Glucose transporters are either open to the extracellular side or open to the intracellular side of the membrane but never both at the same time. True or False? Movement of an ion against or up its concentration gradient is exergonic. True or False? If an amino acid is transported into intestinal epithelial cells through a transporter that is able to concentrate the amino acid using a sodium ion moving down its gradient, this transporter is an example of primary active transport. True or False? The maximum gradient a primary active transporter can build has a potential energy which in magnitude is greater than or equal to the magnitude of the energy released by ATP hydrolysis. True or False?
