Question

please read every question carefully and think about each answer choice before selecting. try to answer without looking at any materials with you the first time and see how you do. take note of what you then study that material again before taking the test a 2nd time. good luck. mr. phillips question 13 where does the energy come from to produce atp? the addition of a phosphate group to atp the breakdown of glucose molecules into other smaller carbon based molecules the conversion of atp to adp the use of chemicals to build up sugars

Explanation:

ATP (adenosine - triphosphate) is produced through cellular respiration. The energy for ATP production comes from the breakdown of glucose molecules in a series of metabolic reactions. When glucose is broken down into smaller carbon - based molecules like pyruvate (in glycolysis) and then further processed in the citric acid cycle and oxidative phosphorylation, energy is released and used to add a phosphate group to ADP (adenosine - diphosphate) to form ATP.

Answer:

the breakdown of glucose molecules into other smaller carbon based molecules
