Question
The movement of glucose through proteins called GLUTs (“glutes”) is a textbook example of this type of passive transport. For 10 points each:
[10m] Name this process by which polar molecules diffuse into the cell through a helper protein that is docked in the membrane.
ANSWER: facilitated diffusion [or facilitated transport; prompt on passive mediated transport]
[10e] By contrast, active transport of glucose occurs in this organ’s renal tubules, where it is coupled to the removal of sodium from the filtrate of the glomerulus.
ANSWER: kidneys
[10h] The aptly named “Sugars Will Eventually be Exported Transporters,” or SWEETs, exchange sugars without ATP and are in a superfamily named for these light-sensitive GPCRs. Retinal is usually found attached to these proteins.
ANSWER: opsins [accept rhodopsins or channelrhodopsins]
