Question

Why are there three different types of carbon fixation

Answer 1

The correct answer would be "to prevent or minimize photorespiration and water loss".

There are three types of carbon fixation in photosynthesis namely; C₃, C₄, and CAM.

The C₃ plants are the most common plants which do have any specialization in preventing photorespiration.

The C₄ plants are those in which light and dark reactions are separated in different cells. It prevents photorespiration by separating the RuBIsCO in bundle sheath cells.

The CAM plants prevent photorespiration and minimize water loss by separating the light and dark reactions in different time zones, that is, day and night time

Answer 2

In plants, there are three types of carbon fixation during photosynthesis: C3 – a plant that uses the Calvin Cycle for the initial steps that incorporate CO2 into organic matter, forming a 3-carbon compound as the first stable intermediate. Most broadleaf plants and plants in the temperate zones are C3
