What is difference between glycolipids and glycoproteins

Glycolipids are attached through a glycosidic bond while the glycoproteins are attached by a polypeptide chain

*Glycoproteins are the proteins covalently attached to carbohydrates such as glucose, galactose, lactose, fuctose, sialic acid, N-acetylglucosamine, N-acetylgalactosamine, etc.
_Glycolipids are carbohydrate-attached lipids. Their role is to provide energy and also serve as marker for cellular recognition.
_Glycoproteins and glycolipids act as antennae, receiving chemical messages from other cells. They are also markers & identifiers that identify the cell to other crs for cellular recognition.

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.

The answer is a if u read the definition it makes sense
