Question
Chapter 9.2, Problem 2CS
Summary Introduction
To determine: The specific model for predicting the location of amino acid substitution for the prevention of the activation of receptors. The model that has to be labeled such that two Xs are at the place where glutamic acid can be found in the mutant receptor, and one Y should be at the place where no glutamic acid is found.
Introduction: The binding of the ligand with the enzyme-linked receptors is very important for the normal functioning of the cell. The binding of cells results in the activation of the enzyme-linked receptors.

Exercise 5
Membrane receptors are proteins that are incorporated in the cytoplasmic membrane of a cell, allowing the
detection of specific molecules such as (hormones, growth factor) and triggering a cascade of biochemical
Synthesis of protein
reactions.
The adjacent schema represents the steps of
the synthesis of these membrane receptors.
1. Label the structures from a to f.
In order to study the biosynthesis and
secretion of this protein (membrane
receptors), a solution containing radioactive
amino acid was injected in the blood of an
animal. Samples of certain cells were taken
at regular intervals of time. The intensity of
radioactivity was measured in different
cellular organelles.

QUESTION/// Diisopropyl fluorophosphate (DFP) inhibit acetylcholinesterase activity by reacting covalently to a serine residue found within the active site of the enzyme. The physiological effect of this inactivation is interference with neurotransmitter inactivation at the synapses of nerves, resulting in the constant propagation of nerve impulses, which can lead to death.

What is the value of the reverse rate constant k_1 = 1 ×10-4 Incorrect Macmillan Learning You have not correctly calculated the value of the reverse rate constant. To begin, calculate the value of k₁ by dividing the rate of receptor-ligand complex formation (the rate of the forward reaction) by the ligand concentration. k₁ = rate forward [L] Then, calculate the value of the reverse rate constant, k_₁, by multiplying the dissociation constant, Kd, and the forward rate constant, k₁. k_1 = Kak₁arrow_forward
