What role NADPH have in photosynthesis?

Answer 1

NADP is a co enzyme which acts as a hydrogen carrier. The role of NADP is to carry the hydrogen atom from the light dependent stage, which comes from the water molecule ( water molecule splits to form H+ , 2electrons & oxygen, which is a waste gas). NADP carries this hydrogen atom n gets reduced. the reducing power of reduced NADPH reduces the 3 Carbon acid tht has the grp ( -COOH )...to a 3 Carbon sugar that has an aldehyde group ( -CHO ) known as Glyceraldehyde phosphate, which is a triose phosphate. This is the first carbohydrate in photosynthesis. The reason for the conversion of GP to TP is because TP contains more chemical energy.

Answer 2

NADPH is used in catabolic and anabolic reactions within the cell. Reduction and oxidation reactions occur and NADPH is used to dispose of excess reducing equivalents such as electrons. A major source of NADPH is the pentose phosphate pathway. The action of NADPH aids against ROS.

Answer 3

COS THATS THE BOTTOM LINE COS STONE COLD SAID SO!!!!!!

LOL Jokin

NADPH provides a source of hydrogen for reduction reactions in photosynthesis.

In the light independent reactions carbon dioxide is converted into carbohydrate:

CO2 --------> CH2O

NADPH provides the hydrogen needed for this reaction.

Answer 4

it is the hydrogen carrier in the photosynthesis equation.

Answer 5

The light reactions produce ATP and NADPH which they share with the Calvin cycle. The role of the nadph is producing energy.

Answer 6

NADPH is the reducing agent in the Calvin-Benson Cycle.

Answer 7

because its oxidized to form NADP.
