How can water affect photosynthesis

A

Shortage can slow or stop the process.

22
Q

How can temperature affect photosynthesis

A

Temperature not within range may damage enzymes and slows down the process.

23
Q

How can the intensity of light affect photosynthesis

A

Increasing light also increases rate of photosynthesis

24
Q

what does the Calvin cycle give to the light dependent reaction?

A

NADP, ADP

25
Q

what does the light dependent reaction give to the light Calvin cycle ?

A

ATP, NADPH
