question 15
atp contains ___.
a. glucose
b. alanine

d. tyrosine
e. arginine

Explanation:

ATP (adenosine tri - phosphate) is composed of adenine, ribose, and three phosphate groups. Glucose is a simple sugar, alanine, tyrosine, and arginine are amino acids. None of these (glucose, alanine, tyrosine, arginine) are part of the ATP molecule structure. Phosphate is a key component as seen in the "tri - phosphate" part of ATP's name.

Answer:

C. phosphate
