     If a membrane protein in an animal cell is involved inthe cotransport of glucose and sodium ions into the cell, which of the following is most likely true? 

    A) The sodium ions are moving down their electrochemical gradient while glucose is moving up. 

    B) Glucose is entering the cell along its concentration gradient. 

    C) Sodium ions can move down their electrochemical gradient through the cotransporter whether or not glucose is present outside the cell. 

    D) Potassium ions move across the same gradient as sodium ions. 

    E) A substance that blocked sodium ions from binding to the cotransport protein would also block the transport of glucose.

    The sodium-potassium pump in animal cells requires cytoplasmic ATP to pump ions across the plasma membrane. When the proteins of the pump are first synthesized in the rough ER, what side of the ER membrane will the ATP binding site be on? 

    A) It will be on the cytoplasmic side of the ER. 

    B) It will be on the side facing the interior of the ER. 

    C) It could be facing in either direction because the orientation of proteins is scrambled in the 

    Golgi apparatus. 

    D) It doesn't matter, because the pump is not active in the ER. 



    A) It will be on the cytoplasmic side of the ER.
