Biology Chapter 5
Chapter 5 info to study for test transport
| Question | Answer |
|---|---|
| __________ ____________ is the plasma membrane regulating traffic in and out of cell. | Cell transport |
| The _________ decides when stuff enters or leaves. | Cell |
| _________ ______________ is substances move from higher to lower concentration, no additional energy is required to balance. | Passive transport |
| In passive transport, there is a low amount of H2O outside of the cell. In the plasma membrane, there is a high amount of H2O and it needs more. A signal is sent requesting more. True or False? | False |
| _________ ___________ is substances move from lower to higher concentration, additional energy is required to balance. | Active transport |
| Active transport requires both a___________ __________ and lots of ATP. | Transport protein |
| In active transport, inside of the cell, there is too much Na+, so the excess is moved outside of the _________ _________ thru energy. | Plasma membrane |
| __________ _____________is movement independent of gradients, additional energy is required to balance. | Bulk transport |
| In bulk transport, regardless of concentration, toxin + energy, the _____________ ________ ______________ ____________. | Toxin is kicked out |
| Bulk transport takes large molecules into a cell by _________ them. | Engulfing |
| ____________ enter a metabolic pathway and then are modified to produce _____________. | Reactants/products |
| Bulk transport can ________ protein into cytoplasm or embed into cell wall. | Eject |
| During bulk transport, it forms a vesicle __________cell. | Inside |
| In bulk transport, _________ __________ takes them into the cell. | Vesicle formation |
| Transport macromolecules out of cell via vesicle formation and often result in secretion is called ______________. | Exocytosis |
| ____________ are often too large to be moved by transport proteins during bulk transport. | Macromolecules |
| One type of pump that is active in all animal cells, but is especially associated with nerve and muscle cells, moves sodium ions (Na+) to the outside of the cell and potassium ions (K+) to the inside of the cell. These two events are linked, and the carrier protein is called a _________-_________ __________. | Sodium-potassium pump |
| Proteins involved in active transport are often called _______, just as a water pump uses energy to move a substance against its concentration gradient. | Pumps |
| Receptor-mediated endocytosis are receptors for particular substances found in _______ pit-selective and more efficient. | Coated |
| Be able to recognize the different ways that _____________ get through the plasma membrane of a cell is through passive transport, active transport and bulk transport. | Materials |
| Phagocytosis (___________) cell surrounds, engulfs, and digests particle (lysosomes). | Ingests |
| _________ means movement into cell. | Endocytosis |
| Pinocytosis (____________ __________) vesicle forms around liquid or small particles (ions, aa). | Drinks in |
| _________________ is the ingestion (drinks in) of liquid into a cell by the budding of small vesicles from the cell membrane. | Pinocytosis |
| Phagocytosis (_____________) cell surrounds, engulfs, and digests particle (lysosomes). | Ingests |
| Phagocytosis is cell eating while pinocytosis is cell drinking. True or false | True |
| _________ means movement into cell. | Endocytosis |
| Phagocytosis has smaller vesicles over pinocytosis. True or False | False |
| Phagocytosis engulfs much smaller particles than pinocytosis. True or false | False |
