  10. An ATP synthase, which makes ATP when H+ crosses a membrane through its interior. A calcium pump moves calcium ions across the membrane; requires ATP energy. A glucose transporter allows glucose to cross the membrane through a channel in its interior. EXTRACELLULAR FLUID LIPID BILAYER B cell receptor. It binds to bacteria, other foreign agents. Recognition protein that identifies a cell as belonging to one’s own body. CYTOPLASM phospholipid protein filaments of the cytoskeleton Fig. 4-9, p. 57
