Question

Please answer question 3

Enzymes are catalysts that facilitate the biochemical reactions that occur within all living organ-
isms. One of the fundamental laws of enzyme kinetics was proposed by Leonor Michaelis and Maud
Menten in 1913. The law has been supported by laboratory experiments and explained through
mathematical modeling. Today Michaelis-Menten kinetics are used in many biological models.
An enzyme molecule is designed to "fit" another molecule called a substrate. The substrate (S)
and enzyme (E) form an intermediate complex (ES), which then dissociates to form the final end-
product of the reaction (P) and the original enzyme (which can be re-used; see figure). An important
question concerns the rate at which product molecules are formed. Under certain assumptions,
Michelis-Menten kinetics relates the rate of production of P to the amount of S present.

1. We let R be the rate of production of the final product P and we let s be the concentration of
the substrate S initially present. Concentrations are measured in units such as micro-moles
(µM), while R is measured in uM/s. (Time is usually measured in seconds.) The Michaelis-
Menten law says that
Vs
R(s)
K + s'
where V > 0 and K > 0 are constants that are specific to each enzyme. Explain why the
units of K and V are µM and µM/s, respectively.
2. Let K = 5 µM and V = 10 µM/s and use Desmos to graph R as a function of s for s > 0.
Describe the increasing/decreasing behavior of your function and its concavity.

3. With general positive values of V and K, compute and simplify R'(s) and use this to confirm
the increasing/decreasing behavior you observed in the graph.
