My level of understanding of these topics before starting this lesson was:

This is a 3-D structure of the Lysozyme protein.

In this diagram which letter represents the active site of the enzyme?

True or False?

Many enzymes require cofactors such as co-enzymes or metals for activity.

My level of understanding of these topics after completing this lesson is:

True or False?

Differences in free energy (∆G) between substrates and products will be inconsistent with reaction equilibrium.

 A “typical” active site of an enzyme:

(There are 3 correct answers)

True or False?

Disulphide bridges between serine side chains are covalent bonds involved in the maintenance of the tertiary structure.

How does an enzyme decrease the activation energy for a reaction?

With four different groups connected to the tetrahedral alpha carbon atom, alpha amino acids are chiral. This means alpha amino acids have two forms which are almost identical but are actually different molecules. Amino acids exist in one or the other of two mirror image forms called the L isomer and D isomer.

Which isomer is used in proteins?

What is the primary structure of a protein?
