Answer:

The special structures in the cell membrane that allow materials such as water and sugar to pass through made of proteins.

Explanation:

Proteins present on the cell membrane known as transmembrane protein. There are 3 main types of membrane proteins are found integral, peripheral and lipid-anchored proteins.

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.

3) Transporter is a type of membrane protein which helping in the movement of molecules across the membrane.

They do not belong in a single column and are separated from the metals by the metalloids. Moreover, the elements are placed in the periodic table in increasing atomic number.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?
quester [9]

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.
