There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
There are 20 (common) amino acids. These are the monomers which form proteins.
A phosphate group and a lipid (to form a phospholipid).
Yes.

The Specificity of Cell Signaling and Coordination of the Response The explanation for the specificity exhibited in cellular responses to signals: different kinds of cells have different collections of proteins. (This is because different kinds of cells turn on different sets of genes). The response of a particular cell depends on its particular collection of signal receptor proteins, relay proteins, and proteins needed to carry out the response. Two cells that respond differently to the same signal differ in one or more of the proteins that handle and respond to the signal. Although cells A, B and C all have the same receptor protein, differences in other proteins account for their differences in responses.
There are 20 different kinds of monomers in proteins, called amino acids.
Proteins are molecules that feed living organisms. There are about twenty different kinds of proteins. Proteins are found in foods.
thousands of different proteins

Lysosomes are structurally and chemically spherical vesicles containing hydrolitic enzymes, which are capable of breaking down virtually all kinds of biomolecules, including proteins, nucleic acids, carbohydrates, lipids, and cellular debris.
