Question
Chapter 10.4, Problem 4CC
Summary Introduction
To find: To draw the Calvin cycle and find how the number of carbon atoms remains constant after every cycle.
Introduction:
Calvin cycle is a cascade of reactions that cause carbon fixation entered as carbon dioxide (CO2) into the plants. It is also known as the C3 cycle that takes place in the chloroplast of the bundle-sheath cells of the plant leaves.

Photosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process.
CO2 + H2O + Light energy → C6H12O6 + O2

The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which decreases cell carbon dioxide levels, which increases the diffusion gradient. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which immediately becomes a six-carbon sugar that is the base for starch, sucrose, cellulose, etc.arrow_forward
