Question 11 (1 point) of the following, which type of molecule moves directly across a membrane most easily? Large polar molecules, such as glucose Small, uncharged non-polar molecules such as 02. lons, such as chloride (CI) Proteins and other macromolecules
12. Rank the following molecules in their ability to freely diffuse across the membrane (from 1- likely to 4- very unlikely) Large uncharged polar molecules, hydrophobic molecules, small uncharged polar molecules, ion.
which is more likely to cross the plasma membrane, a small uncharged molecule or a large polar molecule?
3 2 Rate of molecule transport 1 Molecule concentration difference across plasma membrane humans, fructose, a disaccharide, is taken up from the intestine by facilitated transport. Respond to the following questions Adressing the transport of fructose molecules as shown in the diagram, above. the number of transport proteins is the same for the membranes with Rates 1, 2, and 3, which arrow corresponds to eatest concentration difference of fructose across the cell membrane? (Click to select) the fructose concentration difference...
A molecule is found to be able to diffuse across a membrane. Which of the following characteristics would best describe this molecule? Question options: hydrophobic negatively charged polar neutral hydrophilic
Question 7 (1 point) Integral membrane proteins stay in membranes because of their small size, which does not allow them to pass through the membrane osmotic pressure from proteins outside the cell. the locations of their polar and non-polar amino acids. diffusion of proteins from the cytoplasm to the membrane.
Exocytosis is a type of cellular transport that allows materials to move across the plasma membrane of a cell. Which of the statements describe properties of exocytosis? Exocytosis uses membrane channel proteins to import materials into the cell. Exocytosis is the primary method of transporting large molecules out of the cell. Exocytosis is the primary method of transporting large molecules into the cell. Exocytosis engulfs materials into the cell through the pinching off of a vesicle from the plasma membrane....
