(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?

Where are receptors for signaling ligands located?

What form of signaling happens during extrinsic apoptosis?

Cofilin binds preferentially to G-actin-ADP, rather than G-actin-ATP in a microfilament. This has the following effect:

What statement is FALSE about Tim23 protein complex?

What is required for the assembly of an adherens junction?

What process in aerobic respiration yields the most ATP?

How do mitogens affect the cell cycle?

In one of the PlayPosits, you learned that sperm cells have mitochondrial derivatives that span the entire length of the tail. In some fruit fly species, the tail can reach up to 2 inches in length. Where does a 2 inch long mitochondrion come from?

Filamin protein is:
