What is function of ATP?
The ATP is used for various cellular functions, including transportation of different molecules across cell membranes. Other functions of ATP include supplying the energy required for the muscle contraction, circulation of blood, locomotion and various body movements. A significant role of ATP apart from energy production includes: synthesizing the multi-thousand types of macromolecules that the cell requires for their survival. ATP molecule is also used as a switch to control chemical reactions and to send messages.
