C₄ plants differ from C₃ plants in

A. Number of ATPs consumed per hexose molecule

B. Type of one product

C. Type of pigments

D. Substrate for CO₂ in carbon assimilation

Answer: Option A

Solution(By Examveda Team)

C₄ plants differ from C₃ plants in the number of ATPs consumed per hexose molecule.
C₄ carbon fixation is one of three known photosynthetic processes of carbon fixation in plants while the C₃ cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms.
Both cycles require ATP for their process, but they differ in the number of ATP required. C₄ plants need 12 ATP's more than C₃ plants to synthesize per hexose molecule.
