Question

SHORT ANSWER: Lactase is an enzyme (protein) that breaks down the sugar lactose found in dairy products like cheese and milk. (a) Will this mutation allow the mutated lactase enzyme to function better or worse than the original lactase enzyme(1pt)? (b) Why do you think it will function better/worse

Answer 1

In the case of any enzyme mutation, it is first necessary to evaluate what consequences this mutation would generate, if the consequences aggravate the health of the organism then its mutation is not beneficial, on the contrary, if it would be.

Today it is believed that the human should not take milk after childhood since this stimulates the mutation or overexpression of lactase, which is an enzyme that should not be synthesized throughout the human life.

Step-by-step explanation:

Lactase, a type of β-galactosidase, is an enzyme produced in the small intestine and synthesized during the lactating childhood of all mammals. Its action is essential for the conversion process of lactose, double sugar (disaccharide), into its components glucose and galactose
