Ch 6 Metabolism

Front

What is catabolism?

Back

Catabolism is a metabolic pathway that releases energy by breaking down complex molecules into simpler ones, often through exergonic reactions.

Front

What is anabolism?

Back

Anabolism is a metabolic pathway that requires energy to build complex molecules from simpler ones, often through endergonic reactions.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase'.

Front

What is the difference between anabolic and catabolic reactions?

Back

Anabolic reactions build larger molecules from smaller ones and require energy, while catabolic reactions break down larger molecules into smaller ones and release energy.

Front

Give an example of a catabolic reaction.

Back

An example of a catabolic reaction is cellular respiration, where glucose is broken down to produce ATP.

Front

Give an example of an anabolic reaction.

Back

An example of an anabolic reaction is protein synthesis, where amino acids are combined to form proteins.

Front

What is metabolism?

Back

Metabolism is the sum of all chemical reactions that occur within a living organism, including both catabolic and anabolic pathways.

Front

What is an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that releases energy, often associated with catabolic processes.

Front

What is an endergonic reaction?

Back

An endergonic reaction is a chemical reaction that requires energy input, typically associated with anabolic processes.

Front

What role do enzymes play in metabolism?

Back

Enzymes act as catalysts in metabolic reactions, speeding up the rate of reactions without being consumed in the process.
