Transporters, carriers, and enzymes in the plasma membrane are primarily made up of proteins, which are macromolecules composed of amino acids. These proteins can span the membrane, facilitating the movement of ions and molecules across it, or act as enzymes to catalyze biochemical reactions. Additionally, some of these proteins may be glycosylated, meaning they have carbohydrate groups attached, which can play a role in cell recognition and signaling. Lipids, particularly phospholipids, also contribute to the structural integrity of the plasma membrane but are not directly involved in the functions of transporters and enzymes.
Protein the the cell that moves mechanism. This cell also carries enzymes in the membrane.
Protein is the cell that moves mechanism the depends on movement. This cell carries enzymes in the membrane.

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.
No, insulating organs of the body is not a function of protein macromolecules. Insulation of organs is typically provided by layers of fat tissue in the body. Proteins have diverse functions in the body such as enzymes, transporters, and structural components.

These enzymes are anchored into the cells that make up the brush border as integral membrane proteins. These enzymes are found near the transporters that enable absorption of the digested nutrients.
Yes... In the small intestine, the brush borders of the intestinal lining are the site of terminal carbohydrate digestions. The microvilli that constitute the brush border have enzymes for this final part of digestion anchored into their apical plasma membrane as integral membrane proteins. These enzymes are found near to the transporters that will then allow absorption of the digested nutrients.
Proteins are the macromolecules that serves as enzymes. Meaning all enzymes are proteins (a minor exeption exist as RNA catalyst) and the reverse is not true. Enzymes speed up the biochemical reactions.

Lysosomes contain hydrolytic digestion enzymes. Lysosomes are membrane- bounded vesicles produced by the Golgi apparatus. When lysosomes are fused with macromolecules brought into the cell by vesicle formation at the plasma membrane, then the contents are digested by lysosome enzymes into simpler subunits that then enter the cytoplasm.
They are called integral proteins
ATPase, Na/K channels, hormone receptors, ABC transporters are a few examples. In addition proteins that participate in electron transport chain (in mitochondria) are also membrane proteins that make ATP at the end by ATPase. Nup358 is a membrane protein in nucleus.
it has the digestive enzymes which break down the macromolecules
