Blastocyst Protease Function During Implantation
Which of the following best describes when and how the blastocyst utilizes proteases?
A
The blastocyst uses proteases to hatch from the zona pellucida upon reaching the uterus, and subsequently uses them to digest the extracellular matrix of the uterine wall to facilitate implantation.
B
The blastocyst uses proteases to degrade proteins, enabling attachment to the wall of the fallopian tube.
C
The blastocyst uses proteases to hatch from the zona pellucida while in the fallopian tube.
D
The blastocyst uses proteases to digest the extracellular matrix of the uterine wall, allowing it to implant.
E
The blastocyst uses proteases to hatch from the zona pellucida upon reaching the uterus.
