Cell Membrane Structure And Function Ppt

Cell Membrane - Outer Covering of cell.

Cell membrane structure and function ppt. The folds of the inner membrane are called cristae. Vesicles may combine with plasma membrane to secrete contents Lysosomes Contain digestive enzymes Functions Aid in cell renewal Break down old cell parts Digests invaders Vacuoles Membrane bound storage sacs More common in plants than animals Contents Water Food wastes Mitochondria Break down fuel molecules cellular respiration Glucose Fatty acids Release energy ATP. Made of 2 thin layers of lipid molecules.

1 Isolate cells contents from outside environment 2 Regulate exchange of substances between inside and outside of cell 3 Communicate with other cells Note. Relate cell structures cell membrane nucleus cytoplasm chloroplasts mitochondria to basic cell functions. Functions of the Plasma Membrane selectively isolates the cells contents from the external environment regulates the exchange of essential substances between the cells contents and the external environment allows communication with other cells gives strength shape and protection to the cell.

The Plasma membrane is a thin bi- layered structure which surrounds each cell consists of lipids phospholipids 75 cholesterol 20glycolipids 5 proteins partially or completely embedded carbohydrates etc 6-10 nm thick. Learn the fluid state of membranes and the movement of its lipids and proteins. Selectively Permeable controls the movement of materials into and out of cell.

The cell membrane is a multifaceted membrane that envelopes a cells cytoplasm. W O R K T O G E T H E R Recap Cell parts such as cell membranes are made up of biological molecules. Proteins and lipids are the major components of the cell membrane.
