Question
Chapter 22, Problem 22.75CP
Interpretation Introduction
Interpretation:
The importance of exportation of lactate into the bloodstream during heavy exercise has to be explained.
Concept introduction:
- During heavy muscle exercise, pyruvate from glycolysis is converted to lactate due to the lack of amount of oxygen (anaerobic condition).

What is the relationship between lactate production and lactate removal?
During the initial phase of exercise, muscles can become hypoxic which leads to the buildup of lactate.
a) Fully explain how oxygen shortage can lead to the accumulation of lactate in the muscles.
b) Describe how lactate (often seen as a waste product) can produce glucose via gluconeogenesis.
Does Lactate break down to generate more atp?

For this purpose, new biosensors, applied like a temporary tattoo to the skin, were developed and can alert endurance athletes that they are about to "hit the wall" and will find it difficult to continue exercising. These biosensors monitor lactate present in sweat during strenuous exercise.
