What transport process couples the movement of solute A against its electrochemical gradient with the movement of solute B with its electrochemical gradient that was previously established using cellular energy (ATP)?

True or false: Carbohydrates are nonpolar.

If there is 0.2 M glucose along with 0.15 M NaCl in solution, what is the osmolarity of this solution?

True or false: Using the Na+/K+ pump (ATPase), 2 potassium ions are moved out of the cell per ATP.

What is the final electron acceptor in the reactions of the electron transport chain?

True or false: Carbohydrates include glucose, lactose, and glycogen.

If the chemical driving force for a potassium ion is in opposition to the electrical driving force for the potassium ion, which of the following will be true?

Like sodium chloride, each sodium fluoride unit (NaF) dissociates to two ions when dissolved in water. What is the osmolarity of an aqueous (i.e., in water) solution containing only 25 grams of NaF per liter of water?

Based on your knowledge of signal amplification, which type of chemical messenger can have relatively small concentrations within the bloodstream and still get a large response?

While working in a pharmacology lab, you develop a new compound that you think shows a lot of promise; however, you observe a concerning side effect: NADH now interacts with complex II instead of complex I. True or false: This change would lead to increased efficiency of ATP production.
