Question

1) a: draw a pathway called A, with 5 molecules numbered 1 through 5. if the step from 2 to 3 is the rate-determining step, what inermediates will accumulate?

b: if the reaction rate of the rate-determining step is decreased how will the speed with which substance 5 is made change?

Answer 1

In simple chemical kinetics it could be explained as:

     k₁          k₂        k₃         k₄

1-------->2 -------->3 -------->4--------->5

If 2 to 3 is the rate determining step than rate law for this step is

Rate = k₂ [2]

here 2 is accumulating.

if the 4 to 5 is the rate determinig step then rate law for this reaction will be as follows:

Rate = k₄ [4]

here 4 is accumulating

These rate law are incomplete as involve intermediate's. Rate law must have complete reactant or express concentration of intermediate interms of product. If instead of 1, 2 ,3 , 4, 5 we have exact chemical molecules we can get complete rate law of the whole pathway.

It looks like below

Draw a hvpothetical metabolic pathwav Label the diagram by dragging the labels to the appropriate targets k1 k2 из 3 k3 k4 1 2 4 5

Hope this helped you!
