Study Notes
Cellular Respiration Overview
- Cellular respiration formula: Glucose + Oxygen → Carbon Dioxide + Water + ATP
- Essential process for energy production in cells.
Mitochondria Function
- Krebs cycle and electron transport chain occur in the mitochondria.
- Known as the powerhouse of the cell, facilitating ATP production.
Glycolysis Summary
- First step of cellular respiration known as glycolysis.
- Glycolysis is anaerobic, producing two 3-carbon pyruvates from one 6-carbon glucose.
- Results in a net gain of 2 ATP.
Krebs Cycle Products
- After one glucose undergoes the Krebs cycle, the products are:
- 6 NADH
- 2 ATP
- 4 CO2
- 2 FADH2
Role of NADH and FADH2
- NADH and FADH2 are crucial for the electron transport chain.
- They act as electron carriers, transferring electrons needed for ATP synthesis.
