Which example of bulk transport allows the cell to
take in fluids
a. Receptor-mediated endocyptosis
b. pinocytosis
c.phagocytosis
d.hydrocytosis
ANS. Pinocytosis
Pinocytosis (literally "cell drinking") is a form of endocytosis in which a cell takes a in a smaller amount of extra cellular fluid.

Receptor-mediated endocytosis depends on functional cell surface receptor proteins True O False Question 29 1.5 pts A certain cell needs to move a molecule of sucrose out of the cell. The concentration of sucrose in the extracellular space is greater than that in the cell's cytoplasm. What type of transport mechanism would the cell use? O passive transport exocytosis active transport osmosis In the lipid bilayer the phospholipid tails are hydrophobic hydrophilic Question 31 1.5 p A human white blood...
Which of the following processes only moves substances into a cell? exocytosis active transport endocytosis facilitated diffusion What process do white blood cells use to engulf bacteria? pinocytosis phagocytosis receptor-mediated endocytosis exocytosis
You can recognize the process of pinocytosis when O the cell is engulfing extracellular fluid the cell is engulfing a large particle O a receptor protein is involved A white blood cell engulfing a bacterium is an example of receptor-mediated endocytosis pinocytosis exocytosis phagocytosis facilitated diffusion
11. For a hormone to elicit a specific response from a cell, the cell must possess a. a synapse. b. a cell body. c. dendrites specific to the hormone. d. receptor proteins specific to the hormone. 12. In a cell, the difference in ion concentration between the intracellular and extracellular fluids results from a. active ion transport. b. passive diffusion of ions. c. bulk movements of intracellular and extracellular fluids. d. both active ion transport and passive diffusion of ions.

For each of the following foreign bodies identify the type of cell that ingests them and the method by which it ingests the foreign body (pick from neutrophils, macrophages or FBGCs for the cell type and phagocytosis, pinocytosis or receptor mediated endocytosis for the method of ingestion): a) Gold particles 1 nm across b) Necrotic cell tissue c) PGA particles (15-20 microns across) For each of the following foreign bodies identify the type of cell that ingests them and the...
10. In a given molecule which are the determinants for its transport through a membrane (active/passive/receptor mediated etc.)? Explain in detail. (5 points)
QUESTION 44 Describe the path a cell surface receptor will take when being synthesized (starting at the beginning of translation) to its expression on the plasma membrane - be sure to indicate the orientation of the receptor and any other processing that is undergoes. Describe the different possible fates of a receptor once it is internalized by receptor-mediated endocytosis. TTTT Paragraph Arial 3 (12) % Doa Τ' Τ.
Calcium ions move out of the cell against a concentration gradient. What drives this active transport? a) vesicles fusing with the membrane b) receptor-mediated exocytosis c) diffusion d) hydrolysis of ATP
