Biological Membranes definitions Flashcards

Structures composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

Amphipathic molecules forming the bilayer of biological membranes, with hydrophilic heads and hydrophobic tails.

Characteristic of molecules having both hydrophilic and hydrophobic parts, crucial for membrane structure.

Describes molecules or parts of molecules that are attracted to water.

Describes molecules or parts of molecules that repel water.

Describes membranes as fluid structures with proteins and other molecules moving laterally.

Molecules embedded in membranes, making up 20-80% of the mass, with various functions.

Molecule embedded in membranes, contributing to fluidity and stability.

Molecules attached to proteins or lipids on the extracellular surface of membranes.

Two layers of phospholipids forming the basic structure of biological membranes.

Another term for biological membranes, enclosing the cell and its components.

Synonym for biological membranes, surrounding the cell and regulating entry and exit of substances.

Imaging technique used to visualize the structure of biological membranes.

The ability of membrane components to move side-to-side within the bilayer.

Describes the composition of membranes as a mix of various molecules forming a larger structure.
