Question

Which of the following helps to capture the energy of the sun?

Answer 1

1- A light-dependent reaction

2-A cellular respiration

Answer 2

1. Answer

The process is A. Light dependent reaction.

Explanation:

Among the given list of process in the options, light-dependent reaction traps the solar energy and utilizes it for further metabolic process of the plant.

The light energy trapped form the sun act as source of chemical energy which is required as raw material by the Calvin-cycle.  

The light-needy responses start in a gathering of shade atoms and proteins called a photosystem. Photosystems exist in the layers of thylakoids. A shade particle in the photosystem ingests one photon, at a time and the reaction proceeds.

2. Answer

The reaction is A. Cellular respiration.

Explanation:

In this reaction, the cell breakdown the oxygen and sugar to form ATP from which the energy is released used to metabolic process. This reaction is found in eukaryotic organisms and it involves four stages.

The chemical reaction followed in cellular respiration is:

$\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+6 \mathrm{O}_{2} \rightarrow 6 \mathrm{CO}_{2}+12 \mathrm{H}_{2} \mathrm{O}+36 \mathrm{ATP}$
