an atp molecule is made up of 1 ribose molecule, 1 adenine molecule, and 3 phosphate groups joined.
what does the prefix tri - in phosphate mean? ________________________

Explanation:

The prefix "tri - " is a common Latin - derived prefix. In the context of "tri - phosphate" (as in ATP, adenosine tri - phosphate), we can look at its etymology. In Latin, "tri" means three. For example, in words like "triangle" (a three - sided figure), "tricycle" (a three - wheeled vehicle), the prefix "tri - " clearly indicates the number three.

Answer:

The prefix "tri - " means three.
