QUESTION 8 Which of the following are functions of transmembrane proteins? Transport B. Enzymatic activity CCell-cell recognition D. A & B E. A, B, & C QUESTION 9 Ligand-gated ion channels are opened by a molecule B, membrane potential o light D. pressure E temperature QUESTION 10 If a plant cell is placed in hypotonic solution it will most likely be A faccid B. metabolized lysed plasmolyzed E. turgid

Solution

8)E)A,B,C because

transport as they control the traffic by selecting specific different molecules from protons

Enzymatic activity is a process which happens when the protein that is built into the membrane might be an enzyme .This happens with respect to its active site exposed to substances in the adjacent solution.

Moreoer Cell-cell recognition is a process which happens when some glycoproteins are able to serve as an identification tags .These tags are usually recognized by other cells that are present.

9)B)Membrane potential

becausee ion channels help to stablish a resting membrane potentia lthat helps in haping action potentials and also the other electrical signals.It also helps in gating or opening the flow of ions across the cell membrane.

10)E turgid

because whenever we have the plant cell which is placed in a hypotonic solution , then the plant takes up water by the process of osmosis ,It eventually swells up but at the same time the cell wall prevents the cell from bursting. Moreover,The plant cell is said to have become turgid which means swollen and hard.
