- Factors affecting the rate of Photosynthesis
- Rate of photosynthesis increases as temperature rises
- Once it reaches its optimum temperature it will
start to decrease if the temperature gets any
higher
- This is called because it is becoming "denatured"
- Rate of photosynthesis increases as the
carbon dioxide concentration increases
- The rate of photosynthesis continues to
increase until it levels off
- Therefore does not denature
- As light intensity increases the rate of
photosynthesis increases
- The rate of photosynthesis continues to
rise until it levels off
- Therefore does not denature
- Respiration
- Is an exothermic reaction
- Aerobic
- Needs oxygen
- Needs glucose
- Makes Carbon dioxide and Water
- Waste products
- More energy released
- Occurs in mitochondria
- word equation
- Glucose + oxygen = carbon dioxide +water
- Anaerobic
- Does not need oxygen
- Makes lactic acid
- Less energy released
- Occurs in cytoplasm
- Word equation
- In humans
- Glucose = Lactic acid
- In fungi and plants
- Glucose = carbon dioxide +ethanol
- Photosynthesis
- What does it?
- Algae
- Phytoplants in leaves
- Some bacteria
- It is an endothermic reaction
- This means that it absorbs energy from its
surroundings
- The equation for photosynthesis is
- carbon dioxide + water = sugar + oxygen
