1. What effect does very high temperature have on the rate of photosynthesis?

  • More water loss from stomata
  • Greater stress for the plant
  • Active site of rubisco will become denatured so no longer able to accept CO2
  • All of the above
  • Enzymes denature

Other questions in this quiz

2. Why are photosynthetic pigments arranged in a funnel shape?

  • To maximize light absorption and capture as much light as possible
  • To make a photosystem
  • To form an antenna complex.
  • Provide large surface area for electron carriers

3. What causes the light dependent stage to stop because GP cannot be converted into TP?

  • Light
  • Light intensity
  • Amount of light
  • Amount of carbon dioxide
