What happens to NADPH and ATP after they are used in the Calvin Cycle?

they recycle back to the light reactions

Which of the following is the correct equation for PHOTOSYNTHESIS?

CO 2 + light + H 2 O --> O 2 + Sugar

CO 2 + sugar + H 2 O --> O 2 + light

O2 + light + H 2 O --> CO 2 + Sugar

CO 2 + O 2 + H 2 O --> Light+ Sugar

What does light do when it strikes the chlorophyll molecules of photosystems I and II?

Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.

Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems.

Light causes the conversion of water into carbon dioxide, oxygen, and electrons.

Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle.

What is the function of NADP+?

It is a light-reflecting pigment

It acts as long-term energy storage

What is the main purpose of the light dependent reactions?

To provide the energy for the calvin cycle

To capture energy and make sugar

carries electrons to the Calvin cycle

The two main stages of photosynthesis are the

light reactions and the Calvin cycle

light reactions and respiration

dark reactions and the Calvin cycle

dark reactions and fermentation

In green plants, the primary function of the Calvin cycle is to

Construct simple sugars from carbon dioxide.
