Question

Which of the following technique(s) can be used to study conformational changes in
myoglobin?
P. Mass spectrometry
Q. Fluorescence spectroscopy
R. Circular dichroism spectroscopy
S. Light microscopy
(A) P only (B) P and S only (C) Q and R only (D) S only

Answer 1

Answer:

The correct answer for the required question at hand is the option stated as option A.

According to option A, " P only " scenario applies where P refers to the mass spectrometry.

According to this, there is no other technique which may be used to study the confrontational changes in myoglobin.

Explanation:

Mass spectrometry can be defined as a powerful analytical technique which is known for quantifying well known materials.

It is also used to identify unknown compounds within a sample.

Lastly it may be used for the purpose  to elucidate the structure and chemical properties of different molecules within an experiment.

Answer 2

Answer:

answer is C

Explanation:Fluorescence spectroscopy works on the principle of

fluorescence emission from the sample and is used in

analysing organic compounds. As it works on the

fluorescence, it easily detects changes in the conformation

of a molecule.

Circular dichroism is used to investigate the secondary structure

of proteins, charge transfer transitions and geometric and

electronic structure of a molecule.
