Some common functions of the membrane proteins includes:

1) They are working as ion channels, membrane receptor, G protein couple receptor and many types of transport proteins.

2) Membrane receptor which are present on the cell membrane can pass-on signal between internal and external environment of the cell.

What is the reaction needed to remove a glucose molecule from a polysaccharide, 100 glucose molecues long
vaieri [72.5K]

The reaction needed to remove glucose molecule from a polysaccharide is hydrolysis.

Glucose is a type of monosaccharide which is used in the body for energy.

These monosaccharides such as:

  • Glucose,
  • Fructose and
  • Galactose;

can combine together to form a larger molecule of sugar known as polysaccharides in a reaction called condensation reaction.

Examples of polysaccharides are

  • Chitin
  • Cellulose
  • Start
  • Inulin

These polysaccharides can also be broken down to form the various monosaccharides that makes them up.

The hydrolysis of polysaccharides involves the breaking of the glycosidic bonds that hold the monomers of a polysaccharide molecule together.

This leads to the formation of monosaccharides such as glucose.
