What are the three main stages of cellular respiration, and where do they occur in the cell?
The three main stages of cellular respiration are:
1. Glycolysis:
* Location: Cytoplasm
* Description: This is the first stage, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.
2. Krebs Cycle (Citric Acid Cycle):
* Location: Mitochondrial matrix
* Description: In this stage, pyruvate is further broken down, releasing carbon dioxide and transferring energy to electron carriers (NADH and FADH2) while producing some ATP.
3. Electron Transport Chain (ETC):
* Location: Inner mitochondrial membrane
* Description: Here, electrons from NADH and FADH2 are transferred through a series of proteins, driving the production of a large amount of ATP through oxidative phosphorylation, with water as a byproduct.
