Most people do not have rh antibodies. if an rh negative person receives a transfusion of blood that has rh positive antigens, then the rh negative will form. what is the problem?

An individual that has Rh negative can develop anti-Rh antibodies when exposed to the Rh positive antigen.Rh antibodies are not available in the blood of individuals with no previous exposure to them. Hence if this is the first time for the person to be exposed to the RhD,no immediate danger will occur.

However, after exposure to Rh antigen the person will form antibodies against it thus such a patient can experience severe transfusion reactions if future transfusion with Rh positive blood is done.

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
