Signal transduction pathways benefit cells for all of the following reasons except :   a. they enable different cells to respond appropriately to the same signal.   b. they can amplify and diversify a signal.   c. they help cells use up phosphate generated by ATP breakdown.   d. they help cells respond to signal molecules that are too large or too polar to cross the plasma membrane
Many common medications function by interrupting the normal operation of certain signal transduction pathways. Which of the following describes a possible mechanism by which a certain medication may interrupt a signal transduction pathway? A A medication enters the target cell and triggers apoptosis by causing the release of di- gestive enzymes from cell lysosomes. B A medication interacts with the phospholipid bi-layer of the cell membrane and in- creases its permeability. с D A medication binds to membrane-bound glucose proteins and acts as an allosteric in- hibitor that prevents the intake of glucose by the cell. A medication diffuses through the membrane of a target cell and inhibits an enzyme that normally synthesizes a second messenger.
In farming communities, there is a concern that over irrigation can leech nutrients out of the soil, flood a farm area,  and add salt to the soil in a process called salinization.  The overall negative results are that some plants cannot germinate (grow from seed) and other adult or growing plants will die.  Explain what is happening on the cell level, in regards to transport across the cell membrane, why seeds might not germinate, and why adult plants might die.
