Describe the relationship between an enzyme, substrate, and active site.
alexdok [17]
So what I know is that enzyme and substrate are like lock and key meaning that when the active site of the enzyme changes, the enzyme will not fit to the substrate which will lead the enzyme to denature. Hope this helps.

Assuming dopant atoms are uniformly distributed in a silicon crystal, how far apart are these atoms when the doping concentratio
enyata [817]

Answer:

d =~ 5.8μm

d =~ 0.13 μm

Explanation:

when the doping concentrations are 5 × 10^15 cm^-3

d = v^-1/3  ; where d represent the distance between the atoms , and v  represent the volume

d =1/ ∛v

d = 1/ ∛5 × 10^15

d = 1/ 170997.5

d = 5.85 × 10 ^ -6

d =~ 5.8μm

when the doping concentrations are 5 × 10^20 cm^-3

d = v^-1/3  ; where d represent the distance between the atoms , and v  represent the volume

d =1/ ∛v

d = 1/ ∛5 × 10^20

using the principle of surds and standard forms, we have

d = 1/ ∛0.5 × 10^21  

d = 1/7937005.26

d = 1.26 × 10 ^ -7

d = 0.126 × 10 ^ -6

d =~ 0.13 μm

Besides the type of unit cell, what information is needed to find the density of a solid consisting of identical atoms?
MAXImum [283]

Besides the type of unit cell, mass and volume are needed to find the density of a solid consisting of identical atoms

The smallest repeating unit with complete crystal structural symmetry is known as a unit cell. A parallelepiped is a name for the unit cell geometry, which provides six lattice parameters as the lengths of the cell edges (a, b, and c) and the angles between them.

The tiniest repeating unit in a crystal lattice is called a unit cell. There are numerous different types of unit cells. One illustration is the cubic crystal system, which consists of three distinct kinds of unit cells: Simple cubic, face-centered cubic, and body-centered cubic are the first three. The simplest repeating unit in a simple cubic structure is the simple cubic unit cell.
