Question

Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?

photoreduction

light-independent reaction

light-dependent reaction

first stage photosynthesis

Answer 1

light-independent reaction

Step-by-step explanation:

Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.

The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:

- Carbon fixation of CO2

- Reduction reactions of G3P

- Regeneration of ribulose 1,5-bisphosphate (RUBP).
