Which modern day organisms share a common ancestor at node 2?
C, D, and E.
400
Which macromolecule does this picture represent?
nucleotide
400
Number 1 is a substrate. Number 2 is an enzyme before heat treatment. Number 3 is an enzyme after heat treatment. What has happened to the enzyme at number 3?
The enzyme has become denatured and can no longer bind to the substrate.
