Multiple Choice
In terms of biomolecular class, what type of macromolecule is the enzyme ATP synthase?
A
Polysaccharide (carbohydrate polymer)
B
Protein (a membrane-bound enzyme complex)
C
Triacylglycerol (lipid)
D
Nucleic acid (RNA)
Verified step by step guidance1
Identify the biomolecular classes listed: polysaccharides (carbohydrates), proteins, lipids, and nucleic acids.
Recall that enzymes are biological catalysts, and most enzymes are proteins because proteins have the structural complexity needed for catalytic activity.
Understand that ATP synthase is an enzyme complex embedded in the membrane, which synthesizes ATP during cellular respiration or photosynthesis.
Recognize that ATP synthase is composed primarily of protein subunits, making it a protein macromolecule.
Conclude that among the options given, ATP synthase belongs to the protein class of macromolecules.
