Q33) D. Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
Na-glucose co-transport is a type of active transport in which the energy generated from the transport of sodium is used in the transport of glucose.
Q34) d. cotransport.
Cotransport need concentration gradient of H+ ions across the membrane for it to transport phosphate inside the cell.
Q35) C. membrane potential.
membrane potential is a concentration gradient across the membrane.
33) Which of the following is most likely true of a protein that cotransports glucose and...
How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...

Discard the answers I chose Match the following scenarios with the most specific type of transport used. Some choices may be used more than once. A A white blood cell enguits a bacterial cell A A paramecium swims close to some debris, wraps its membrane around the debris, and pulsit inside, creating a food Vacuole D. An amoeba wraps its cell membrane around a region of dissolved nutrients in water and pulls it inward, making a small vacuole A Phagocytosis...
Magnesium ions move out of a cell through a transmembrane protein down (i.e. with) their concentration gradient. The energy harvested from this movement of magnesium ions is used to move sodium ions into the cell against their concentration gradient. This is an example of which type of transport? symport ABC transport antiport facilitated diffusion
