- 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 systemarrow_forwardThe principal force driving movement in diffusion is: a) gravity b) random movement of particles in a fluid c) particle size d) electrical forcesarrow_forwardWhether in a gas, a liquid, or a semisolid, diffusion always occurs a). at the same rate. b). from high to low solute concentration. c). faster at lower temperaturesd). from low to high solute concentration.arrow_forward
- If partial pressure of oxygen were about 35 MMHG and the capillaries then a. the cells would not need extra oxygen b. CO2 pressure would be very low in the cells c. it would not be able to diffuse into the tissue cells d. it would easily travel and capillaries and if used to the needy cellsarrow_forwardI believe I use the diffusion law on this: (Diffusion Constant × ∆Concentration × Area) / Thickness. Then change the constant into micrometers (x10^-12). Maybe use the fact that oxygen = 16 grams/mol. Am I on the right track? Thank you for any help you can provide.arrow_forwardWhich of these statements about carrier-mediated facilitated diffusion is true? a. It uses cellular ATP. b. It is used for cellular uptake of blood glucose. c. It is a form of active transport. d. None of these are true.arrow_forward

The amount of O2 that travels dissolved in the plasma and not attached onto hemoglobin is approximately a. 98% b. 7% C. 35% d. 2%arrow_forwardWe get iodine in our diet but over 99% of it ends up in our thyroid gland with very little in the rest of the body. Could this occur by diffusion?arrow_forward
- which of the following processes causes most of the carbon dioxide from the blood to move into the alveoli? a. passive transport using a carrier proteins b. active transport using energy c. conversion to carbon dioxide d. diffusion down a concentration gradientarrow_forwardthe reason solutions for injection normally contain either 150mm NaCL or 5% dextrose is that these a. are necessary for metabolism b. are hypertonic to the blood and cells c. are isotonic to the blood and cells d. are hypotonic to the blood and cellsarrow_forwardIf a membrane protein in an intact erythrocyte reacts with a membrane-impermeable reagent, what can you conclude about the protein?
