For the phrase given below, indicate the type of metabolism referred to, using the following choices:
a. Anabolism only
b. Both anabolism and catabolism (amphibolic)
c. Catabolism only

Is exergonic

검증된 단계별 안내

Understand the definitions of the metabolism types: Anabolism refers to biosynthetic processes that build complex molecules from simpler ones and generally require energy input (endergonic). Catabolism refers to the breakdown of complex molecules into simpler ones, releasing energy (exergonic). Amphibolic pathways involve both anabolic and catabolic reactions.

Analyze the phrase 'Is exergonic' which means the process releases energy. Since catabolic reactions release energy, this phrase is describing a catabolic process.

Recall that anabolic processes are endergonic (require energy), so 'exergonic' cannot describe anabolism only.

Since the phrase does not indicate both building up and breaking down molecules, it does not describe an amphibolic pathway.

Conclude that the metabolism type referred to by 'Is exergonic' is catabolism only.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Catabolism

Catabolism refers to the metabolic pathways that break down molecules into smaller units, releasing energy in the process. These reactions are typically exergonic, meaning they release energy that the cell can use for various functions.

Anabolism

Anabolism involves metabolic pathways that build complex molecules from simpler ones, requiring an input of energy. These reactions are endergonic, meaning they consume energy to synthesize cellular components like proteins and nucleic acids.

Exergonic Reactions

Exergonic reactions release energy as they proceed, often driving cellular processes. In metabolism, catabolic pathways are usually exergonic, providing the energy needed for anabolic reactions and other cellular activities.
