For each of the phrases in questions 1–7, 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

Verified step by step guidance

1. Understand the terms: Anabolism refers to the building up of complex molecules from simpler ones, requiring energy. Catabolism is the breakdown of complex molecules into simpler ones, releasing energy.
2. Identify the term 'exergonic': In biochemical terms, an exergonic reaction is one that releases energy.
3. Relate 'exergonic' to metabolism: Since exergonic reactions release energy, they are typically associated with processes that break down molecules.
4. Determine the type of metabolism: Catabolic processes are characterized by the breakdown of molecules and the release of energy, which aligns with exergonic reactions.
5. Conclude the type of metabolism: Based on the characteristics of exergonic reactions, identify the correct type of metabolism from the given choices.

Key Concepts

Metabolism

Metabolism encompasses all biochemical reactions within a cell, divided into two main categories: anabolism and catabolism. Anabolism refers to the synthesis of complex molecules from simpler ones, requiring energy input, while catabolism involves the breakdown of complex molecules into simpler ones, releasing energy. Understanding these processes is crucial for analyzing how organisms obtain and utilize energy.

Exergonic Reactions

Exergonic reactions are chemical processes that release energy, typically in the form of heat or light. These reactions are characterized by a negative change in free energy, indicating that the products have lower energy than the reactants. In the context of metabolism, exergonic reactions are often associated with catabolic processes, where energy is released as complex molecules are broken down.

Anabolism vs. Catabolism

Anabolism and catabolism are two opposing metabolic pathways. Anabolism builds up molecules and requires energy, while catabolism breaks down molecules and releases energy. The distinction is essential for understanding how cells manage energy resources and maintain homeostasis, as both processes are interconnected and often occur simultaneously in a dynamic balance.
