Which of the following metabolic processes is correctly paired with its definition? A) Fermentation: complete oxidation of glucose to carbon dioxide and water. B) Catabolism: synthesizing cellular constituents from smaller precursors. C) Intermediary metabolism: the coordinated processes of anabolism and catabolism. D) Anabolism: breaking down complex molecules into simpler ones.
Understand the Problem
This question tests your understanding of basic metabolic processes, specifically fermentation, catabolism, intermediary metabolism, and anabolism. You need to identify the option where the process is accurately matched with its definition.
Answer
C) Intermediary metabolism: the coordinated processes of anabolism and catabolism.
The correct answer is C) Intermediary metabolism: the coordinated processes of anabolism and catabolism. Intermediary metabolism encompasses all the biochemical processes that manage energy and metabolites within the cell, including both the synthesis (anabolism) and breakdown (catabolism) of molecules.
Answer for screen readers
The correct answer is C) Intermediary metabolism: the coordinated processes of anabolism and catabolism. Intermediary metabolism encompasses all the biochemical processes that manage energy and metabolites within the cell, including both the synthesis (anabolism) and breakdown (catabolism) of molecules.
More Information
Anabolism involves building complex molecules from simpler ones, requiring energy, while catabolism involves breaking down complex molecules into simpler ones, releasing energy. Fermentation is not a complete oxidation, and the other options have the definitions of anabolism and catabolism swapped.
Tips
A common mistake is confusing anabolism and catabolism. Remember that anabolism 'builds up' and catabolism 'breaks down'.
