Biology Chapter 5

Chapter 5 info to study for test transport

QuestionAnswer
__________ ____________ 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
