Question

How is the energy stored in a cell?

Answer 1

Every living being needs the energy to work actively. Energy can’t be created nor be destroyed. So, that energy must be stored in the cell for future use and utilized by the body when it is required. ATP creates a link between anabolism and catabolism and It is the currency of living cells. It is a donor of high-energy phosphate. Its central role in energy metabolism was first explained by Fritz Lipmann and Herman Kalchar.

Complete answer:
Living cells require an input of free energy. Energy is required for the maintenance of highly organized structures, synthesis of cellular components, movement, generation of electrical currents, and many other processes. Cells get free energy from the oxidation of organic compounds that are rich in potential energy. Since all organisms use organic compounds as a source of energy, they must obtain energy-containing organic compounds called food through diet.
Respiration is a metabolic process through which we get free energy which is released from the oxidation of organic compounds and is used in the formation of ATP. The energy released in the cells when the terminal phosphate groups are removed from the structure of ATP which is also called the energy currency of the cell. In the total respiration process, the ATP produced is 36 (an aerobic cell).

Note:
Binding change mechanism is the most widely accepted model for the synthesis of ATP. Paul Boyer developed the binding change, which postulated that ATP synthesis is coupled with a conformational change in the ATP synthase generated by the rotation of the gamma subunit. There are three beta-subunits alternating between three conformational states. They are as follows: O state, L state, and T state.
