A)The shape of the enzyme is important.
B)The shape of the substrate is important.
C)The shape of the active site may be altered by changes in pH.
D)The active site portion of the enzyme is not affected by temperature changes.
E)The active site is a specific sequence of amino acids.
F)Most enzymes are proteins, but a few are lipids.

Question

The active site theory of enzyme functioning states that enzymes use their specific shape to interact with a specific substrate. Therefore, statements A and B are true, as the shape of both the enzyme and substrate are important for proper interaction. Statement C is also true, as changes in pH can alter the shape of the active site and affect enzyme activity. Statement E is also true, as the active site is made up of a specific sequence of amino acids. Statement D is false, as temperature changes can affect the shape and activity of the enzyme's active site. Statement F is also false, as all enzymes are proteins.
