erastovalidia [21]

Answer: The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

Explanation:

The energy and frequency are related by :

E=N\times h\times \nu

E = energy of photon

N = number of moles = 1

h = planks constant = 6.6\times 10^{-34}Js

\nu = frequency = 7.5\times 10^{14}Hz

E=1\times 6.6\times 10^{-34}Js\times 7.5\times 10^{14}s^{-1}=49.5\times 10^{-20}J

The energy of a mole of photon associated with this frequency is 49.5\times 10^{-20}J

Explanation:

1. A substrate binds to an enzyme at the active site where the reaction occurs.

2. In a catalyzed reaction, a reactant is often called a  substrate.

3  activity is a measure of how fast an enzyme can convert the reagent to the  product.

4. An inorganic substance necessary for the function of some enzymes is called a cofactor.

5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex.

6. A small organic molecule necessary for the function of some enzymes is  called a  coenzyme.
