A scientist is studying an enzyme that catalyzes the conversion of substrate S to product P following Michaelis-Menten kinetics. She performs an experiment measuring the reaction rate at different substrate concentrations and finds that the enzyme reaches half of its maximum velocity (Vmax⁡) at a substrate concentration of 5 µM.

She then adds a competitive inhibitor at a fixed concentration and repeats the experiment. After analysis, she finds that the enzyme now reaches half of its maximum velocity at a substrate concentration of 15 µM, but the Vmax⁡ remains unchanged.

Which of the following best explains the effect of the competitive inhibitor on the enzyme kinetics?

A) The inhibitor decreases Vmax⁡ by irreversibly binding to the enzyme.

B) The inhibitor increases KM by competing with the substrate for the active site.

C) The inhibitor decreases KM by stabilizing the enzyme-substrate complex.

D) The inhibitor binds to an allosteric site and prevents substrate binding.

B. 

Explanation:

• Competitive inhibitors bind to the active site of the enzyme, competing with the substrate.
• This competition reduces the enzyme's apparent affinity for the substrate, meaning a higher substrate concentration is required to reach half of Vmax⁡V_{\max}Vmax.
• Since KMK_MKM is defined as the substrate concentration at which the reaction reaches half of Vmax⁡V_{\max}Vmax, an increase in KMK_MKM indicates a decreased enzyme affinity for the substrate.
• However, because the inhibitor does not alter the enzyme's ability to convert substrate to product, the Vmax⁡V_{\max}Vmax remains unchanged at high substrate concentrations.
• The experimental result of KMK_MKM increasing from 5 µM to 15 µM, while Vmax⁡V_{\max}Vmax remains the same, is a hallmark of competitive inhibition.

A charged particle with charge qqq and mass mmm is moving with velocity v=(v0,0,0) in a uniform magnetic field B=(0,0,B0).

1. Determine the equation of motion for the particle.
2. Find the radius of the circular motion and the frequency of the particle’s motion in the magnetic field.

• The equation of motion follows uniform circular motion in the xy-plane due to the perpendicular magnetic force.

• The radius of circular motion (Larmor radius) is:

  r=mv0/qB0

• The frequency of motion (cyclotron frequency) is:

  f=qB0/2πm
