Question

10 - assignment 2 - term1 (2025 - 2026) (10b3 - bio)

1. how do different r groups in amino acids affect protein folding and function?

(1 point) *

a) they have no effect on protein shape
b) they cause proteins to fold differently due to varied chemical properties
c) they form peptide bonds between amino acids
d) they control how fast proteins are made

Explanation:

Amino acid R - groups have diverse chemical properties (e.g., hydrophobic, hydrophilic, charged). These properties influence interactions (e.g., hydrogen bonds, hydrophobic interactions) during protein folding. Different R - group properties lead to different folding patterns, which in turn affect the protein's three - dimensional shape and, consequently, its function.

• Option a is incorrect because R - groups do affect protein shape.
• Option c is incorrect as peptide bonds are formed between the amino and carboxyl groups (not R - groups) of amino acids.
• Option d is incorrect as R - groups do not control the rate of protein synthesis.

Answer:

B. They cause proteins to fold differently due to varied chemical properties
