Protein Synthesis

Question 1

What are allosteric enzymes?

Answer 1

Proteins with two different configurations, each with different biological properties.

Question 2

What is the earliest type of protein structure (eg. primary, secondary, tertiary or quaternary) that hydrogen bonding occurs in?

Answer 2

Secondary

Hydrogen bonding makes alpha helices and beta pleated sheets possible.

Covalent bonds are introduced in tertiary structures and quaternary subunits are held together by non-covalent bonds.
