Bio Chapter 2


phospholipids make up the membrane and are 2 lipids and a phospate
permeable control/permission for crossing or not of the membrane
diffussion transfer of a substance from an abundant to a lessor abundancy. Requires no cell energy
active transport transfer of a substance from a lessor abundancy to an abundant. This requires cell energy.
endocytosis/phagocytosis process of bringing in a substance from outside of the cell
exocytosis/secretion process of transferring a substance out of the cell
osmosis when water moves from where it is abundant to less abundant
aquaporin protein that allows water to cross through the membrane even though it is not a lipid or lipid solute. It is a channel holding a sole purpose to allow water in
hypertonic solution more solute, less water
hypotonic solution less solute, more water
isotonic solution equal distribution of solutes and water
Microfilaments/Microtubules Non Membranous. Proteins in the shape of tube or thread inside of the cell that gives or maintains the cell structure so It does not collapse
Mitochandria double membrane. Produces energy for the cell. Kidney bean shape. Inner membrane fits only if it is folded because it is large
lysosome is a vesicle filled with digestive enzymes. Membrane bound package from the Golgi. DETOX THE PACKAGE FROM THE GOLGI
Golgi aparatus membrane bound. packages and refines substances from the ER. Packaged for secretion
transport vesicle membrane bound. Membrane pinched off of the ER to transport the protein inside of the membrane to its next stop
Nucleus holds all of the DNA/Chromatin/Chromosomes . this provides the information for what the cell needs to make and how much of it
ribosomes site of protein synthesis. assemble proteins/amino acids for the need of the cell. NON membranous
Endoplasmic Reticulum membrane bound series of channels served as a pathway for the substances to transfer through the cell from one side to another
Smooth ER No ribosomes are attached. Lipids and Fat molecules are assembled
Rough ER Protein production and placement pathway. Ribosomes surrounding the outer rim of the endoplasmic reticulum
cytoplasm the region between plasma membrane and the nuclear membrane that has organelles and cytosol
organelles tiny structures inside the cell
cell membrane outer layer holding the cell together made of phospholipids and proteins
prokaryotic no nucleus, plant cell
eukaryotic nucleus, animal cell usually multi-cellular organisms
organic molecules carbon containing molecules
glucose simple sugar, monosaccharide c6h1206
monomer single building block unit
polymer big molecule monomers joined together
protein long chains of amino acids
polypeptide smaller chains of molecules
biologic molecules carbs, lipids, proteins, nucleic acids
hydrophilic water loving-soluble in water
hydrophobic water fearing-insoluble in water
What can dissolve in water? Other polar hydrophilic molecules
soluble hydrophilic-substance can dissolve
insoluble hydrophobic-substance does not have ability to dissolve
cohesion attraction between 2 like things
adhesion attraction between 2 non like things
capillary action molecules stick to one another and pull each other along, example water molecules pulling each other along up a tree root
polar unequal distribution of charge
water forms solid liquid gas
ICF internal cellular fluid solution= solvent and solutes
ECF extra cellular fluid, external fluid surrounding the cell. solution=solvent and solutes
bacteria single celled organisms. can live on their own.
cell by definition the smallest living unit
organism a group of organ systems organized for an independent existence
nucleic acids macromolecule that carries genetic info of a cell and instructions for the cell function
nucleotides monomer of nucleic acids
simple sugars monosaccharrides
disaccharides 2 monosaccharides undergo a dehydration reaction and form a covelant bond
polysaccharide long chain of monosaccharides linked by a covelant bond
macromolecules large molecule often made by polymerization of smaller molecules
molecules chemical structure having at least 2 atoms held together by a chemical bond
organelles membrane bound compartments or sac within the membrane
atom smallest component of an element
covalent bonds strong bond between 2 or more elements. forms when electrons are shared
organic compounds carbon containing molecules
ionic bonds chemical bond formed between ions of opposite charges
hydrogen bonds weak bonds between partially positive and partially negative elements or molecules
cytosol semi liquid, semi solid gel like consistency, movement allowing in which the organelles of the cell are suspended in
