Study Notes
Photosynthesis and Cellular Respiration Overview
- Photosynthesis equation: 6CO2 + 6H2O → C6H12O6 + 6O2
- Cellular respiration equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP energy
Similarities and Differences
- Both processes produce energy but function oppositely.
- Photosynthesis assembles glucose from carbon dioxide and water; cellular respiration breaks it down into carbon dioxide and water.
- Similar overall reactions, but they occur in reverse.
Organelles and Processes
- Photosynthesis occurs in chloroplasts; cellular respiration occurs in mitochondria.
- Aerobic respiration requires oxygen, while anaerobic respiration does not.
ATP Importance
- ATP (Adenosine Triphosphate) is essential for energy transfer in cellular activities.
- It is produced during cellular respiration and is critical for metabolic processes.
Cellular Respiration Details
- Cellular respiration is the series of metabolic processes that convert organic substrates into usable energy.
- Purpose: To create energy from glucose.
- Reactants needed: Oxygen and glucose.
- Products of the process: Carbon dioxide, water, and ATP.
Krebs Cycle and Electron Transport Chain
- Krebs Cycle produces two ATP, ten NADH, and two FADH2 molecules.
- The electron transport chain generates the most ATP and happens in the mitochondrial inner membrane.
Fermentation
- Fermentation is an anaerobic process that occurs when oxygen is absent, producing organic acids, gases, or alcohol.
- Common in yeast, bacteria, and muscle cells under oxygen-starved conditions (lactic acid fermentation).
Oxygen's Role
- Breathing oxygen is vital for cellular respiration, enabling cells to produce ATP.
- Lack of oxygen leads cells to switch to anaerobic fermentation for energy production.
