HESI A2 Biology Study Guide Questions and Answers Cellular respiration is the process inside of cells that converts nutrients (such as sugars, amino acids, and fatty acids) into ATP (adenosine triphosphate), which is used throughout the organism for energy. Large molecules are broken into smaller molecules, which releases both energy and waste. Aerobic respiration occurs in the presence of Oxygen and has four main stages: • Glycolysis: Larger sugar molecule is broken down into 2 smaller sug...
