Answer: The energy stored in food molecule (glucose) is released in he process of respiration.
Explanation: Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis: It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A: It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle: It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain: It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
