SPERM MATURATION
Acrosomal vesicle - contains enzymes that digest proteins and complex sugars.
- Important for egg recognition
- Lyses outer covering of egg
Flagellum ñ whip-like structure that propels the sperm using ATP
- ATP is produced by the mitochrondria
- The enzyme dynein hydrolyzes ATP to release energy
- Dynein is attached to the microtubules of the flagellum
Notes:
Absence of dynein: leads to dysfunction of ciliated and flagellated cells including sperm and ciliated respiratory cells (infertility and bronchial infections)
