Please, please I do not understand this question for Biochemistry. Can you help me? Steps leading to the correct answer would be helpful!

Under standard conditions, will the following reaction proceed spontaneously as written?

Intermediates of a pathway are shown in the following scheme. Using curved arrows, show the mechanism of each step labeled with a blue letter. Draw out abbreviated structures of the coenzymes, so that you can effectively show all arrow pushing. You may abbreviate the coenzymes by putting R groups on the molecule, but do draw out the parts of the structure that are involved in the arrow pushing. Some of the transformations will require you to show multiple structures to show all of the arrow pushing (particularly some of the coenzyme-mediated steps). You do not need to show specific amino acid residues that perform the catalysis. You can abbreviate acidic amino acid residues “Enz–B–H” and basic residues “B­–Enz”.

Consider the metabolic pathway show below that converts substrate A to B with the enzyme A-ase, B to C with B-ase(I), and so forth. Acety/A-ase Acetate - A-ase Deacetylase A-ase Protease & C-ase B-ase ABCD What is the mechanism of regulation of B-ase? Positive allostery Reversible Covalent modification Isoenzymes Proteolytic Activation Feedback Inhibition 1

What role do low-barrier hydrogen bonds play in serine protease catalysis?
