Question

question 1 (4 points)
(02.05 mc)
what molecule is represented by the molecular model shown below?
a glucose
b adenosine triphosphate (atp)
c adenosine diphosphate (adp)
d starch

Explanation:

To determine the molecule, we analyze the structure:

• Glucose (a) is a monosaccharide with a single 6 - carbon ring, not matching the structure with a pentose, a nitrogenous base, and phosphate groups.
• ATP (b) has three phosphate groups, but the model shows two phosphate groups.
• ADP (c) consists of adenosine (a nitrogenous base - adenine, and a pentose sugar - ribose) and two phosphate groups, which matches the structure (a pentose, a nitrogenous base - like the two - ringed adenine, and two phosphate groups).
• Starch (d) is a polysaccharide, a long chain of glucose units, not matching this structure.

Answer:

c. Adenosine diphosphate (ADP)
