Study Notes
Cellular Respiration Overview
- Aerobic respiration requires oxygen; anaerobic respiration does not.
- Cellular respiration occurs in three primary stages: glycolysis, Krebs Cycle, and the electron transport chain.
- ATP stands for Adenosine Tri-Phosphate, the energy currency of cells.
Processes and Reactions
- The Krebs Cycle is also known as the Citric Acid Cycle and can occur under both aerobic and anaerobic conditions.
- The general formula for cellular respiration:
- 6O2 + C6H12O6 → 6H2O + 6CO2 + 36-38 ATP
- Glycolysis occurs in the cytoplasm, while the electron transport chain takes place in the cristae of mitochondria.
Fermentation
- Alcoholic fermentation converts pyruvate to ethanol in a two-step process, releasing CO2.
- Lactic Acid Fermentation reduces pyruvate to NADH, forming lactate without CO2 release.
- Alcoholic fermentation is utilized in baking and brewing industries.
Energy Production
- Cellular respiration produces significantly more ATP (36-38 ATP) compared to fermentation (2 ATP).
- The electron transport chain yields 32-34 ATP.
- Cellular respiration is critical for energy supply, especially in animals.
Comparative Biology
- Photosynthesis and cellular respiration are interdependent processes with equations that are essentially opposites.
- The reactants of photosynthesis mirror the products of cellular respiration.
Energy Utilization
- Different forms of energy are used during physical activities:
- ATP/PC: used for 10-15 seconds
- Glycolysis: utilized for 50-60 minutes
- Oxidative (fat stores): used after 1 hour or more of exercise.
- During intense exercise, muscles primarily rely on lactic acid fermentation.
Practical Applications
- The presence of sugar increases CO2 production in yeast respiration, as it enhances ATP generation.
- Engaging in over an hour of moderate cardio exercise effectively taps into fat stores, aiding in weight loss.
