Question 10 • 2026-2027 EDGE Human Anatomy and Physiology A
Emrick is exercising extremely hard, and his cells are working hard to keep up. Eventually, what will happen to his ability to produce energy?
Answer
A
A lack of oxygen will induce fermentation.
B
A lack of oxygen will induce fermentation.
C
A lack of oxygen will halt glycolysis.
D
A lack of oxygen will halt glycolysis.
E
A lack of muscle control will induce fermentation.
F
A lack of muscle control will induce fermentation.
G
A lack of muscle control will halt glycolysis.
H
A lack of muscle control will halt glycolysis.
Explanation
During extremely hard exercise, muscle cells may use oxygen faster than it can be delivered. With too little oxygen for aerobic respiration, muscle cells switch to fermentation, which allows glycolysis to continue producing a small amount of energy. So the correct choice is “A lack of oxygen will induce fermentation.”
