Study Notes
Energy Currency and Cellular Respiration
- ATP (Adenosine Triphosphate) is considered the universal energy currency in biological systems.
Electron Transport Chain
- In eukaryotic cells, the electron transport chain occurs in the mitochondria.
Oxidative Phosphorylation
- The enzyme responsible for catalyzing the conversion of ADP to ATP during oxidative phosphorylation is ATP synthase.
Carbon Dioxide Production
- Carbon dioxide is produced during the citric acid cycle (Krebs cycle) stage of cellular respiration.
Muscle Contraction
- The primary source of energy for muscle contraction during short bursts of intense activity is ATP and phosphocreatine (PCr).
Metabolic Pathways
- Glycolysis is a metabolic pathway that occurs in the cytoplasm and does not require oxygen.
ATP Production
- The net gain of ATP molecules produced from the complete oxidation of one molecule of glucose during cellular respiration is 36-38 ATP.
Krebs Cycle
- Coenzyme A (CoA) is regenerated at the end of the Krebs cycle to continue the cycle.
Anaerobic Conditions
- Under anaerobic conditions in animal cells, the final product of glycolysis is lactate.
Fatty Acid Breakdown
- Beta-oxidation is the process that involves the breakdown of fatty acids to produce acetyl-CoA molecules.
