Introduction: The cells growing in the absence of oxygen (anaerobic condition) in which the end product of glycolysis is pyruvate undergoes fermentation. In the process of fermentation, NAD⁺ is regenerated from NADH by transferring electron to organic molecule like lactate and ethanol.

Expert Solution

Explanation of Solution

In the process of fermentation, in anaerobic condition of cell NAD⁺ is regenerated from NADH by transferring electron to organic molecule. To continue the process of glycolysis in the cell, cells need to regenerate NAD⁺. So, without the fermentation process there is no other methodical way to generate NAD^+.In absence of NAD⁺, the glycolysis process is discontinued from the step- 6 that is energy generation phage where the oxidation of glyceraldehydes 3-phosphate produce 1, 3-biphosphoglycerate to continue the glycolysis process.

Introduction: The cells growing in the absence of oxygen (anaerobic condition) in which the end product of glycolysis is pyruvate undergoes fermentation. In the process of fermentation, NAD⁺ is regenerated from NADH by transferring electron to organic molecule like lactate and ethanol.

Expert Solution

Explanation of Solution

In the fermentation process in presence of pyruvate, the NAD⁺ is reinitiated from NADH by transferring electron to organic molecule like lactate and ethanol. To keep glycolysis continuing in the cell, it needs regenerated NAD⁺. There is no suitable way rather than the fermentation to produce NAD⁺. In glycolysis process in absence of regenerated NAD⁺ at energy generation step of glyceraldehyde 3-phosphate to 1, 3-biphosphoglycerate will not occur. The product glyceraldehydes 3-phosphate would accumulate in the cell unable to make either lactate or ethanol, neither it would able to regenerate NAD⁺. So, in this step also glycolysis process is blocked.
