Which is true for both photosynthesis and cellular respiration?A.They are simple chemical reactions.
B.They are complex chemical reactions.
C.They require light energy from the sun.
D.They require cells to use water.

Respuesta :

The equation for photosynthesis is carbon dioxide + water + light = sugar + oxygen. The equation for cellular respiration is sugar + oxygen = carbon dioxide + water + released energy. Water is involved in both reactions, but it is a byproduct in respiration. Since chemicals have changed into other chemicals, a chemical reaction is taking place - but it is hard to say whether it is simple or complex.

Both the process photosynthesis and cellular respiration require cells to use water.

Further Explanation:

The photosynthesis process has two stages, that are light-dependent reactions and light-independent reactions. During the light reaction, there occurs the splitting of water that oxidizes the water molecules. During the dark reaction, carbon dioxide fixation is done by plants. It is the reaction wherein the water molecules get oxidized, and carbon dioxide gets reduced. The plants consume carbon dioxide and produce oxygen molecules during the photosynthesis process.  

Cellular respiration is a biochemical pathway during which the breaks down of glucose occurs, and ATP is generated. It is a redox reaction wherein substrates like glucose molecules are oxidized, and other molecules like oxygen are reduced. In anaerobic respiration, glucose is breakdown without oxygen. In the cellular respiration process, animal utilizes oxygen and glucose to produce water and carbon dioxide. Thus, both the process involves water either as a reactant or produces as a byproduct.
