Answer #1

Solution

Yes slope is usually expressed as a pure number. Slope is generally defined as amount of rise or vertical distance traversed per unit horizontal distance moved. It is the ratio of vertical distance to horizontal distance. Since in both numerator and denominator we have same dimensional quantity (i.e. length) their ratio is unitless.(Vertical Length / Horizontal Length = unitless number).

In coordinate system we denote vertical rise(or fall ) as y and horizontal as x. So slope can be denoted as :

For e.g. suppose a body moves in a path such that with every 5m horizontal distance covered its height falls by 10 m.

A pure enzyme has a specific activity of 120 units/mg protein. (a) calculate the turnover number if MW=260,000. (b) Calculate the time required for one catalytic cycle The answer for (a) is Turnover = 4.32x10^4 molecules S/(molecules E - min) The answer for (b) is 2.315x10^-5 min per molecule of S converted to P I'm confused over how the answer for (a) was reached. Can you please explain?
