Question 56

A sperm cell has a streamlined head containing a nucleus and an acrosome, a middle section packed with mitochondria, and a tail.

Which change is most likely if the rate of aerobic respiration in the mitochondria decreases?

[1]
A

The acrosome would store fewer enzymes for breaking down the egg's outer layers

B

The middle section would pass less stored energy to the egg at fertilisation

C

The nucleus would carry fewer chromosomes containing the father's genetic information

D

The tail would move less effectively, reducing movement towards the egg
