Question

During cellular respiration, the covalent bonds of a molecule are broken down to make products. Which molecule is broken.

Answer 1

During cellular respiration, the primary molecule that is broken down is glucose (C6H12O6). Glucose undergoes a series of chemical reactions, starting with glycolysis, followed by the Krebs cycle (also known as the citric acid cycle), and then oxidative phosphorylation (electron transport chain and chemiosmosis). Throughout these processes, the covalent bonds in glucose are broken, releasing energy that the cell captures to produce ATP (adenosine triphosphate), the main energy currency of the cell.
