Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-2: -Answer and Explanation: B. Cofactor is not a part of an ATP molecule. ATP stands for adenosine triphosphate where an adenine molecule (a nitrogenous base) is linked to the ribose sugar and the phosphate bonds.

Detailed explanation-3: -Therefore, the statement that is false about ATP is a. It cannot be produced without the presence of oxygen.

Detailed explanation-4: -ATP consists of an adenine attached by the 9-nitrogen atom to the 1′ carbon atom of a sugar (ribose), which in turn is attached at the 5’ carbon atom of the sugar to a triphosphate group.
