What is true about both photosynthesis and cellular respiration? Choose the two correct answers. A. Both use glucose and oxygen to create energy. B. Both involve chemical reactions taking place. C. Both build sugar molecules. D. Both involve the use of energy. E. Both are a catabolic reaction.

D. Both involve the use of energy.

B. Both involve chemical reactions taking place

Explanation:

Photosynthesis utilizes the energy in the photons of sunlight to make ATP by a process called photophosphorylation. Cellular respiration, on the other hand, harnesses the chemical energy in the bonds of the glucose molecule to make ATPs. One major difference between photosynthesis and cellular respiration is the former is an anabolic process while the latter is a catabolic process. All are chemical reaction that observe the thermodynamics law on conservation of matter.

B. Both involve chemical reactions taking place.

D. Both involve the use of energy

Explanation:

Both photosynthesis and cellular respiration are chemical processes. Photosynthesis involves the photolysis of water under ultraviolet radiation from the sun, followed by the formation of glucose and its subsequent polymerization to form starch.

Cellular respiration involves the breakdown of energy molecules in the body using oxygen as the electron acceptor in the process. Both processes involves the use of energy. Photosynthesis requires energy from the sun and cellular respiration requires energy rich molecules such as ATP.
