(Reminder: “G proteins” are made up of G-alpha, G-beta, and G-gamma subunits.) How do G-alpha subunits become active when G-protein coupled receptors (GPCRs) bind ligand?

What statement is FALSE about Tim23 protein complex?

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

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
