Characteristic of compartmentalization

Which of the following is NOT a characteristic of compartmentalization? (1 pt.) a. Communication b. Fluid-filled c. Isolation d. Regulation (specialization) e. Structure 2. Draw a cell membrane and label the relative concentrations. and protein on either side of the membrane. (2 pts.)

The cell membrane is made up of many different kinds of proteins. These proteins can be classified as either peripheral, transmembrane, or lipid-anchored proteins. Regardless of their classification, these proteins all play an important role in the function and integrity of a cell. Which of the following properly describes the function of membrane proteins?

( 2 pts.) to provide structural stability for the cell to allow for cell-cell communication to combine with a carbohydrate, providing an immune response and/or cell recognition to combine with lipids to form strong shells that prevent the movement of substances across the membrane to provide a selective barrier to provide fluidity to the membrane to serve as a channel for the transport of molecules between intracellular and intracellular fluid

4. The creation of glycogen from many glucose is an example of (1 pt.) an exergonic reaction. an endergonic reaction. a catabolic reaction. an anabolic reaction. 5. Draw a graph of the free energy of a molecule as a function of time for an endergonic reaction. label on the graph “activation energy” and “net free energy change” (3 pts.)
