Fertilisation

HideShow resource information
1) Copulation
Sexual intercourse
1 of 7
2) Capacitation
Occures before fertilsation, Involves removal of choleserol and glycoproteins from membrane above acrosome making it more fluid
2 of 7
3) Acrosome reaction
Release of digestive enzymes from acrosome helping sperm digest pathway through jelly coat to oocyte, Proteins on membrane of sperm and oocyte are complemantary
3 of 7
4) Cortical reaction
Sperm membrane fuses with oocyte causing calcium ions to be released, this triggers vesicles to fuse with the oocyte membrane, Contents of granules released into space between oocyte & jelly coat forming fertilisation membrane to block more sperm
4 of 7
Mitochondria
Produces ATP that provides energy for sperm movement
5 of 7
Flagellum
For sperm mobility, to swim through mucus in cervix
6 of 7
Acrosome
Contains digestive enzymes that are released to digest the jelly coat of the oocyte
