your answwer is D
enzymes are made of proteins
a protein's function is determined by their tertiary structure
proteins have a primary, secondary, and tertiary (some even a quaternary) structure
this describes the way the protein is folded
proteins operate within specific temperature and pH ranges
when an enzyme won't operate at 90C it is because its proteins have unfolded
