Amino Acids and Proteins

Label the groups on this amino acid. Each colour is a group.

There are 22 amino acids but only [blank_start]20[blank_end] amino acids are encoded by the universal genetic code.

The peptide bond occurs because a [blank_start]carboxyl[blank_end] and an amino acid group form a [blank_start]strong[blank_end] [blank_start]covalent[blank_end] bond releasing water in the process.

Complete this condensation reaction between two amino acids.

Which of these are functions of amino acids?

An enzyme is a globular protein that increases the rate of a biochemical reaction by lowering the [blank_start]activation[blank_end] [blank_start]energy[blank_end] threshold.

The coming together of a substrate molecule and an active site is known as a [blank_start]collision[blank_end].

Drag and drop the labels onto the correct areas of this diagram of how an enzyme works.

The [blank_start]induced[blank_end]-fit model explains how a substrate can induce a conformational change in the active site. Thus allowing the enzyme to [blank_start]catalyse[blank_end] more than one reaction.
