As magnesium is highly reactive it reacts with air and forms and coating if magbesium oxide on the surface of ribbon. Therefore in order to remove the layer of the coating of magnesiun oxide, we should rub magnesium ribbon with a sand paper so that we can get the pure product after burning in air..

How is energy stored in the form of ATP?

⭐ ? 5 years, 10 months ago

Yogita Ingle 5 years, 10 months ago

The energy produced during respiration is stored in the form of ATP molecules in the cells of the body and used by the organism as when required.
ADP (Adenosine Di-Phosphate, low energy content), Inorganic Phosphate (Pi) and ATP (Adenosine Tri-Phosphate, high energy content) are the substances present inside a cell.
The energy released during respiration is used to make ATP molecules form ADP and inorganic phosphate.
ADP + Phosphate + Energy → ATP
(Low energy) (For respiration) (High energy)

Thus, energy is stored in the form of ATP.
When the cell needs energy, then ATP can be broken down using water to release energy. Thus:
ATP → ADP + Phosphate + Energy
The energy equivalent to 30.5KJ/mole is released in this process.
ATP is known as energy currency of cells.

2Thank You

⭐ ? 5 years, 10 months ago

ADP molecule reacts with inorganic phosphate,with the help of energy produced in our body in mitochondria to form ATP molecule. When body needs energy ATP breaks down into inorganic phosphate and ADP relasing the energy..
