobic?
glycolysis
What is a biochemical pathway of cellular respiration that is anaerobic?
The anaerobic pathway cellular respiration is known as glycolysis. In glycolysis, glucose molecules are broken down into two pyruvate molecules.Glycolysis is the only stage of cellular respiration which can occur without oxygen. The theoretical yield of adenosine triphosphate (ATP) is 2 molecules for this first stage.
Where does the most reactions of aerobic cellular respiration occur?
Glycolysis, the first stage of aerobic respiration, occurs in a cell's cytoplasm. The second stage (acetyl-CoA formation and the Krebs cycle) and the third stage (electron transfer phosphorylation) occur inside a cell's mitochondria. They occur at the inner mitochondrial membrane, which is highly folded. Therefore, most of the reactions of aerobic cellular respiration occur inside the mitochondria of a cell.
What are the two main types of respiration?
The two main types of respiration are aerobic respiration, which requires oxygen and produces energy efficiently, and anaerobic respiration, which does not require oxygen and produces energy less efficiently.
During what stage of the cell cycle does respiration occur?
Cytokinesis
Where in the cell does the second stage of respiration?
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
Which stage of cellular respiration occurs in cytosol?
Glycolysis is the stage of cellular respiration that occurs in the cytosol. During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH in the process. This stage does not require oxygen and serves as the initial step in both aerobic and anaerobic respiration.
How Cellular respiration and fermentation different?
for cellular respiration a process of oxidation takes place at some stage (aerobic) while in fermentation it is in abscence of oxygen(anaerobic)
Which stage of cellular respiration produces the least ATP?
The stage of cellular respiration that produces the least ATP is glycolysis, which occurs in the cytoplasm of the cell. During glycolysis, a net amount of 2 ATP molecules are produced per glucose molecule.
What happens if oxygen is absent during the 2nd stage of cellular respiration?
fermentation will occur.
What is the first stage of cellular respiration and the oldest in terms of evolution?
The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm of cells. This process is thought to be the oldest stage of cellular respiration in evolutionary terms because it is a simple and ancient metabolic pathway that can occur without the presence of oxygen.
Where in the cell do the two stages of respiration occur?
The two stages of respiration, glycolysis and cellular respiration (Krebs cycle and electron transport chain), occur in different parts of the cell. Glycolysis takes place in the cytoplasm, while the Krebs cycle and electron transport chain occur in the mitochondria.
