Answer:

A. Enzymes lower the activation energy of reactions

Explanation:

Enzymes are biochemical catalyst produced in the body that alter the rate of digestion of food substance.

Like other chemical catalyst, enzymes reduce the activation energy (which is the energy the reactants must attain before being converted to products) in a chemical reaction.

As such, Enzymes lower the activation energy of reactions

Lipophilic hormones function by activating cAMP.
AveGali [126]

Answer:

Option B

Explanation:

Water soluble hormones associate with the G protein of cAMP. This G protein is intra-cellular i.e found inside the cell.  

However in case of lipid derived hormones, the hormone has to diffuse through the cell across the plasma membrane to bind to DNA or the intra-cellular receptors.This regulates the gene transcription and induces protein production that affects the cell functioning for a long time.

Hence, option B is correct

What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?
fgiga [73]

The proteins exhibit four levels of organization:  

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.  

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.  

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.  

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.  

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.
