The correct option is C Photosynthesis
A biochemical pathway that involves both catabolism and anabolism is termed as amphibolic.
Catabolism is a process in which large molecules are broken down into smaller molecules releasing energy.
Anabolism is a process in which small precursor molecules are converted into complex molecules utilizing energy.
Glycolysis, Krebs cycle and electron transport chain are the various stages of cellular respiration. The different substrates formed during respiration pathway are involved in breaking down as well as formation of substances. Thus, respiration is an amphibolic pathway.
A photochemical process in which the organisms like green plants, certain algae and bacteria, absorb sunlight and use it to convert atmospheric CO2 to carbohydrates in the presence of water is called photosynthesis. Since photosynthesis involves the formation of carbohydrates, it is an anabolic process.
