Respiration and Photosynthesis Flashcards
What is the role of chlorophyll
Trap light energy
Which useful energy conversion is carried out by chlorophyll?
Light energy to chemical energy
What are the products of a light reaction?
Oxygen and Hydrogen
In photosynthesis, what is ATP required for?
Carbon Fixation
What is Carbon Fixation?
In which cell organelles does carbon fixation occur?
Chloroplasts
Which word equation correctly describes the process of photosynthesis?
Carbon Dioxide + water —> Sugar + oxygen
Which of the following are uses for the sugar produced by photosynthesis?
Two uses for the sugar produced by photosynthesis are making starch and cellulose.
Which of the following are two major limiting factors of photosynthesis?
Carbon dioxide concentration and temperature
Why can photosynthesis not occur at very high temperatures?
Photosynthesis cannot occur at very high temperatures because enzyme activity is lower. Very high temperatures denature the enzymes that control the reactions of photosynthesis.
Which limiting factor of photosynthesis is likely to have the greatest effect on plants growing in an open field during a hot summer day?
Carbon dioxide is the limiting factor of photosynthesis that is likely to have the greatest effect on plants growing in a field on during a hot summer day.
