Answer:
<u>D. Anabolism</u>
Explanation:
<u>Catabolism or catabolic processes</u> involves the <u>breakdown of complex substances into simpler ones.</u> A simple way of remembering catabolic reactions is to think of them as "catastrophic" reactions i.e. reactions in which substances are broken down e.g. breakdown of glucose into carbon dioxide and water.
<u>Absorption</u> is the process by which <u>various substances are absorbed i.e. added into the body</u> e.g. absorption of glucose and fatty acids into the body.
<u>Chemical Digestion</u> it is the process by which<u> various macromolecules are broken down during the process of digestion by body enzymes</u> e.g. breakdown of proteins into amino acids.
<u>Anabolism</u> involves the<u> synthesis of complex substances from simpler ones </u>e.g. synthesis of glucose from carbon dioxide and water.
Coming back to the question,
The formation of glucose (like that occurs in photosynthesis) is an example of anabolism i.e. Option D is the right answer
Breakdown of glucose (like that occurs in respiration) is an example of catabolism.
