Answer:

f =  0.0123 × 10²⁰ s⁻¹

Explanation:

Given data:

Wavelength = 244 pm

Frequency = ?

Solution:

First of all we will convert the pm into meter.

244 pm. 1 m / 10¹² pm =  244× 10⁻¹² m

Formula:

f = c/ λ

f = frequency

c = speed of light

λ = wavelength

Now we will put the values in formula.

f = c/ λ

f = 3 × 10⁸ m.s⁻¹ / 244× 10⁻¹² m

f =  0.0123 × 10²⁰ s⁻¹

Predict the effect of adding a non competitive inhibitor to the reaction mixture on the rate of reaction at a high substrate con
Darya [45]

Answer:

A noncompetitive inhibitor can only bind to an enzyme with or without a substrate at several places at a particular point in time

Explanation:

this is because It changes the conformation of an enzyme as well as its active site, which makes the substrate unable to bind to the enzyme effectively so that the efficiency of the enzyme decreases. A noncompetitive inhibitor binds to the enzyme away from the active site, altering/distorting the shape of the enzyme so that even if the substrate can bind, the active site functions less effectively and most of the time also the inhibitor is reversible
