SOLUTION:C
2. An ExperimenT Is Done To Measure The UpTake Of An Amino Acid InTo A Cell. The
Following DaTa Are ObTained:
N
If Na+ Is Removed From The ExTracellular BaThing SoluTion, Or If A Drug Is Added ThaT
PrevenTs The Cell From Making Adenosine TriphosphaTe (ATP), The UpTake Of Amino
Acid InTo The Cell Is Markedly Reduced. According To This InformaTion, Which Of The
Followingmechanisms Is Probably Responsible For The TransporT Of The Amino Acid InTo
The Cell?
