Question

What enzyme converts ATP to ADP?

Answer 1

Conversion of ATP to ADP:

1. ATP is adenosine triphosphate while ADP is adenosine diphosphate.
2. ATP has three phosphate groups linked by two phosphoanhydride bonds while ADP has two phosphate groups linked by one phosphoanhydride bond.
3. Conversion of ATP to ADP requires needs removal of one phosphate group by breaking one phosphoanhydride bond.
4. The process of breaking phosphoanhydride bonds is known as hydrolysis and energy is released during this process.
5. The class of enzyme that catalyzes this process is known as ATPase.
6. ATPase enzymes are Myosin head, ${\mathrm{Ca}}^{2+}$ ATPase, ${\mathrm{H}}^{+}$ ATPase, etc.
