Question

Identify the three components [(i),(ii) and (iii)] of ATP molecule shown in the given figure.

• A. (i)- Ribose; (ii)-Triphosphate group ; (iii)- Adenine
• B. (i)- Adenine ; (ii)- Triphosphate group ; (iii)- Ribose
• C. (i)- Glucose ; (ii)-Triphosphate group ; (iii)- Adenine
• D. (i)- Ribose ; (ii)- Triphosphate group ; (iii)- Guanine

Answer 1

The correct option is A (i)- Ribose; (ii)-Triphosphate group ; (iii)- Adenine

ATP or adenosine triphosphate or Adenine- ribose-phosphate-phosphate-phosphate. The bonds joining the additional phosphate groups o the nucleotides are called high energy or energy-rich bonds.

Adenine- It is a nitrogenous base of 9 membered double ring purine.

Ribose - It is a 5 carbon sugar.

Phosphate- 3 phosphate group attached to the ribose.

ATP acts as a storehouse of as well as a source of energy in a cell.

So, the correct answer is '(i)- Ribose; (ii) -Triphosphate group; (iii)- Adenine'.
