Question

Describe C₄ pathway with examples.

Answer 1

A C4 plant is a plant that cycles carbon dioxide into four-carbon sugar compounds to enter into the Calvin cycle. These plants are very efficient in hot, dry climates and make a lot of energy. Many foods we eat are C4 plants, like corn, pineapple, and sugar cane.

Answer 2

Answer:

C4 carbon fixation is a photosynthetic mechanism in some plants,

• C4 carbon fixation is used in sugar and other biomolecules is the first step in removing carbon from carbon dioxide. It is one of three known carbon fixing processes.
• Such plants are called C4 plants because a 4-carbon compound (instead of a 3-carbon compound like in C3 or "natural" plants) is the first result of carbon fixation. C4 plants use this 4-carbon compound to concentrate CO2 effectively around rubisco, making it less likely that rubisco will react with O2.
