When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuo
MatroZZZ [7]

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as <em>Glycolysis</em>.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.
