Question 29

What is the formula for photosynthesis?

Answer 29

6C02+ 6H20 plus sunlight -> glucose +602

Question 30

Where does photosynthesis occur in eukaryotes?

Answer 30

Inside chloroplast with light reaction occurring on thylakoid membranes, and the Calvin cycle occurring in the stroma

Question 31

Where does photosynthesis occur in prokaryotic autotroph?

Answer 31

Chemicals needed for the Calvin Benson cycle are free floating in the cytoplasm and the thylakoids are just unfolding of the plasma membrane
