Question

Lactic Acid Fermentation occurs when NADH gives its hydrogen and electrons directly to pyruvate which forms __?

1) Lactate
2) Ethanol
3) Acetyl CoA
4) FADH₂

Answer 1

Lactic Acid Fermentation occurs when NADH transfers hydrogen and electrons to pyruvate, forming lactate and regenerating NAD+ to continue glycolysis.

Step-by-step explanation:

Lactic Acid Fermentation occurs when NADH gives its hydrogen and electrons directly to pyruvate, which forms lactate. This process is crucial because it allows for the regeneration of NAD+, enabling glycolysis to continue and thus additional ATP to be produced. This type of fermentation is carried out by certain bacteria and by muscle cells during intense activity when oxygen is scarce.
