A vasectomy prevents sperm from entering the male urethra.
<h3>What is Vasectomy?</h3>
- A vasectomy is performed to stop male fertility.
- It assures that after surgery is confirmed to have been successful, the patient will typically be sterile.
- Because vasectomy reversal is expensive and frequently fails to return the male's sperm count or sperm motility to pre vasectomy levels, the surgery is thought of as irreversible.
- Vasectomy has no impact on the prevalence of sexually transmitted illnesses, but those who have had them have an extremely low (almost zero) probability of successfully becoming pregnant again.
- The testes remain in the scrotum after vasectomy, where Leydig cells continue to create testosterone and other male hormones that are released into the bloodstream.
- Sexual desire may be somewhat reduced following a vasectomy, according to certain studies.

Answer:
b. The enzyme and substrate would be stuck together.
Explanation:
Enzymes are proteins whose active site binds to specific chemical reactants (i.e., substrates), thereby forming a complex that is similar to the interaction between a lock and its key. This active complex lowers the energy of the reaction and promotes a conformational change in the substrate to break down it into multiple products. When the enzyme contains mutations in its active site, the ability to bind the substrate is altered. In this case, the enzymatic reaction can't occur because the interaction enzyme-substrate doesn't produce an active complex.
