photosynthesis 3.3

Question 1

what is stage one in photosynthesis

Answer 1

light reactions

Question 2

what happens in light reaction stage

Answer 2

ligfht energy is trapped by chlorophyll and turned into chemical energy, water is split into hydrogen and oxygen. hydrogen moves to stage 2 and oxygen diffuses out of the cell..

Question 3

what happens in carbon fixation

Answer 3

a series of enzyme controlled reactions, which combine hydrogen and ATP with carbon to produce sugar.

Question 4

what are the 3 fates of sugar

Answer 4

respiration, storage in the form of starch and structural in the form of cellulose

Question 5

what are the 3 limiting factors of photosynthesis

Answer 5

light intensity, carbon dioxide concentration and temperature

Question 6
