3) *Fast block to polyspermy*

This guys is one of the best medical teacher in the whole world !!

YOU ARE LITERALLY THE BEST. It all made sense and the whole explanation was very entertaining and fun to watch. Thank you so much
I have not even completed my schooling but when I see those videos I feel like I am learning true Biology and you are 👍👍👍
Thank you so much! You cleared so much stuff for me! My professor let us go over this part on our own and the book was so confusing! 😁
I would not be able to understand or pass my exams and studies without your videos. Thank you so much you are our hero.
Summary-
Changes in the sperm-
1. Capacitation- alteration in glycoprotein and seminal proteins that coat the spermatozoal head.
Occurs in the uterus
Increases motility
2. Acrosomal reaction- The sperm has specific protein that bind to the zona pellucida receptors ,ZP3. Upon binding, acrosomal head opens releasing acrosin and proteases. This creates a hole in zona pellucida.
3. Fast block to polysperny- As the sperm touches the cell membrane, Na+ influx occurs .
4. Slow block to polyspermy- Smooth ER releases Ca2+ ions which activates lysosome to fuse with the cell membrane of occytes. Hydrolytic enzymes are secreted causing degradation of Zp3 proteins and hardeining of cell membrane.
These lectures are really a huge box of gold to me !!!!! Really awesome thanku so much for such a beautiful , amazing explanation !!!!!!!
