Which of these is atp?
a molecule consisting of two phosphate groups, ribose, and adenine.
a molecule consisting of three phosphate groups, ribose, and adenine.
a molecule consisting of three phosphate groups, deoxyribose, and adenine.
a molecule consisting of three phosphate groups, ribose, and thymine.
a molecule consisting of three phosphate groups, deoxyribose, and guanine.

The correct answer is A molecule consisting of three phosphate groups, ribose, and adenine.

Explanation:

ATP means adenosine triphosphate, and it is a molecule which has a very important role in energy transfer in the cells.  As its name says, it is composed by:

- adenine: a purine base, which is also a component of nucleic acids.

- ribose: a 5-carbon sugar (in contrast to deoxyribose, ribose has a -OH group in place of a -H group in carbon 2)

- three phosphate groups

Notice that adenine bonded to the ribose is called adenosine.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
