Consider the following: succinate dehydrogenase catalyzes the conversion of succinate to fumarate. the reaction is inhibited by malonic acid, which resembles succinate but cannot be acted upon by succinate dehydrogenase. increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid. which of the following is correct?
a. succinate dehydrogenase is the enzyme, and fumarate is the substrate.
b. succinate dehydrogenase is the enzyme, and malonic acid is the substrate.
c. succinate is the substrate, and fumarate is the product.
d. fumarate is the product, and malonic acid is a noncompetitive inhibitor.
e. malonic acid is the product, and fumarate is a competitive inhibitor.

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
