When bacteria are consumed by macrophages, the macrophages give off chemokines that recruit other immune cells. The chemokines serve as ligands for G-protein coupled receptors. Which of the following is NOT true of G-PCRs?       a.   G-PCRs require GTP to activate a G-protein       b.    G-PCRs bind the ligand extra-cellularly and undergo an allosteric change       c.    The receptor is a G-protein       d.    The G-protein separates into multiple parts that can activate different pathways.

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
