Which of the following are properties of steroid hormones?

I) Steroid hormones are lipid soluble and easily cross the phospholipid bilayer.

II) Steroid hormones usually exert their effects on target cells through membrane receptor proteins.

III) Steroid hormones act on cells close to where they were produced.

IV) Steroid hormones regulate gene transcription by binding to intracellular receptor proteins.

Choose the correct statement

a. Hexokinases IV remains sequesters in the nucleus in case of high F-6-P and high ATP

b. Hexokinases IV remains sequesters in the cytoplasm in case of high F-6-P and high ATP

c. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is not ATP4- but the MgATP2- complex.

d. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.

#Biochemistry

Choose the correct statement of the following

a. In general, high acetyl-CoA or citrate are present, or when a high proportion of the cell’s adenylate is in the form of ATP, gluconeogenesis is favored.

b. When the level of AMP increases, it promotes glycolysis by stimulating PFK-1 by inhibiting FBPase-1

c. Phosphorylation of fructose 6-phosphate, catalysed by phosphofructokinase-2 (PFK-2)

d. Glucagon increases the cellular level of fructose 2,6 bisphosphate, stimulating glycolysis and inhibiting gluconeogenesis.
