A protein which embeds part way into a membrane, but does not go all the way through would be classed as an) membrane protein. 11. Prostaglandin synthase converts which molecule into prostaglandin H,? 12. Movement of a lipid molecule from one side of a membrane to another is called diffusion. 13. All pump proteins require which molecule as fuel? 14. The MDR protein belongs to a class of pump proteins called 15. The portion of an ion channel protein which fits a specific ion is called a 16.
