What best represents the relationships between the light reactions and the Calvin cycle?

Answer 1

Difference:

The Calvin cycle converts carbon dioxide to carbohydrate.

CO2 --------> (CH2O)

This process requires an energy source and a hydrogen source, as well as carbon dioxide.

The energy source is ATP. The hydrogen source is NADPH.

Both of these substances are produced by the light-dependent reactions.

RELATIONSHIP:

The light reactions and the Calvin cycle are both stages of photosynthesis. The light reactions (photosystems) produce NADPH, ATP, and Oxygen gas. The oxygen is released as a waste product but the NADPH and ATP enter the Calvin cycle, which produces a simple sugar molecule

Answer 2

The products of the light reaction, ATP and NADPH, and used in the Calvin Cycle.

A phosphate from the ATP forms 1,3-bisphosphoglycerate molecules and the electrons from NADPH reduce the 1,3-bisphosphoglycerate molecules into G3P molecules which form glucose when they leave the cycle.

Hope that isn't too confusing!

Answer 3

light is essential in the light dependent reaction for the production of ATP and reduced NADP .these two compounds are utilized for the light independent stage of photosynthesis that occurs at stroma of chloroplast for the conversion of 6C compound glycerol phosphate into 3C compound triose phosphate .

Answer 4

The Greek word photo means light, and photosynthesis uses light in order to make food.

Answer 5

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

Answer 6

Kelvin cycle uses ATP and NADPH produced during light reaction .

Answer 7

The photosystems transfer hydrogen ions and carbon dioxide to the Calvin cycle.
