According to the assigned reading, the ability to feel “lumps” during a breast exam is associated with

The unfolded protein response (UPR): Is triggered when there are too many misfolded proteins in the ER. Is inhibited by BiP molecules. Occurs in the cytoplasm Involves the synthesis of more chaperones in the ER. Inhibits enzymes involved in protein synthesis.

A cell that is actively transporting proteins is exposed to COPII-coat protein antibodies. What happens?   1. Budding of vesicles from the ER to Golgi is blocked  2. Budding of vesicles from Golgi to ER is blocked  3. Budding of vesicles from Golgi to lysosomes is blocked  4. The process of quality control would be affected  5. The process of secretion of components of the ECM would be affected

How do tetanus and botulism toxins cause muscle paralysis?

A VSVG-GFP gene has been mutated to become a temperature sensitive mutant. It is also associated with two types of Temperatures; namely, 32 °C and 40 °C. Which one of the following better describes what happens when the cells are incubated at 40 °C? Hint: assume you are conducting biosynthetic pathway experiments.

The SI unit of Force is:

Which situation below would result in a slower rate of diffusion? 

The cytoplasm is made of: 

Calcium storage in a function of which organelle in muscle cells?
