When a mammal respires anaerobically for a long time
- pyruvic acid is convened into acetyl COA
- more energy is released from fats in the body
-
lactic acid accumulates in the muscles
- the Krebs cycle is fully completed.
The correct answer is: C
Explanation
When a mammal respires anaerobically for a long time, lactic acid builds up in the muscles, leading to fatigue and cramps.
- Lactic acid build-up: Anaerobic respiration produces lactic acid as a waste product when glucose is broken down. This lactic acid accumulates in the muscles.
- Muscle fatigue: A buildup of lactic acid causes muscle fatigue.
- pH drop: If too much lactic acid builds up, the pH falls, which can affect enzyme function and lead to fatigue and cramps. The correct answer is option C
