Question

30. What is ATP? Draw and describe the molecule and how it works. Give a specific example of its action in living things

Answer 1

For doing any sort of work you need energy . When you feel fatigued a glass of glucose water instantly re-energizes you. Similarly for a cell to perform any sort of work say like protein synthesis / active transport of molecules across the plasma membrane it needs energy. The glucose consumed by you contains this energy but the cell cannot use this glucose directly . So to harness the energy stored in a glucose molecule the cell breaks it and stores the energy released by synthesizing an ATP molecule. Thus the energy of a glucose molecule is now present in ATP which the cell can easily make use of. So whenever a cell needs to perform any sort of work it will break the ATP molecule and use the energy released to carry out the respective work.

Regarding the structure you can google it . The energy of an ATP molecule is stored in the two phosphoanhydride bonds. When these bonds are broken energy is released.

specific eg : muscle contraction and relaxation during locomotion. In fact without ATP you wouldn't have typed this question.
