What gas is used by eukaryotic cells for cellular respiration?
Oxygen is the gas used by eukaryotic cells for cellular respiration. Oxygen is required for the process of oxidative phosphorylation, which is the final stage of cellular respiration where ATP is produced.
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.
What happens if oxygen is absent during the 2nd stage of cellular respiration?
fermentation will occur.
Which is not a stage of cellular respiration is it fermintaion or electron transport?
Fermentation is not considered a stage of cellular respiration as it does not require oxygen. On the other hand, electron transport is a crucial stage of cellular respiration that involves the transfer of electrons through a series of protein complexes in the inner mitochondrial membrane to generate ATP.
What are the first stage of cellular respiration?
The first stage in cellular respiration is known as Glycolysis.
Which of the following is a product of cellular respiration and not fermentation?
ATP is a product of cellular respiration and not fermentation. Fermentation produces lactic acid or ethanol as byproducts, while cellular respiration produces ATP as the main energy currency of the cell.
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)
What is the first stage of all respiration?
The first stage of cellular respiration is called glycolysis. It takes place in the cytoplasm of the cell and needs no oxygen.
What happens if oxygen is absent during the 2nd stage of cellular respiration?
fermentation will occur.
Which is not a stage of cellular respiration is it fermintaion or electron transport?
Fermentation is not considered a stage of cellular respiration as it does not require oxygen. On the other hand, electron transport is a crucial stage of cellular respiration that involves the transfer of electrons through a series of protein complexes in the inner mitochondrial membrane to generate ATP.
What are the first stage of cellular respiration?
The first stage in cellular respiration is known as Glycolysis.
What is the most important stage of cellular respiration?
The most important stage of cellular respiration is the electron transport chain, where the majority of ATP is produced. This stage relies on the transfer of electrons from NADH and FADH2 to generate a proton gradient across the inner mitochondrial membrane, driving ATP synthase to produce ATP.
What is the only stage of cellular respiration that occurs in the cytoplasm?
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.
Respiration releases what amount of energy Large or small?
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
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.
