<span>Out of the following given choices;</span>
a. they are used up in the reactions
b. they lower the overall energy of the reactions
c. they lower the activation energy of the reactions
d. they keep the temperature of the reactions constant
<span>The
answer is C. A catalyst provides an different route for a reaction, mostly
bypassing some transitional states hence lowering the reaction energy. The
catalyst is not consumed in the reaction. </span>
Farming causes a chain reaction: farmers supply crops/meats to distributors, distributors sell crops/meats in bulk to grocery stores, and those in the food industry can obtain their produce through the mentioned grocers. Restaurants rely on grocers, who rely on distributors, who rely on farmers.
<span>Protein tertiary structures
are known to be a three dimensional structure of a protein with a single
polypeptide chain (backbone) and one or more protein secondary structures known as
protein domains.</span>
Tertiary Structure Interactions
1) Hydrophobic Interactions: they are non-
covalent bonds and very important in the formation of tertiary structure.
2) Ionic Bonds: the interaction of both positive
and negative amino acids forms a bond that helps to stabilize the protein molecules.
3) Hydrogen Bonds: this bond exit between the
amino acid with hydrophilic side chain found on the surface of the molecules and
water molecules in a solution.
4) Disulfide Bridges: it is a strong covalent bond commonly found between cysteine residues in close proximity space.
