Membrane selectively permeable Active vs passive |
Active-employs carrier proteins and uses ATP Passive- employs carries but it does not use energy. |
|
|
Osmosis |
is the spontaneous net movement of solvent molecules through a semi permeable membrane into a region of higher solute concentration |
|
|
Diffusion |
is the net movement of molecules or atoms from a region of high concentration to a region of low concentration. |
|
|
Endocytosis |
a form of active transport in which a cell transports molecules by engulfing them in an energy-using process. |
|
|
Exocytosis |
is a form of active transport in which a cell transports molecules by expelling them in an energy-using process. |
|
|
Nucleus |
Largest organelle |
|
|
Nuclear envelope |
Sorrounds nucleus |
|
|
Nuclear pores |
large protein complexes that cross the nuclear envelope |
|
|
Chromatin |
Thread like bodies of DNA. |
|
|
Nucleolus |
is the largest structure in the nucleus. |
|
|
Endoplasmic reticulum Rough and smooth |
Rough ER-is involved in some protein production, protein folding, quality control and despatch. It is called ‘rough’ because it is studded with ribosomes Smooth ER-is associated with the production and metabolism of fats and steroid hormones. It is ‘smooth’ because it is not studded with ribosomes |
|
|
Ribosomes |
Small granules of protein and RNA. |
|
|
Golgi complex |
Packages and secretes Protein and Glycoprotein. |
|
|
Mitochondria |
Organelle specialize for ATP synthesis. |
|
|
Phospholipids bilayer and membrane receptors contain what? |
Channel proteins Receptors Carriers Cell-identity markers |
