Question

• A. photosynthesis
• B. assimilation
• C. respiration
• D. digestion

Answer 1

Answer: (A), (C)

respiration

Cellular respiration is the process by which cells break down biomolecules, mostly carbohydrates, in the presence or absence of oxygen, to release energy. This energy is stored as ATP and used to power all the cellular processes. Respiration is a catabolic process that results in breakdown of molecules.
Photosynthesis is the process by which plants harness the solar energy to synthesis an organic molecule -glucose, from simple inorganic constituents- carbon dioxide and water. Oxygen is released in this process. Photosynthesis is an anabolic process which result in build up of molecules.
