Multiple Choice

How many phosphate groups are present in adenosine diphosphate (ADP)?

Previous problemNext problem

Verified step by step guidance

Understand the structure of adenosine diphosphate (ADP). ADP is a nucleotide composed of three main components: an adenine base, a ribose sugar, and two phosphate groups attached to the ribose.

Recall the naming convention for ADP. The term 'diphosphate' indicates the presence of two phosphate groups. 'Di-' is a prefix meaning two.

Visualize or draw the molecular structure of ADP. This can help confirm the presence of two phosphate groups attached to the ribose sugar.

Compare ADP to other related molecules, such as adenosine triphosphate (ATP), which has three phosphate groups, and adenosine monophosphate (AMP), which has one phosphate group. This comparison reinforces the understanding of the number of phosphate groups in ADP.

Conclude that ADP contains exactly two phosphate groups based on its structure and naming convention.
