Cell transport Flashcards
regulates substances that go in and out of the cell
Cell membrane
3 membrane lipids
Phospholipids
Cholesterol
Glycolipids
2 membrane proteins
Integral proteins
Peripheral proteins
Proteins that adhere to the cell membrane’s surface attached to either side of the cell membrane
Peripheral proteins
Protein that passes all the way through the membrane
Integral proteins
Functions of proteins
Ion channels
Carriers
Receptors
Enzymes
Linkers
Cell identity markers
Ions can flow in and out of cells
Ion channels
Transports polar molecules from one side of the membrane to the other
Carriers
Catalyst for chemical reactions
Enzymes
Cite for cellular recognition
Receptors
Anchor proteins to the cell membrane
Linkers
Enables cells to recognize and respond to foreign cells
Cell identity markers
Linked to glycoproteins and glycolipids
Help in cellular identification
Adhesion for proteins
Carbohydrates
Why cellular transport
Metabolism
Homeostasis
2 types of transport
Passive
Active
3 types of passive transport
Diffusion
Osmosis
Facilitated diffusion
