Question

Which of the following is true of the light-dependent reactions but not of the light independent reaction

A.also known as the Calvin cycle
B. Requires photons to occur
C. stores energy for long term use
D. Produces carbohydrates
(please include percent of surety in answer)

Answer 1

Correct answer choice is:

B. Requires photons to occur.

Step-by-step explanation:

The light-dependent reactions utilize light energy to produce two molecules required for the following stage of photosynthesis: the energy warehouse molecule ATP and the decreased electron transport NADPH. In plants, the light reactions occur in the thylakoid membranes of organelles termed chloroplasts.

Answer 2

The correct option is B.
The light dependent reaction of photosynthesis requires sunlight energy to occur. When the chlorophyll absorb the sun's energy, electrons inside the plant gains energy as a result of absorbing photons of light from the sunlight. This energy obtained from the sun is then use to make ATP and NADPH molecules.
