Question

What releases energy during respiration in a cell

Answer 1

The main molecule that releases energy during respiration in a cell is adenosine triphosphate (ATP). ATP is the energy currency of the cell and is produced through the metabolic processes of cellular respiration. During respiration, glucose is broken down in a series of enzymatic reactions, such as glycolysis, the citric acid cycle, and oxidative phosphorylation, resulting in the production of ATP and the release of energy.
