Which of the following is incorrect about membrane transport systems? a.   Glucose transport in red blood cells is a uniport system   b.   The Na+/K+ ATPase is an antiport system   c.   The H+/K+ ATPase is an active transport system   d.   The chloride-bicarbonate exchanger in erythrocytes is a uniport system

if a cell has a net positive charge inside and there is a net negative charge outside the cell, which of the following is correct (if the membrane is permeable to each substance and the concentration of each is the same inside and outside the cell)? a. negative ions will move into the cell b. positive ions will move into the cell c. neutral ions will move into the cell d. negative ions will move our of the cell

Model 1 and Model two are diagrams showing the process of two types of bulk transport which require energy. Which of the following statements correctly describes the type of transport that is occurring in Model 1 and Model 2? A . Model 1 and 2 are types of passive transport. B . Model 1 and 2 help to transport only one molecule at time. C . Model 1 shows endocytosis, where the cell surrounds molecules from outside the cell and takes the molecules into the cell. D . Model 2 shows endocytosis, where the cell surrounds molecules from inside the cell and releases them outside of the cell.
