No amino acid molecule by itself can speed up or catalyze reactions between other molecules; however, when amino acids are joine
Nadya [2.5K]

Answer:

That the enzyme is a protein

Explanation:

Remember the proteins are groups of thousands of amino acids, by their owns, since they are very small units, they can not act as a catalyst.

But as a polymer, the protein enzyme, have different shape, size and physical and chemical properties than a single monomer.

Remember also the proteins to be active, they need certain number of amino acids join together to form a specific shape that is going to match with another molecule to speed the chemical reaction and act as an enzyme.

Place the following substances in order of increasing vapor pressure at a given temperature.
Butoxors [25]

Answer:

NH3 < NF3 < BCl3

Explanation:

The vapour pressure of a substance has something to do with the nature of intermolecular forces between its molecules. If the molecules of a substance are held together by strong intermolecular forces, the substance will display a low vapour pressure at a given temperature and vice versa.

Ammonia has the lowest vapour pressure because of strong intermolecular hydrogen bonds that hold its molecules together.

Photon energy is proportional to which of the following quantities? speed of light in a vacuum frequency of the light emitting t
charle [14.2K]

Answer:

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

Explanation:

Energy of the photon is given by expression:

E=h\times \nu=\frac{hc}{\lambda }

E = Energy associated with the photon

\nu  =  frequency of the light

h = Planck's constant =6.626\times 10^{-34} J s

c = speed of the light in vacuum = constant

\lambda =Wavelength of the photon

E\propto \nu

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.
