Photosynthesis Flashcards
What happens during Photolysis?
Light energy is trapped by chlorophyll in chloroplasts and converted into chemical energy in the form of ATP.
What is Photosynthesis?
Photosynthesis is a series of enzyme controlled reactions which occur in tow main stages, Photolysis and Carbon Fixation.
During photolysis water is split into what?
Hydrogen and Oxygen.
The hydrogen produced attached to?
A Hydrogen Acceptor and the oxygen diffuses from the cell.
What happens during stage 2?
Carbon fixation and carbon dioxide combines with the hydrogen from photolysis and uses the ATP produced to create the sugar glucose by a series of enzyme controlled reactions.
What are the uses for the glucose produced?
It can be available for respiration, converted into starch for storage or turned into the cell wall component cellulose for a structural use.
What can the carbohydrates produced during photosynthesis be used to produce?
Fats and Proteins.
What are examples of what can limit the rate of photosynthesis?
Carbon dioxide concentration, light intensity and temperature.
