CELLS 3.1 Cell Membrane Structure- Pre AP Biology Study Notes – New Syllabus.
LEARNING OBJECTIVE
CELLS 3.1(a) Explain how cell membranes function in maintaining dynamic homeostasis for biological systems.
CELLS 3.1(b) Create and/or use models to explain the structure and function of cell membrane components.
Key Concepts:
- CELLS 3.1.1 Cells have phospholipid membranes that are selectively permeable.
a. All cells have membranes that separate the cell from the external environment; some cells also have a cell wall for structure and protection.
b. Membranes consist of a phospholipid bilayer with numerous proteins embedded within and across the surfaces of the membrane.
c. Carbohydrate chains attach to some surface proteins, and together they contribute to cell-to-cell chemical identification.
