Question

what do u mean by C4 pathway in plants?

Answer 1

C4 pathway of photosynthesis also known as Hatch Slack pathway. This is a process to prevent photorespiration by plants that helps in minimizing the energy loss for the plant.


In \text C_4C
4
​ C, start subscript, 4, end subscript plants, the light-dependent reactions and the Calvin cycle are physically separated, with the light-dependent reactions occurring in the mesophyll cells (spongy tissue in the middle of the leaf) and the Calvin cycle occurring in special cells around the leaf veins. These cells are called bundle-sheath cells.

Answer 2

ant sounds like something that should be associated with Hollywood action movies! However, it is just a type of plant that uses a specific photosynthesis mechanism (C4 photosynthesis) in order to avoid photorespiration. Photorespiration is a wasteful reaction that occurs when plants take in oxygen and give out carbon dioxide instead of taking in carbon dioxide and releasing oxygen.

All plants make energy during theCalvin cycle (the process where plants take up CO2 and turn it into sugar energy); however, in hot, sunny, dry climates, C4 plants are much more efficient than C3 plants (plants that perform C3 photosynthesis - the most common type).

The difference between C3 and C4 plants is that C4 plants make a four-carbon sugar during the Calvin cycle instead of two three-carbon sugars as in C3 plants. This larger sugar in C4 plants brings more CO2 to the RuBisCO enzyme, reducing oxygen levels and making the process energy-intensive. More CO2 is brought into the process because of how cells are located.

C4 plants like very sunny areas with warm temperatures. They can withstand cool evening temperatures.

C4 Photosynthesis Process

To understand what a C4 plant cell is like, we must start from where the CO2 enters the plant.

1. Carbon dioxide comes into the plant via stomata. These are cells that open and close on a leaf for water and gas exchange.

2. The CO2 then enters the mesophyll cells. These are cells that are located toward the surface of a plant leaf and are where photosynthesis typically occurs. However, in C4 plants,
