NEET BIOLOGY

Detailed explanation-1: -Carbon from carbon dioxide-inorganic carbon-can be incorporated into organic molecules; this process is called carbon fixation, and the carbon in organic molecules is also known as fixed carbon.

Detailed explanation-2: -This process is called carbon fixation, because CO2 is “fixed” from its inorganic form into organic molecules. ATP and NADPH use their stored energy to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P.

Detailed explanation-3: -Chemosynthesis is defined as the biological production of organic compounds from one-carbon (C-1) compounds and nutrients using the energy generated by the oxidation of inorganic or C-1 organic molecules.

Detailed explanation-4: -Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases. This function is performed by stomata. Water is absorbed by roots from the soil, whether from irrigation or rain.
