Question

Explain the process of photosynthesis using light reaction and dark reaction

Answer 1

Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.

Answer 2

Answer:

Light and dark reactions in photosynthesis

Photosynthesis is divided into two parts:

1. Light-dependent reactions (light reactions)

2. Light-independent reactions (dark reactions).

what are light and dark reactions

Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls.

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.
