Practice question
Question
The spectrum of a protein obtained using electrospray ionization mass spectrometry (ESI-MS) is shown below. Two peaks, one at m/z = 2960.6 and the other at m/z = 3552.5, are marked. The mass of the protein associated with the m/z = 2960.6 peak is __________ Da. (Round off to two decimal places) (NAT)
Explanation
The principle of enzyme kinetics explains that substrate binding and catalytic efficiency determine reaction rates. Hence Option NAT fits best because it reflects active-site specificity and regulation, as documented in authoritative sources on biochemistry.
