Question

Where do the carbon fixation reactions take place in prokaryotes?

Answer 1

Carbon fixation:

1. In the plant's leaves, sucrose and a variety of other organic compounds are produced via carbon-fixation reactions that start in the chloroplast stroma and continue in the cytosol.
2. The chloroplast found in plant cells is where carbon dioxide is fixed and carbohydrates are created.
3. In the stroma of the chloroplast, enzymatic activities let plants absorb carbon dioxide, which then triggers the creation of sugar molecules.
4. An enzyme known as phosphoenolpyruvate carboxylase adds bicarbonate, which was previously added to the three-carbon acid phosphoenolpyruvate (PEP), as the first step in the carbon-fixation pathway in mesophyll cells.

Location of carbon fixation in prokaryotes:

The Calvin cycle and light-independent reactions, which involves carbon fixation, happen in the stroma.
