In the presence of oxygen glycolysis is followed by?
Krebs cycle.
Is oxygen necessary for glycolysis?
No - glycolysis is anaerobic (it does occur in the presence of oxygen).
In the presence of oxygen why isn't lactic acid fermentation followed by glycolysis?
In the presence of oxygen, lactic acid fermentation is not followed by glycolysis because cells can switch to aerobic respiration, which is more efficient in generating ATP. This process involves the conversion of pyruvate from glycolysis into acetyl CoA and entry into the citric acid cycle for further ATP production.
Does the Glycolysis require the presence of oxygen?
no
Which step in the process of glycolysis requires the presence of oxygen?
None of the steps in glycolysis require the presence of oxygen. Glycolysis is the process of breaking down glucose to produce energy, and it occurs in the cytoplasm of cells, independent of oxygen availability.
What does it mean to say that glycolysis is an aerobic process?
Glycolysis is not an aerobic process; it is an anaerobic process. Aerobic processes require oxygen, while anaerobic processes do not. Glycolysis breaks down glucose into pyruvate without the need for oxygen.
What effect does the presence of oxygen have on the events that fallow glycolysis?
it helps the electron transport chain
Does glycolysis stop when oxygen becomes unavailable to the cell?
No, glycolysis can still proceed in the absence of oxygen. When oxygen is not available, pyruvate generated by glycolysis is converted into lactate through fermentation to regenerate NAD+ for glycolysis to continue producing ATP.
How much molecular oxygen is required in the fermentation of one molecule of glucose?
In the fermentation of one molecule of glucose, no molecular oxygen is required. Fermentation is an anaerobic process that does not involve oxygen and is used by some organisms to generate energy from glucose in the absence of oxygen.
What process follows glycolysis if oxygen is present?
the Krebs cycle, which is followed by the electron transport chain
What stage of cellular respiration follows glycolysis in the presence of oxygen?
After glycolysis, the next stage of cellular respiration in the presence of oxygen is the citric acid cycle (also known as the Krebs cycle). This cycle takes place in the mitochondria and involves the breakdown of acetyl CoA to produce ATP, carbon dioxide, and high-energy electron carriers.
What are the two terms that are anaerobic chemical reactions?
Fermentation and glycolysis are two examples of anaerobic chemical reactions where energy is produced without the presence of oxygen.
