ATP is used by the mitochondria to break down glucose in respiration. 2. ATP transports molecules against their concentration gradient in the process of active transport. 3. ATP stores energy produced by respira- tion for use by proteins around the cell to do cellular work. correct 4. ATP stores the genetic information of the cell. Explanation: ATP stores energy in the phosphate bonds. It gives energy to proteins to do cellular work when those phosphate bonds are broken, and it is regenerated when mitochondria do cellu- lar respiration. 002 10.0 points Which statement best describes cellular res- piration? 1. It is the release of stored chemical energy in food to produce ATP. correct 2. It is the conversion of light energy into chemical energy. 3.
