Q1 QUESTION 1 OF 31
Page 1
, True or false: metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life.
CORRECT ANSWER
True
RATIONALE
Metabolism encompasses all biochemical processes that convert food into energy, build cellular components, and eliminate waste, thereby sustaining
homeostasis and supporting life. This intricate network of anabolic and catabolic reactions is essential for growth, reproduction, and response to
environmental changes.
Q2 QUESTION 2 OF 31
True or false: enzymes slow down chemical reactions to conserve energy
CORRECT ANSWER
false, they speed up (catalyze) chemical reactions
RATIONALE
Enzymes function as biological catalysts, lowering the activation energy required for reactions, thereby significantly increasing the reaction rate without
altering the energy balance. This catalytic role is fundamental to metabolic processes, enabling organisms to efficiently manage biochemical reactions.
Q3 QUESTION 3 OF 31
What is catabolism?
CORRECT ANSWER
The process of breaking down larger molecules into useful energy sources
RATIONALE
Catabolism refers to the biochemical process where complex molecules, such as carbohydrates and proteins, are broken down into simpler units,
releasing energy that can be harnessed for cellular functions. This metabolic pathway is essential for maintaining energy balance and supporting
physiological processes.
Q4 QUESTION 4 OF 31
Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell.
CORRECT ANSWER
anabolism
RATIONALE
Anabolism encompasses the metabolic pathways that construct molecules from smaller units, essential for cellular repair and growth following injury.
This process is for synthesizing proteins, nucleic acids, and other macromolecules necessary for restoring cellular function and integrity.
