Question

Which metabolic pathway is correctly paired with an example? catabolism – digestion and muscle growth anabolism – photosynthesis and protein synthesis catabolism – photosynthesis and DNA replication

Answer 1

Answer:

Anabolism- photosynthesis and protein synthesis

Explanation:

CATABOLISM:

Catabolism includes metabolic reactions that are responsible for breaking down complex substances into simpler ones. They are "breaking down" reactions.

ANABOLISM:

Anabolism includes metabolic reactions in which complex substances are synthesized from simpler ones. They are "building up" reactions.

⇒An easy way to remember Catabolism is to keep in mind that catabolism includes Catastrophic reactions i.e. complex substances are broken down.

Coming back to the question,

Digestion is a catabolic process in which complex food substances e.g. carbohydrates, proteins are broken down into simpler ones e.g. glucose and amino acids.

Muscle growth, photosynthesis and DNA replication are all anabolic processes as they include synthesis of complex substances.

As only photosynthesis and protein synthesis are correctly matched to anabolism in the question, therefore it is the correct answer.

Answer 2

Anabolism - photosynthesis and protein synthesis
