Question

Q1. For the following diagram depicts the structure of a hypothetical enzyme. The following questions concern this enzyme. A. The structure of this enzyme consists of one regulatory subunit and 3 catalytic subunits (shown to the right). Explain the following graph: FDP ATP Glycerol 20 mM glycerol 0.5 mM FDP Welly M product proper pering of protein I MM substrate

Answer 1

The graph shows the activity of the enzyme.

It shows 3 lines on the graph representing amount catalytic activity of the enzyme at different conditions.

1st line shows increased activity and velocity of product formation in the presence of glycerol. As glycerol interacts with regulatory subunit to regualte enzymatic activity.

2nd line ( in middle) shows velocity of reaction, or ezymatic activity in absence of any regulator

3rd line shows the decreased velocity of reaction/ enzymatic activity due to negative regulator present. This regulator is FDP, which reduces enzyme activity. It's Iowest of the 3 cases here.
