H.O.C.P
homeostasis, organelles, and cell specialization test
| Question | Answer |
|---|---|
| Cell Membrane is also called the.. | Plasma Membrane |
| Passive Transport.. | Doesn't need ATP energy |
| Active Transport.. | Needs energy |
| Membrane Transport is.. | movement across cell |
| Diffusion is.. | movement of molecules from high to low concentration |
| Passive's direction is.. | Up to down |
| Active's direction is.. | Down to up |
| What are the kinds of passive transport | simple and facilitated |
| Simple diffusion | does not need help to move by carrier protein |
| Facilitated diffusion | needs help to move by carrier protein |
| Integral Proteins | act as channels to move substances across membrane |
| osmosis is | diffusion with water |
| the fluid bilayer's structure helps | houses the proteins and limit what goes in and out the cell |
| hydrophobic | non polar, come on in |
| hydrophillic | polar, no getting in |
| diffusion occurs | along a concentration gradient |
| rate of diffusion depends on | temperature, charge, diameter of diffusing molecules, steepness of concentration gradient |
| comfrimational change | shape change |
| feedback is | what happens is what happens next |
| kinds of feedback | pos and neg |
| negative feedback | effectors OPPOSE change |
| positive feedback | effectors ENHANCE change |
| homeostasis | maintains an internal environment |
| what are the three components of homeostasis | receptor, control center, effector |
| receptor | senses a change in environment and signals CC |
| control center | finds how to respond and signals effector |
| effector | receives signal and adjusts |
| neg feedback loop | changed variable goes back |
| pos feedback loop | escalation change |
| lvls of org | atom, molecule, mm, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere |
| Macromolecules | carbs, phosphate, proteins, lipids |
| Pro | No MBO, No nucleus, Free floating gene material |
| Eu | MBO, Nucleus |
| solute | being dissolved |
| solvent | whats dissolving it |
| water is the | universal solvent |
| water to.. solute to.. | water, solute |
| Hypertonic | SHRINKS LIKE DOG - water/solvent, +solute |
| Hypotonic | SWELL LIKE HIPPO +water/solvent, -solute |
| Isotonic | everything stays but it still changes |
| Ion is the | pos/neg charge to an atom |
| ion pumps are | special proteins that move ions to get ionic and voltage gradient |
| cotransort is like | sobenna, H+, being carried by ken's backback, sucrose, to get ijn the movies, kicked out by ATP. |
| ATP is in a cycle of | splitting constantly, ADP + P = ATP |
| ATP comes back together because of | free phosphate |
| ENDOcytosis is | import of material to cell by INfoldings of plasma membrane |
| kinds of ENDOcytosis | phago, pino, receptor |
| CYTOSIS | Active |
| phagocytosis | cell eating |
| pinocytosis | cell drinking |
| Endocytosis receptor | coated pits tbat need right receptor |
| when homeostasis is lost... | disease comes along |
