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. what is the role of malonic acid with respect to succinate dehydrogenase? a) it is a competitive inhibitor. b) it blocks the binding of fumarate. c) it is a noncompetitive inhibitor. d) it is able to bind to succinate. e) it is an allosteric regulator.

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles

Which of these statements is true about autotrophs, but not heterotrophs? a. they use sugar and oxygen to make carbon dioxide and water.b. they use chlorophyll and oxygen to make carbon dioxide and water.c. they use sunlight, water, and carbon dioxide to make sugars.d. they use sunlight, water, and oxygen to make chlorophyll.
