The secondary structure of proteins results because of _____ bonding between molecules in the protein molecules' backbone.

topjm [15]

Answer:

Hydrogen bonding

Explanation:

The newly synthesised proteins as a result of the process of translation are linear structures formed by linear arrangement of amino acids.

The linear structure of a protein is known as the primary structure which changes its conformation and take the shape of either the helix or the pleated sheet. This helical or pleated sheet structure is known as a secondary structure.

The secondary structure is formed due to the bond formed between the hydrogen of the carbonyl group and the amino group which form the backbone of the protein structure. The hydrogen bond causes the linear polypeptide to form spiral helical or bend pleated sheet.

Thus, Hydrogen bonding is the correct answer.

Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.
