WebJul 11, 2024 · Storing glucose in the liver is not as important as making sure that muscles have enough energy, the heart, the CNS, right? So, because of that hexokinase actually has a higher affinity for glucose (low Km), which means … WebJun 28, 2024 · Glucokinase has a lower Km than Hexokinase so that muscles are able to get the first grab at glucose in the blood. You don't need the liver picking up glucose (and then storing it) unless there is plenty to go around. Muscles get first dibs. There could be other reasons I'm sure, but this is what I was taught.
WebGlucokinase is an isoform of hexokinase with two peculiarities: first, in contrast to hexokinase, the product of its reaction, glucose-6-phosphate, does not inhibit … Web16. How do allosteric effectors influence the apparent value of the equilibrium constant (Kd – dissociation constant of the ligand)? Allosteric activators: decrease (negative = inhibits) cooperativity, decrease affinity, K d increases o Makes the enzyme more suitable for substrate interaction o Shifts equilibrium towards products dissociation
