Question

We commonly call ATP the energy currency of the cell. Can you think of some other energy carriers present in a cell? Name any two.

Answer 1

Energy currency of the cell:

Energy currency of the cell are the molecules that provide energy for various metabolic activities by the breakdown of phosphate bonds.
For example: $ATP\to ADP+Pi$

Other energy carriers:

Yes, there are other energy carriers present in a cell such a $NADH$ and $FAD{H}_2$.
After oxidative phosphorylation one $NADH$ and $FAD{H}_2$ molecule produce energy equivalent to $3$ and $2$ ATPs, respectively.

Final answer : $NADH$ , $FAD{H}_2$
