1. Which of the following statements about Na+ -K+ pump isincorrect?

Select one:

A. The Na+ -K+ pump is an antiport that moves the ions againsttheir concertation gradient.

B. The Na+ -K+ pump is an example of secondary activetransport.  

C. The Na+ -K+ pumps potassium against its concentrationgradient.

D. The Na+ -K+ pump moves Na+ out of the cell and K+ inside thecell.

E. The Na+ -K+ pumps sodium against its concentrationgradient.

1. In general, transport of glucose in and out of cells alwaysoccurs down its concentration gradient.

Select one:

A. True  

B. False  

1. Glucose transport in in the interstitial epithelium (from thelumen or cavity to enterocyte) via the SGLTI.

Select one:

A. Is an example of simple diffusion because glucose moves fromhigh concentration in the lumens to low concentration in theenterocyte.

B. Is an example of secondary active transport because glucoseuses the sodium of gradient.

C. Is an example of facilitated passive transport becauseglucose moves from high concentration in the lumen to lowconcentration in the enterocyte.

D. Is an example of primary active transport that uses a glucoseand ATP hydrolysis.

1. Neurotransmitter are synthesized in the cytoplasm of the cellvesicles for storage. Neurotransmitter use a antipode exchangerprotein that is proton dependent.

Based on the information above, it can be concluded that  

————.

Hint: this transport is an example of secondary activetransport.

A. The PH in the interior of the vesicle is higher than thecytoplasm.

B. The PH in the interior of the vesicle is lower than thecytoplasm.
