Enzymatic membrane proteins, known as integral membrane enzymes, catalyze chemical reactions at the membrane's surface or within its lipid bilayer. These proteins facilitate various biochemical processes, such as digestion and signal transduction, by lowering the activation energy of reactions. They often function as receptors or transporters as well, playing critical roles in cellular communication and metabolism.
Receptor proteins.
Transporters, carriers, and enzymes in the plasma membrane are primarily made up of proteins. These proteins can span the membrane, facilitating the movement of substances in and out of the cell, or they can act as enzymes that catalyze biochemical reactions. The specific structure and function of these proteins are determined by their amino acid sequences, which are encoded by the cell's DNA. Additionally, these proteins may interact with lipids and carbohydrates, contributing to their overall functionality in the membrane.
Integral proteins are membrane proteins that are permanently attached to the membrane phospho lipid bilayer.ATPase enzyme is an example for the integral proteins which make ATP. Peripheral proteins in contrast present on the surface of the membrane.

Integral Membrane Proteins control the movement of substances into and out of the Cell (that cannot pass directly through the bi-lipid layer). These are proteins that span the width of the membrane [40 nanometers], and can be channels, pumps, gates of many descriptions, co-transporters, etc. As proteins go, these trans-membrane proteins have internal and external hydrophyllic lengths that have immensely important and varied bio-functions, and the trans-membrane segment is of course hydrophobic.
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside

Enzymes are proteins which speed up chemical reactions.
Enzymes are proteins, which are organic compounds composed of amino acids. These proteins catalyze biochemical reactions in living organisms by lowering the activation energy required for the reactions to occur.
Enzymes are membrane proteins that speed up chemical reactions by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed at a faster rate without being consumed in the process.

Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
