a. Describe how feedback inhibition is used in regulation. Name
2 enzymes in 2 different pathways regulated by feedback
inhibition.
b. What enzymes are responsible for synthesizing and degrading
fructose 2,6-bisphosphate? How is fructose 2,6-bisphosphate used as
a regulatory molecule?
Homework Answers
a.Feed back inhibition is a technique in which the product formed by the enzymatic pathway will it self blocks the activity of the enzyme involved in its biosynthesis.
1.Heme biosynthesis: inhibition of ALA synthase by Heme
2.production of estrogen and progesteron: Inhibition of LH and FSH by estrogen and progesteron by pitutary gland
b.synthesis :phosphofructokinase
Degradation:fructose 2-6 bisphosphatase
Fructose 2-6 bis phosphate elevates the level of PFK1 which is required for the process of glycolysis and it also inhibits the enzyme fructose bisphosphatase which is required for gluconeogenesis there by allows to maintain a balance. So that both glycolysis and gluconeogenesis will not takes place in the same cell there by avoiding futile cycle

please explain answer
Regulation of Lactate dehydrogenase (same enzyme described above). Lactose dehydrogenase (LDH) is a tetramer that can be regulated in several different ways. The crystal structure of the four subunits of lactate dehydrogenase is shown below. In the heart, lactose has a higher affinity for pyruvate than in the skeletal muscle. Analysis of LDH has identified that it is a substrate of FGFR tyrosine kinase, which results in an increase in the production of lactate. Some types of...
