Compare the efficiency of glycolysis with the efficiency of aerobic respiration

In cellular respiration, oxygen is combined with products fromglycolysis to release energy for the the re-attachment of a phosphate of ATP from ADP and P. Glycolysis provides only enough energy to reattach 2 molecules of ATP where aerobiccellular respiration provides enough energy to reattach 36 molecules.

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
