Question

Which is true of the light reaction of photosynthesis? A It produces sugar . B It produces ATP C It breaks down sugar . DIt breaks down ATP .

Answer 1

Answer:B It produces ATP

Explanation: Photosynthetic reactions are divided into the light reactions and the carbon fixation reactions. Light reactions occurs only when plants are exposed to sunlight while the carbon fixation reactions sometimes called the dark reactions are driven by the products of the light reactions.

In light reactions, chlorophyll and other pigments of photosynthetic cells absorb absorb light energy and conserve it as ATP and NADPH with the liberation of oxygen. In carbon fixation reactions, ATP and NADPH produced in the light reactions are used to drive the reduction of carbon dioxide to form sugars.

Equation for the light reactions: H2O + NADP+ + ADP + Pi + solar energy --> ATP + NADPH + O2

Answer 2

Which is true of the light reaction of photosynthesis?

It produces sugar

Step-by-step explanation:

photosynthesis entails when plants make use of carbondioxide, oxygen and light energy in order to produce their food
