G6pd deficiency is an inherited condition in which the body doesn't have enough of the enzyme glucose-6-phosphate dehydrogenase, or g6pd, which red blood cells (rbcs) function normally. g6pd deficiency is most common in african-american males. many females are carriers. it is known that africa and the mediterranean basin are high-risk areas for the infectious disease malaria. researchers have found evidence that the parasite that causes malaria does not survive well in g6pd-deficient cells. how can you explain this?
