Detailed explanation-1: -ATP is the main energy source for the majority of cellular functions. This includes the synthesis of macromolecules, including DNA, RNA, and proteins.

Detailed explanation-2: -Answer and Explanation: Adenosine triphosphate is a type of macromolecule known as a nucleic acid. Nucleic acids are long changes of monomers that contain phosphate groups, sugars, and at least one nitrogen atom.

Detailed explanation-3: -RNA – it is made up of ribose sugar, four nitrogenous bases – (adenine, guanine, cytosine, uracil), and one phosphate group. Hence, the structural similarities between the ATP molecule and RNA molecule are due to the presence of ribose sugar, adenine nitrogenous base, and a phosphate group.

Detailed explanation-4: -Carbohydrates are preferred and broken down to synthesize ATP molecules. Glucose is a key carbohydrate that is metabolized via glycolysis and undergoes oxidative phosphorylation to generate ATP molecules.

Detailed explanation-5: -ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis.
