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 endergonic

검증된 단계별 안내

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

Recall that an endergonic reaction requires an input of energy to proceed, meaning it absorbs energy rather than releasing it.

Since anabolism involves building molecules and requires energy input, it is typically endergonic.

Catabolism, on the other hand, releases energy and is exergonic, so it is not endergonic.

Therefore, when the phrase is 'Is endergonic,' the metabolism type referred to is 'anabolism only.'

주요 개념

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

Endergonic Reactions

Endergonic reactions require an input of energy to proceed because they involve the synthesis of complex molecules from simpler ones. These reactions have a positive Gibbs free energy change and are typically associated with anabolic processes that build cellular components.

Anabolism

Anabolism refers to the set of metabolic pathways that construct molecules from smaller units, consuming energy in the process. It is essential for cell growth and repair, involving biosynthesis of macromolecules like proteins, nucleic acids, and lipids.

Catabolism

Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy stored in chemical bonds. This energy is often captured in ATP and used to drive cellular activities, including anabolic reactions.
