4. This is the only polar portion of a cholesterol molecule and it forms hydrogen bonds with the polar heads of phospholipids. d. –OH group
5. This type of membrane protein will extend throughout the entire membrane touching both the Intracellular fluid and the Extracellular fluid. e. Integral proteins f. Transmembrane proteins g. Integral proteins and Transmembrane proteins
Ans: D
6. This portion of the cell membrane enables cell membranes to produce chemical products. . h. Enzymes
7. Which of the following is a function of a membrane protein that binds with hormones and neurotransmitters? i. Receptors
8. This type of membrane protein helps to anchor proteins in the plasma membrane of neighboring cells to one another. j. Linkers
9. The characteristic of plasma membranes allowing only some substances to move through is known as… k. Selective permeability
10. Which of the following does NOT influence the rate of diffusion? l. Amount of ATP available
12. This is a measure of a solutions ability to change the volume of cells by altering their water content.
d. …show more content…
Facilitated diffusion
13. In this transport process, the energy from hydrolysis of ATP is used to drive substances across the membrane against their own concentration gradients. o. Primary active transport
14. If the solute concentration is greater in the solution on the inside of the cell, compared to the solute concentration of the solution that is outside the cell, then what direction will water move? p. into the cell
15. In this transport process, the energy stored in Na+ or H+ concentration gradient is used to drive other substances across the membrane against their own concentration gradients. q. Secondary active transport
16. This is a transport process by which cells secrete materials, within vesicles, into the extracellular fluid. r. Exocytosis
17. This is a transport process by which cells take up extracellular substances within vesicles.. s. Endocytosis
18. This is an extension of the plasma membrane that will surround a particle outside the cell forming a vesicle. t. Pseudopod
19. The function of the cytosol is. u. Location of chemical
