The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes.
In cellular biology, membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes, which are lipid bilayers that contain proteins embedded in them.

Muscular System Meat on the Bones Many advanced animals have muscular systems. You know you do. Did you know that your muscular system is made up of three different types of muscular tissue?
Biology4Kids : Cell Structure: Cell Membrane
Cell Membranes According to cell theory, cells are the main unit of organization in biology. Whether you are a single cell or a blue whale with trillions of cells, you are still made of cells.

Oxidative phosphorylation | Biology (article) | Khan Academy
Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.

Interactive Bacteria Cell Model CELLS alive!
Cytoplasm: This internal "soup" of the bacterial cell is bounded on the outside by the cell envelope. The cytoplasm is mostly water, but within it are the bacterial inclusions nucleoid, plasmids, ribosomes and storage granules as well as the components necessary for bacterial metabolism.
