A red blood cell that displays a biconcave disc shape must be in which of the following solutions? hypertonic solution distilled water isotonic solution ocean water hypotonic solution
Which feature is typical of primary active transport? The transport protein must cross to the correct side of the membrane before the solute can bind to it. The transport protein is irreversibly phosphorylated as transport takes place. The transport protein catalyzes the conversion of ADP to ATP. The solute moves against the concentration gradient. A concentration gradient provides the energy to move substances against their concentration gradient.
Which of the following would be most likely to move across the membrane without a transport protein? Water, because it is small and polar O2 (molecular oxygen), because it is small and nonpolar A cation, because it is small and positively charged An anion because it is small and negatively charged
Which is the complete description of active transport? The movement of molecules from an area of higher concentration to an area of lower A concentration across a selectively permeable membrane which uses metabolic energy from ATP. The movement of molecules from an area of higher concentration to an area of lower B concentration across a selectively permeable membrane which does not use metabolic energy from ATP. The movement of molecules from an area of lower concentration to an area of higher C concentration across a selectively permeable membrane which uses metabolic energy from ATP and transport proteins. The movement of molecules from an area of lower concentration to an area of higher D concentration across a selectively permeable membrane which does not use metabolic energy from ATP and transport proteins.
