Question

Where in eukaryotic cells does the Calvin cycle take place?

a. thylakoid membrane

b. thylakoid lumen

c. chloroplast stroma

d. granum

Short answer

Within the Chloroplast Stroma, the Calvin cycle takes place. Option (c) Chloroplast Stroma is the correct response.

Step-by-step solution

Introduction

There are two different types of photosynthesis reactions: light-independent reactions and light-dependent reactions. Chlorophyll takes energy from sunshine and turns it into energy via light-dependent processes. This energy, on the other hand, is used to generate sugar molecules from carbon dioxide in light-independent processes.

The light-dependent processes take place in granum, a stack of thylakoids.

The thylakoid membrane contains chlorophyll, which is a photosynthetic pigment that initiates photosynthesis. As a result, the Calvin cycle (light-independent processes) is ruled out in the thylakoid.

Explanation of reason 

Light-independent reactions appear to be uninterested in direct sunshine.

A fluid-filled area in chloroplasts around the stack of thylakoids could possibly be the stroma.

This is the stroma, which is where light-independent processes take place. In eukaryotes, the Calvin cycle takes place in the chloroplast stroma.

As a result, the proper response is c.

 Incorrect Answers  

As a result, options a, b, and d are erroneous.
