A molecule of sugar slowly burns in a cell.Compared with the original sugar molecules,the products of these catabolic reactions are ________ and have ________.

Question

Quizplus · Accepted Answer

The products of catabolic reactions are more stable than the original sugar molecules, and they have less energy. This is because during the process of cellular respiration, the sugar molecule is broken down into smaller molecules such as carbon dioxide and water, and the energy released is used to synthesize ATP, the main energy currency of the cell. The energy released during catabolic reactions is not completely lost, but a significant amount is used to fuel the endergonic reactions in the cell. Therefore, the products of catabolic reactions are more stable than the original sugar molecules, and have less energy.
