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.
