Which of the following is correct about a symporter? it is a form of passive transport it moves one substance at a time against its concentration gradient it utilizes ATP it moves large substances using endocytosis/exocytosis none of the above are correct

Which of the following has the largest impact on whether diffusion alone will move nutrients within an organism? Group of answer choices Shape of organism Size of organism Environment of organism Nutrient being moved Atmosphere around organism

Which of the passive transport processes requires hydrostatic pressure to transport molecules across membranes in the body? Multiple Choice   Osmosis   Filtration   Facilitated diffusion   Pinocytosis   Diffusion

What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.

Mark the flow of water with an arrow for cells that have been placed in solutions of differing tonicity. Indicate what will happen to a plant and animal cell under each of these conditions. Direction of osmosis Plant cell Animal cell shape shape minor swelling The solute concentration outside the cell is isotonic (or equal) to the inside of the cell. No change swelling and lysis plasmolysis crenation Reset Zoom (a) Outside isotonic The solute concentration outside the cell is hypertonic to the inside of the cell. (b) Outside hypertonic The solute concentration outside the cell is hypotonic to the inside of the cell. (c) Outside hypotonic Oo Solute Cytosol ©2018 McGraw-Hill Education. Check m

Match the transport process to the correct description or example. Exocytosis is: Group of answer choices transport of signal molecules out of an endocrine cell transport of a steroid hormone into a cell breaking of a covalent bond to create new molecules making a new covalent bond transport of glucose into a cell, against its concentration gradient transport of glucose out of cell, with its concentration gradient import of an entire bacterium into a white blood cell transport of sodium out of a neuron transport of large macromolecules into a cell

What would happen if all of the Na+/K+ pumps in a cell stopped working? One of the other transport proteins will immediately take over The voltage across the membrane will immediately get more negative The voltage across the membrane will immediately get more positive Nothing will change Gradients and voltage across the membrane will slowly run down All of the above

The following type(s) of gradient can drive different fluxes across the cell membrane:     Voltage gradient.     Pressure gradient.     Concentration gradient.     Osmotic pressure gradient.     All of the above.

Which transport mechanism would allow a solute to move from its area of low concentration to its area of high concentration, another words against its concentration gradient? secondary active transport osmosis channel mediated facilitated diffusion carrier mediated facilitated diffusion simple diffusion Aa JO stv A К Pro
