Question

which of the following contribute to the three - dimensional shape of a protein?
select the correct answer below:
ph of the surroundings
temperature
the amino acid sequence
all of the above
none of the above

Explanation:

• pH of the surroundings: Can disrupt ionic bonds in proteins, affecting their shape.
• Temperature: High temperatures can denature proteins (alter their shape) by breaking hydrogen bonds etc.
• Amino acid sequence: Determines the primary structure, which folds into the 3 - D shape (secondary, tertiary and quaternary structures). So all these factors contribute to a protein's three - dimensional shape.

Answer:

D. All of the above
