(b) A protein
(c) An enzyme which brings about oxidation
(d) A molecule which contains a High energy bond.

Answer 1

Adenosine triphosphate (ATP) is an organic and hydrotropic compound that generates power for many processes in living cells, e.g. muscle contraction, nerve impulse spreading, condensate dissolution, and chemical synthesis. Present in all known life forms, ATP is sometimes referred to as the "molecular currency unit" of intracellular energy transfer.

Complete Step by Step Answer: Adenosine triphosphate (ATP) is a molecule that contains a High energy bond. ATP may be formed by a variety of distinct cellular processes; the three main pathways in eukaryotes are: - Glycolysis - Citric acid cycle / TCA cycle/oxidative phosphorylation - Beta- oxidation. The overall mechanism of carbon dioxide oxidizes glucose.

Additional Information: Mitochondria is the main source of ATP synthesis in cells during aerobic respiration. Thus, known as the Power- house of the cell. Functions of ATP: - ATP is the primary energy carrier used by all cellular activities. As ATP is hydrolyzed and converted to adenosine diphosphate (ADP), the energy will be released. - ATP is a signaling molecule that is used for cell communication. Kinases, which are enzymes that phosphorylate molecules, use ATP as a source for phosphate groups. - Nucleobase adenine is an element of adenosine, a molecule that is formed by ATP and inserted directly into the RNA.
Note: - When used in metabolic processes, it reduces either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP). Other processes recover ATP so that the human body recycles its body weight equivalent in ATP every day. It is also a source of DNA and RNA and is used as a coenzyme. - The combination of pathways Glycolysis and Citric acid cycle, known as cellular respiration, produces about 30 ATP equivalents per glucose molecule. - Adenine is also present in DNA, and its absorption is very similar, except that ATP is converted to the form of deoxyadenosine triphosphate (dATP) until it becomes part of the DNA chain.
