Question

question 2
which statement about sperm structure and function is correct?
sperm have a large number of mitochondria in their midpiece. these mitochondria provide energy for movement of the flagella.
sperm have a large number of mitochondria in their tail. these mitochondria provide energy for movement of the flagella.
sperm have a large number of mitochondria in their head. these mitochondria provide energy for the acrosomal reaction.
sperm have a large number of mitochondria in their head. these mitochondria provide energy for the binding of the sperm and egg.

Explanation:

Sperm structure: head (contains nucleus and acrosome), mid - piece (has mitochondria), tail (flagellum). Mitochondria in mid - piece produce ATP (energy). Flagellum movement (tail) needs energy. Acrosomal reaction (enzymes in acrosome, not energy from mitochondria in head). Binding of sperm and egg (not energy from head mitochondria).

Answer:

Sperm have a large number of mitochondria in their midpiece. These mitochondria provide energy for movement of the flagella.
