What conformation does Myosin II have to be in for the trailing edge of a migrating cell to retract? 

What statement is FALSE about Tim23 protein complex?

In what order does a Listeria infection occur? 1. Listeria bacterium produces ActA and harnesses host cell’s resources to create a microfilament “rocket” 2. Listeria bacterium binds to a receptor on the host cell surface 3. Listeria bacterium is ingested by the host organism 4. Listeria bacterium releases a protein that breaks apart the phagosome, allowing the bacterium to evade destruction 5. Listeria bacterium is not detected by the host cell as as a pathogen because it is surrounded by a membrane entirely made of up the host’s proteins and phospholipids 6. Listeria bacterium reproduces via binary fission

How do mitogens affect the cell cycle?

What happens when a GTP cap is lost at the plus end of a microtubule?

TRUE or FALSE: Cardiolipins are located in both the mitochondrial inner membrane AND the plasma membrane of eukaryotes. 

Why do some mitochondria have more cristae than others? Would you expect any difference in ATP output between mitochondria carrying different amounts of cristae?

A mitochondrion is carried by a kinesin motor protein 100’s of nanometers to the opposite end of a cell. This is an example of:

What type of signaling molecule binds to a receptor that then travels into nucleus to act as a transcription factor?
