Fast Block to Polyspermy


Froggy Jumps Fast Block to PolyspermyVersion en ligne Rapid egg membrane depolarization par Ava BENNETT 1 What is the fast block to polyspermy? a Rapid depolarization of the egg plasma membrane b Zona pellucida hardening c Cortical granule exocytosis 2 How soon after sperm–egg fusion does the fast block occur? a Hours b Within milliseconds to a few seconds c Minutes 3 Which ion influx is key to the fast block? a Calcium efflux b Sodium influx causing depolarization c Potassium influx 4 Does the fast block alter the zona pellucida? a Yes, it hardens the zona b It dissolves the zona pellucida c No; that is the slow block 5 What triggers the fast block mechanism? a Cortical granule release b Genome activation c Sperm binding opening Na+ channels 6 Is the fast block a permanent change? a It is not related to depolarization b Yes, permanent c No, a temporary depolarization 7 Which membrane is depolarized during the fast block? a Mitochondrial membrane b Egg plasma membrane c Nuclear envelope 8 What process follows the fast block to ensure polyspermy prevention? a Sperm fusion with more eggs b Slow block via cortical granule exocytosis and zona hardening c Immediate embryo mitosis 9 In which organism is the fast block to polyspermy well characterized? a Mammalian eggs b Sea urchin eggs c Bacterial cells 10 What maintains or returns the egg membrane to its resting potential after the fast block? a Ion channels/pumps restoring the resting potential b Cortical granule release c Zona pellucida hardening 11 Why is fast block needed? a The fast block to polyspermy is required to prevent multiple sperm from fertilizing a single egg b It allows nodes to skip signature verification entirely c It doubles the network's maximum block size automatically
