Question

When there is little to no oxygen available, how do cells release stored energy?

Answer 1

by Cellular respiration

Step-by-step explanation:

Cellular respiration is a place in the cells of organisms to convert chemical energy from oxygen or nutrients into adenosine triphosphate which is the main carrier for energy in cells. so this is how cells release stored energy to the body when there is no oxygen.

Answer 2

Answer: Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP.

or

Fermentation. Some organisms are able to continually convert energy without the presence of oxygen. They undergo glycolysis, followed by the anaerobic process of fermentation to make ATP.
