Question

use the diagram below to give the appropriate response to questions 52-57: но HO Но Іно Analyze the diagrams above and match the appropriate figure by shading your seantron or to match the following terms 52. isotonic 53. flaccid 54. plasmolyzed 34 turgid 56.hypertonic 57.hypotonic 58. Ascorbic acid, which is found in citrus fruits, acts as an inhibitor to catecholase, the enzyme responsible for the browning reaction in fruits such as apples, peaches, and pears. One explanation for the inhibiting function of ascorbic acid could be its similarity, in terms of size and shape, to catechol, the substrate of the browning reaction. If this explanation is correct, then this inhibition is most likely an example of inhibition a competitive b. indirect c. noncompetitive d. allosteric e feedback

Answer 1

52 ans). Isotonic: This term matches with the figure B. (Scantron B should be shaded)

53 ans). Flaccid: This term matches with the figure B. (Scantron B should be shaded)

54 ans). Plasmolysed: This term matches with the figure A. (Scantron A should be shaded)

55 ans). Turgid: This term matches with the figure C. (Scantron C should be shaded)

56 ans). Hypertonic: This term matches with the figure A. (Scantron A should be shaded)

57 ans). Hypotonic: This term matches with the figure C. (Scantron C should be shaded)

Explaination:

52). Isotonic is a term used for solution in which the concentration of both water and solute are equal on both sides of the cell membrane, and osmotic pressure is the same inside and outside the cells.

53). When the overall gain of water molecule is equal to zero for a cell as in figure B cell becomes Flaccid in structure.

54).  When the water molecules moves out of the cell membrane as in figure A cell will shrink and enters plasmolysed state.

55). When a cell placed in hypotonic solution cell swells as the water molecules enters the cell and becomes turgid as in figure C.

56). Hypertonic is a term used for solution in which there is a higher concentration of water molecules inside a cell than outside the cell, cell will also have more osmotic pressure outside the cell than inside the cell.
57). Hypotonic is a term used for solution in which there is a higher concentration of water molecules outside a cell than inside the cell, water enters the cell and fills vacuole thereby leading the contents of cell to apply force on cell wall.
