What is the main source of potential energy needed for cellular metabolism?

The main source of energy for cell metabolism is in the form ATP or adenosine triphosphate. It a small molecule used in cells as a coenzyme. It transports chemical energy within cells for metabolism. Hope this helps. Have a nice day.

When the ball is rising up, it gains kinetic energy. when the ball reaches the very top, it will have all potential energy, until it falls back down and gains it kinetic energy. finally when you catch the ball or it falls back down, it would have gained its potential energy back.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
