Study Notes
Anaerobic Respiration vs. Fermentation
- Anaerobic respiration uses the electron transport chain, while fermentation does not.
- Fermentation is a process that generates ATP without oxygen or the electron transport chain.
- Fermentation is an extension of glycolysis that enables continuous ATP production via oxidative phosphorylation.
Fermentation Applications
- Both alcohol fermentation and lactic acid fermentation are used by humans for food and industrial production.
Anaerobic Respiration in Prokaryotes
- Anaerobic respiration occurs in certain prokaryotic organisms that inhabit oxygen-deficient environments.
Cellular Respiration and ATP Production
- During cellular respiration, each glucose molecule is broken down into approximately 30 ATP molecules, each containing 7.3 kcal/mol of free energy.
Glycolysis: Sugar Breakdown
- The term "glycolysis" signifies "sugar combining".
- Glycolysis can be divided into three stages: the energy investment phase, the energy payoff phase, and the energy storage phase.
Pyruvate and Energy Storage
- Pyruvate is the ionized form of pyruvic acid.
- A single glucose molecule stores 686 kcal/mol of energy under standard conditions.
