Acrosome reaction. Computer artwork showing the process by which an acrosome from a spermatozoon (sperm cell) binds to an ovum (egg cell, bottom). Each spermatozoon has an acrosome in its tip. On reaching the ovum, a reaction occurs that causes the acrosomal process (orange) to push forward through the outer coating of the ovum. Glycoproteins in the vitelline membrane then bind to bindin in the acrosome's membrane and enzymes are released that dissolve the ovum's plasma membrane. This allows the spermatozoon's nucleus to penetrate into and fuse with the ovum's nucleus, causing fertilisation. For the labelled diagram see image 8678.
