In the C4 pathway, PEP carboxylase captures CO2 efficiently, forming oxaloacetic acid. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Chloroplasts compartmentalize photosynthesis into light harvesting and carbon assimilation stages across membrane systems. Thylakoid membranes, intricate network of flattened discs stacking into grana interconnected by stroma lamellae, house photosystems II and I, cytochrome b6f complex and ATP synthase that convert light energy into ATP and NADPH through non-cyclic and cyclic electron transport, proton pumping and water splitting at oxygen-evolving complex. Those products are consumed in the aqueous phase surrounding thylakoids, the stroma, where the Calvin-Benson-Bassham cycle operates. Stro
