Answer:

Sucrase will not be able to bind in the active site

A single amino acid substitution—from a polar to the nonpolar amino acid—occurred in the active region of the enzyme as just a result of a mutation within the gene which codes for the enzyme sucrase. Mostly what likely resulted from this mutation. An active site would not allow sucrase to bind.

The connection between the two sugars which comprise sucrose is disrupted when sucrose attaches towards the sucrase active site. The Fructose as well as glucose are released when the connection breaks.

The human body contains sucrase, but where exactly can you find it there?

A partly integrated integral protein called sucrose isomaltase (SI) is found within the small intestine's brush border.
