question | answer |
6 functions of the cell | Basic unit of life, protection and support, movement, communication, cell metabolism, and energy release, inheritance |
cell membrane | outermost component of the cell, is a wall |
extracellular substance | substance outside the cell |
intercellular substance | substance in the cell |
mosaic model | arrangement of molecules in the cell, cell membrane moves like bobbers on water |
nucleus | brain of cell, DNA |
nucleolus | site of ribosomal RNA and ribosomal protein synthesis |
rough ER | site of Protein synthesis |
Smooth ER | Site of lipid synthesis |
Golgi Apparatus | modifies protien structure and packages protiens in secretory vesicles |
lysosomes | contains enzymes that digest material taken into the cell |
mitochondrion | site of aerobic resporation and the major site of ATP synthesis |
Microtubuals | holds up the cell |
cilia | moves substances over surface of cell |
flagella | on sperm cell surface with one per cell |
microvilli | extensions of cell surface with many on cell, increase surface area of certain cells |
ribosomes | cytoplasmic organelle were protein synthesis occurs |
cytoskeleton | consists of proteins that support the cell, enable the cell to change shape |
four ways molecules pass through cell membrane | through phospholipid membrane, membrane channels, carrier molecules, and vesicles |
solution | consists of one or more substances |
solutes | dissolves into original, added to first substance |
solvent | substance that the solute is dissolved into, first substance that 2nd is added to, usually larger |
diffusion | substance spreads throughout evenly |
concentration gradient | the measure of the difference in the concentration of a solute in a solvent between two points |
osmosis | through membrane, ex. air through screen |
osmotic pressure | the force required to prevent the movement of water across a selective premeable membrane |
hypotonic | solution usually has a higher of solutes and a lower concentration of water than cytoplasm in the cell |
Facilitated Diffusion | a mediated transport process that moves substances into or out of cells from a higher or a lower concentration |
Active Transport | a carrier-meiated process that moves substances from regions of a lower concentration to ones of higher concentration against the gradient |
Sodium Potassium Pump | moves sodium ions out of cells and potassium ions into the cell |
endocytosis | the cell bring in food and water |
exocytosis | the cell getting rid of wastes and other bad things |
glycolysis | the breakdown of sugars by a series of chemical reactions within the cytoplasm of a cell |
aerobic respiration | breakdown of glucose in the presence of oxygen to produce carbon dioxide, water, and approximately 38 ATP molecules |
anaerobic respiration | breakdown of glucose in the absence of oxygen to produce lactic acid and two ATP molecules |
organelles | "little ograns" in the cell |
