where does fertilization occur?
oviduct
_ __ is the joining of a haploid sperm nucleus and a haploid egg nucleus to form
a diploid zygote
fertilization
fertilization is the joining of a _____ sperm and a _____ egg to form a ____ zygote
haploid; haploid; diploid
/ 1/34

_ __ is the final maturation step for the sperm prior to fertilization
capacitation
capacitation is triggered by secretions from the _____
uterine wall
capacitation __ the sperm's plasma membrane and lipids
destabilizes
what are the two main results of capacitation?
acrosomal reaction preparation and increased Ca2+ permeability
what is significant about increased Ca2+ permeability for a sperm after
capacitation?
it causes hyperactivity, making the flagellum beat harder
the ___ is the recognition process between the sperm and the egg before they
fuse together in order to ensure _____
acrosomal reaction; same-species fertilization

the corona radiata is the ___ layer of the egg
outermost
the ___ is a layer of glycoproteins underneath the corona radiata

what does the zona pellucida protein (ZP3) do?
binds to sperm and stimulates the acrosome reaction
an egg's plasma membrane is found underneath the _____
zona pellucida (vitelline layer)
what is the general process of the acrosomal reaction?
sperm --> corona radiata --> zona pellucida --> sperm actin binds ZP3 -->
acrosomal enzyme release --> membrane fusion between sperm and egg -->
fertilization
_ __describes the process where more than one sperm fertilizes an egg
