00:01 Hello.

00:02 So in this question we are given some information like the constant michael's value it is given here as 50 mu -m.

00:18 And also we are given that this reaction volume it is given here for the hexokines.

00:29 It is 90%.

00:31 90 % we can write it as at the 19%.

00:34 By 100 of the maximum of the v max or we can say the maximum reaction.

00:42 So now in this question we need to find out the value of the concentration of the substrate.

00:53 That is the blood glucose.

00:59 So using the michaelis -menton equation, myculeous -menton equation, we know that v -0 is equal to v -max substrate is there and the michaelis constant plus the value of the concentration or for the substrate.

01:27 So put these values which are given in this question to this equation.

01:32 So v -0, we have 90 by 100 for v -max and v -mex.

01:40 Max here and substrate this is in the multiplication form the value of this constant value it is given 50 mu am and plus substrate this is the value that we need to find out so this volume the maximum reaction it will get cancelled so now we have this substrate the concentration here as the 90 by 100 multiply by 50 muam it is there and this whole it will go to the and now it will come here 90 by 100 on multiplying these things to 90 by 100 s is there now on solving this we have we will have 0 to 0 and 0 45 plus this will come 0 this will come 0 .9 s.

02:47 This is mu m...
