Synthesis of complex organic substances from simple inorganic raw materials in the presence of sunlight and chlorophyll is called as ___ which is a ___ process.

Options

A. photosynthesis, anabolic
B. photosynthesis, catabolic
C. respiration, anabolic
D. respiration, catabolic

Answer

A

Explanation

Photosynthesis is an enzyme regulated anabolic process which involves the synthesis of organic compounds, inside the chlorophyll containing cells, from `CO_(2)` and `H_(2)O` with the help of sunlight as a source of energy. Oxygen evolved during photosynthesis comes from water. The equation for photosynthesis can be summarised as follows.
`6CO_(2)+12H_(2) underset("Radiant energy"(686Kcal))overset("Chlorophyll")rarrC_(6)H_(12)O_(6)+6H_(2)O+6O_(2)uparrow`
