Biology quiz question helpp!?

Question

Be very specific and explain exactly where the light reactions of photosynthesis occur and where the Calvin cycle of photosynthesis occurs. Then explain what the purpose of the light reactions is and the purpose of the Calvin Cycle.

Answer 1

The light reactions of photosynthesis occur in the part of the cell known as the thylakoids (Stacks of thylakoids are known as grana.). Many chlorophyll molecules are found embedded into the membranes of the thylakoids.

Calvin cycle of photosynthesis takes place in the stroma of chloroplasts in photosynthetic organisms.

The purpose of the light reactions is to convert light energy into chemical energy in the form of ATP & NADPH. ATP & NADPH are energy carriers. They carry energy to the 2nd part of photosynthesis, known as the dark reactions.

The Calvin cycle is a metabolic pathway found in the stroma of the chloroplast in which carbon enters in the form of CO2 and leaves in the form of sugar.

Answer 2

the answer above is pretty detailed.... sounds like an exert from a bio book though. =) nice work

Answer 3

the light reaction occurs in the thylakoid of the mitochondria. the calvin cycle occurs in the stroma of the mitochondria. the purpose of the light reaction is to convert light energy into chemical energy in the form of ATP and NADPH. the purpose of the calvin cycle is to take the energy from photosynthesis 1 and fix carbon.

hope i helped!!!!
