Study Notes
Cellular Respiration Overview
- Begins with glucose as the primary substrate for energy production.
Glycolysis
- Glycolysis is the first step in cellular respiration, breaking down glucose.
- It occurs in the cytoplasm of the cell.
- Produces a net gain of 2 ATP molecules.
- Converts glucose into pyruvate, which is a critical intermediate.
Fate of Pyruvate
- Pyruvate can enter anaerobic processes, leading to fermentation.
- Fermentation produces lactic acid in anaerobic conditions.
- Alternatively, pyruvate can be utilized in aerobic respiration pathways.
Krebs Cycle (Citric Acid Cycle)
- The Krebs cycle follows glycolysis, starting with the conversion of pyruvate.
- Occurs in the mitochondrion, the powerhouse of the cell.
- Generates significant electron carriers: 6 NADH, 2 ATP, and 2 FADH2.
Electron Transport Chain
- Electron transport chain occurs in the mitochondrion, utilizing the carriers generated from the Krebs cycle.
- This process results in the production of 34 ATP, contributing to the cell's energy supply.
