Why can glycolysis supply energy to cells when oxygen is not avalable?

Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.


What would happen in fermentation if NAD plus is not regenerated?

If NAD+ is not regenerated during fermentation, glycolysis would be blocked as it depends on the continuous regeneration of NAD+ to continue producing ATP. Without NAD+, the conversion of pyruvate into lactate or ethanol would not occur, leading to a buildup of pyruvate and ultimately halting the production of ATP in the absence of oxygen.


What one of these stages occurs in the cytosol of the cell?

Glycolysis occurs in the cytosol of the cell. It is the metabolic pathway that breaks down glucose to produce energy in the form of ATP.


Which of the following reactions ensures that the Calvin cycle can make a continuous supply of glucose?

The regeneration of RuBP (ribulose-1,5-bisphosphate) ensures that the Calvin cycle can make a continuous supply of glucose. This regeneration step allows the cycle to repeatedly fix carbon dioxide and synthesize glucose molecules.

The molecule lactic acid is used as the (temporary) electron acceptor instead of O2.

Glycolysis depends on a continuous supply of what?

Glycolysis depends on a continuous supply of glucose, which is the starting molecule for the pathway. Glucose is broken down into pyruvate through a series of enzymatic reactions in glycolysis to produce ATP and NADH for cellular energy.


Glycolysis depends upon a continuous supply of?

Glycolysis depends upon a continuous supply of glucose molecules as the starting substrate. These glucose molecules are then broken down into pyruvate through a series of enzymatic reactions to produce ATP, a critical source of energy for the cell.

Is wind power a continuous supply?

No, wind power is not a continuous supply of energy as it depends on the availability of wind. Wind speed can vary throughout the day and seasonally, leading to fluctuations in the amount of energy generated by wind turbines.


Does Glycolysis supply energy or store energy?

Glycolysis is the first step in releasing energy from glucose and therefore is supplying energy to the cell.


What conditions enable glycolysis to continue during fermentation?

Fermentation enables glycolysis to continue as long as the glucose supply lasts. Glycolysis enables the fermentation to continues under an anaerobic conditions.

The difference between aerobic and anaerobic glycolysis is?

Aerobic glycolysis requires oxygen to break down glucose into energy, producing a higher yield of ATP. Anaerobic glycolysis does not require oxygen and produces lactate as a byproduct, leading to a lower yield of ATP. Anaerobic glycolysis is used during intense or short-duration activities when oxygen supply is limited.
