Which of the following results from the lactate accumulation in the muscles?
A) It triggers ongoing heavier breathing to provide further oxygen for the muscles.
B) Much of the lactate is transported to the liver, where it is converted to pyruvate.
C) Some lactate converted to pyruvate is converted back to glucose.
D) Some lactate converted to pyruvate is then completely broken down.
E) All of the answer choices are accurate statements about the accumulation of lactate in muscle cells.

Question

Quizplus · Accepted Answer

All the statements accurately describe the physiological responses and metabolic pathways involved when lactate accumulates in the muscles. Lactate accumulation triggers heavier breathing to increase oxygen supply (A), is transported to the liver for conversion to pyruvate (B), can be converted back to glucose in a process known as gluconeogenesis (C), and can be completely broken down in the mitochondria when oxygen is sufficient (D).
