Answer:

The options are

A. secondary structure ... hydrogen bonds

B. secondary structure ... peptide bonds

C. tertiary structure ... hydrogen bonds

D. primary structure ... covalent bonds

E. tertiary structure ... covalent bonds

THE CORRECT ANSWER IS A.

A. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups

-NH and C = O

At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.

The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.

During respirations, select all that apply.
Helen [10]

Answer:

The correct answer will be option- B and C.

Explanation:

The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.

The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.

Thus, Option-B and C is the correct answer.
