Question

Select the correct statement about chemical energy, a term used by biologists to refer to potential energy available for release in a chemical reaction. Light energy is converted to chemical energy during photosynthesis. When a glucose molecule is catabolized to CO2 and H2O, chemical energy is lost. A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.

Answer 1

Answer:

A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.

Explanation:

The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.  

Answer 2

Answer:

Option A , Light energy is converted to chemical energy during photosynthesis.

Explanation:

In the process of photosynthesis, a plant containing chlorophyll converts solar light energy into chemical energy.

The common reaction of photosynthesis is

Carbon dioxide + Water + energy from sun ------> Glucose + carbon dioxide

Thus, energy from sun is used to excite photon with in the thalokoid of plant cell to initiate photosynthesis and then as a result of this process food (glucose containing chemical energy ) and carbon dioxide is formed.

Hence, option A is correct
