Question

2b. why does atp production decrease during this shift? (1 pt)
a fermentation produces far less atp per glucose
b more mitochondria become active
c glucose cannot enter the cell

Explanation:

To determine why ATP production decreases, we analyze each option:

• Option A: Fermentation (anaerobic respiration) produces 2 ATP per glucose, while aerobic respiration produces 30 - 32 ATP per glucose. So if there's a shift to fermentation, ATP production drops, which matches the question.
• Option B: More active mitochondria would increase ATP (from aerobic respiration), not decrease it. Eliminate.
• Option C: If glucose couldn't enter the cell, ATP production would decrease, but this is not related to a "shift" (like from aerobic to anaerobic). The question implies a metabolic shift, so A is more relevant.

Answer:

A. Fermentation produces far less ATP per glucose
