Study Notes
Photosynthesis
- Photosynthesis is the process by which plants convert carbon dioxide and water into glucose, using energy from sunlight.
- The word equation for photosynthesis is: Carbon dioxide + water → glucose + oxygen.
- The chemical formula for photosynthesis is: 6CO2 + 6H2O → C6H12O6 + 6O2.
- Photosynthesis is an endothermic reaction.
- The rate of photosynthesis is affected by factors like temperature, light intensity, and carbon dioxide concentration.
- As temperature increases, the rate of photosynthesis increases until reaching a maximum point; beyond this, enzymes are denatured and the rate decreases.
- Increasing light intensity increases the rate of photosynthesis up to a point, after which the rate plateaus because another factor is limiting.
- Increasing carbon dioxide concentration increases the rate of photosynthesis until a maximum point, after which the rate plateaus.
- Chlorophyll is essential for photosynthesis; the amount of chlorophyll affects the rate of photosynthesis.
Respiration
- Respiration is an exothermic reaction that releases energy stored in glucose.
- Aerobic respiration requires oxygen and occurs in the mitochondria.
- The word equation for aerobic respiration is: Glucose + oxygen → carbon dioxide + water.
- The chemical equation for aerobic respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O.
- Anaerobic respiration occurs in the absence of oxygen and produces different products depending on the type of organism.
- Muscle cells use anaerobic respiration when oxygen supply does not meet demand; this produces lactic acid.
Factors affecting photosynthesis rate
-
Temperature has a significant impact on photosynthesis rate. Higher temperatures generally enhance the process, but extreme temperatures can impair enzymatic activity.
-
Light intensity, when increased, increases the rate of photosynthesis up to a saturation point.
-
Carbon dioxide concentration, when increased, increases the rate of photosynthesis up to a saturation point.
Other important facts
- The process of respiration is used by organisms to obtain usable energy.
- Organisms need energy for chemical reactions, movement, and warmth.
- Respiration releases energy from glucose.
Plant Cell Structure
- Photosynthesis takes place in chloroplasts, organelles within plant cells.
Macromolecules
- Fats, carbohydrates, and proteins are major food sources broken down for energy and other functions
- Enzymes are crucial in breaking down these macromolecules into smaller units
