Types of transport
Passive transport requires no energy.
Types of passive transport include simple diffusion, osmosis, and facilitated diffusion.
Osmosis: movement of a solvent
Active transport requires energy from the cell. The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient.
To move these molecules against their concentration gradient, a carrier protein is needed.
Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell.
Transport vesicles can move molecules between locations inside the cell, Example: proteins from the rough endoplasmic reticulum to the Golgi apparatus.
Phagocytosis is the process by which a cell uses its plasma membrane to engulf a large particle, giving rise to an internal compartment called the phagosome.
Facilitated diffusion carrier proteins and cell-membrane pumps both are specific for the kids of substances they transport
Na goes out, K comes in
Energy needed to power the sodium-potassium pump is provided by binding of ATP to the pump
Pinocytosis is cell drinking
Exocytosis is a way t release molecules, such as proteins
Active Transport: needs ATP
Sodium Potassium Pump
Sodium-potassium pump exchanges sodium ions for potassium ions across the plasma membrane of animal cells.
Cells are Electrified
Ion- an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Cation- a positively charged ion
Salt in Water
Salt Separates from Chlorine and goes through the Sodium Potassium Pump
Dendrites bring information in
Axons take information out
