Verified step by step guidance
1
Identify the components of an ATP molecule: ATP (adenosine triphosphate) consists of three main parts: adenine, ribose, and three phosphate groups.
Understand the structure of adenine: Adenine is a nitrogenous base, one of the two purine bases found in nucleic acids.
Recognize the sugar component: Ribose is a five-carbon sugar that is part of the backbone of RNA and is present in ATP.
Examine the phosphate groups: ATP contains three phosphate groups, which are linked in a chain and are key to its role in energy transfer.
Compare the given options with the known structure of ATP: Look for the option that includes adenine, ribose, and three phosphate groups to identify the correct answer.
