a,b,m,o,T and R forms

Question 1

in our context, a and b (phosphorylase):

Answer 1

a = more active form, (without AMP)
b = less active, needs AMP to be in more active of the less acitve possible conformers.

Question 2

m and o

Answer 2

m = modified (did i add a phosphate)

o = original (dephospho)

Question 3

T and R forms

Answer 3

T = tense conformer, less active form

R = relaxed conformer, more active form.

Question 4

phosphorylase a more active form

Answer 4

m-a-R

(modified, a form, R form)

Question 5

phosphorylase b as T form

Answer 5

o-b-T
least active, allosteric control, key in the muscle, if +Pi, is removing the allosteric effectors, unless there is a lot og G+G6P. if this happens, will shift to m-a-R, as the step before is just the placeholder.

Question 6

level of liver GP activity depends on

Answer 6

fraction of “a” form present.
