Question

Which of the following statements best represents the relationships between the light reactions and the Calvin cycle?

Answer 1

The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the cycle provides water and electrons to the light reactions.


The light reactions supply the Calvin cycle with CO2 to produce sugars, and the Calvin cycle supplies the light reactions with sugars to produce ATP.


There is no relationship between the light reactions and the Calvin cycle.

The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.

The light reactions provide the Calvin cycle with oxygen for electron flow, and the Calvin cycle provides the light reactions with water to split.

I think it is D? @mrdoldum

Answer 3

@mrdoldum I'm not comparing cellular respiration and photosynthesis though, I'm comparing Light reactions and calvin cycle, in a plant.

Answer 4

@Tutormenoq2 In the attachment I covered photosynthesis well enough. I thought, let me read the attachment again.

Answer 5

Ohh I see.

Answer 6

@Tutormenoq2 I think the very first page's diagram should help a bit. Still, what is the output of the light reactions? What is occurring during the light reactions?
