00:02 Hello, in this question it has been asked that what is enzyme and the chemical reaction between enzyme and substrate we need to express and we need to express the change in substrate concentration over time concentration of substrate that is s versus time so in the first question that is enzyme is basically act as a biological catalyst in an enzyme substrate reaction it is a globular or big organic proteins so enjamb is a globular big organic proteins it acts as a biological catalyst so in the second question here we need to express a equation for a chemical reaction involving one substrate and one enzyme.

01:59 So enzyme may be characterized by e and substrate characterized by s.

02:14 Substrates are the reactant molecules when enzyme acts as a catalyst over substrate.

02:25 It will express in this type of way.

02:28 First enzyme plus substrate will produce an equilibrium reaction, enzyme substrate complex that is unstable complex so the forward direction red constant may be k1 backward direction red constant k minus 1 and after that these complex enzyme substrate complex that is unstable transition state may decompose and give enzyme plus product so we get our enzyme as this is the proper of catalyst the regeneration of the catalyst after reaction so we get enzyme so it the react constant for these reactions may be expressed as k2 this is the slowest step that is the rate determining step at ds and this is the first step so by this type of equation we can express our enzyme substrate reaction and now the change in substrate concentration over time, that means the rate of this reaction equals to minus d concentration of as divided by dt, that is the time change, can be expressed as k2 multiplied by concentration of enzyme substrate complex.

04:34 Now, we need to apply the steady state approximation that is simply written as as is a for the case of intermediate, that is the enzyme substrate complex...
