heamoglobin Flashcards
what is the functio of heamoglobin
transprt oxygen around the body
what type of sturcuture is heamoglobin
quaternary structure
how many polypeptide chanins does heamoglobin have and what do ecah of these contain
4 polypeptide chains and they contain heam groups
what do heam groups have that oxygen binds to in order for it to be trasnported
it has a iron ion
define affinity
ability of heamoglbin to attract/bind to oxygen
define saturation
when heamoglbin is holding the max amount of oxygen it can bind to
define association
binding of oxygen to heamoglbin
define dissociation
oxygen detatches unbinds from heamoglobin
how is oxygen loaded with a high saturation
with a high partial pressure of oxygen
how is oxygen unloaded in a medium saturation
low partial pressure of oxygen
what is cooperative binding
oxgen binding to 1/4 heam group makes the heamoglbin changes shape so its eaier for the other oxyegns to bind
what is the bonr effect
how carbon dioxide effets heamogobins affinity
high CO2 concentration causes the oxygheamoglbin curve to shift to the ______
right
