Question

cellular processes are carried out by many different types of molecules, mostly proteins. the function of each protein molecule depends on its shape which, in turn, is determined by the proteins specific sequence of ______.
a. monosaccharides
b. nucleotides
c. amino acids
d. triglycerides

Explanation:

To solve this, we analyze each option:

• Option A: Monosaccharides are the building blocks of carbohydrates, not proteins. So A is incorrect.
• Option B: Nucleotides are the building blocks of nucleic acids (like DNA and RNA), not proteins. So B is incorrect.
• Option C: Proteins are polymers made up of amino acids. The specific sequence of amino acids determines the protein's structure (and thus its function). So C is correct.
• Option D: Triglycerides are a type of lipid (fats), not related to protein structure. So D is incorrect.

Answer:

C. amino acids
