Question

a) Glycogen is a highly branched polymer of glucose and is the major storage form of glucose in our bodies. What is the major metabolic advantage of the extensive branching found in glycogen?

b} The standard reduction potentials (Eº’) for the following half-reactions are given below.

    Fumarate + 2H+ + 2e- ? Succinate Eº’ = 0.031 volts     FAD + 2H+ + 2e- ? FADH2 Eº’ = -0.219 volts   If you mixed succinate, fumarate, FAD, and FADH2 together, all at 1.0 M concentrations and pH 7.0 at 25ºC, and added succinate dehydrogenase, what would happen initially (4 points)?

Explanation / Answer

Glycogen are polysaccharides and source of large energy

They are extensively branched advantages of it

1 it gives them more number of terminal residues for its phosphorylation and synthatase

2 make them more soluble

3 it increase rate of glycogen synthesis and degradation
