svet-max [94.6K]

Answer:

The correct answer will be option-B (purine).

Explanation:

Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.

The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.

Thus, Option-B is the correct answer.

Alina [70]

Answer

D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP

Explanation:

Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.

Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.
