Study Notes

Photosynthesis

  • Occurs in chloroplasts, specialized organelles in plant cells.
  • Requires three reactants: sunlight, water, and carbon dioxide.
  • Produces two primary products: sugar (glucose) and oxygen.
  • Oxygen, carbon dioxide, water, and glucose are recycled during photosynthesis and cellular respiration.
  • Energy is essential for photosynthesis but is not recycled and must be continuously available.

Cellular Respiration

  • Takes place in mitochondria, specifically within the matrix.
  • Requires two key reactants: oxygen and glucose.
  • Produces three main products: energy (ATP), carbon dioxide, and water.
  • Differentiates between two types of respiration:
    • Aerobic respiration: Requires oxygen, generates up to 38 ATP molecules, and is more energy-efficient.
    • Anaerobic respiration: Does not need oxygen, yields only 2 ATP molecules, and is less energy-efficient.

Glycolysis

  • Initial stage of cellular respiration occurring in the cytoplasm.
  • Produces three main products: four molecules of ATP, two molecules of NADH, and three molecules of pyruvate.
