Question

6) True or False? In addition to chloride ions, the CFTR protein also directly transports sodium ions across6 the plasma membrane? A) True B) False 7) In addition to ATP, what are the end products of glycolysis? A) H:O, FADIH:, and citrate B) CO; and pyruvate C) CO, and NADH D) CO; NADH, and pyruvate E) NADH and pyruvate 8) 8) Since mammalian red blood cells lack mitochondria, which of the following processes are used? I. Glycolysis Il. Citric acid cycle III. Oxidative phosphorylation D) I and IIl only A) I only C) II and III only 9 her or Pale: Chloroplyll refects ight in the green range of the visible light spectrum and absorbs all9) other wavelengths. A) True B) False 0) 10) Which of the following statements describes the results of acrobic respiration? A) 02 is reduced and CO) is oxidized. B) CJ 1120, is reduced and CO, ?s oxidized. C) CO2 is reduced and O; is oxidized D) CHiOs is oxidized and O; is reduced. E) O, is oxidized and H:O is reduced. 11) As electrons are passed along the electron transport system from photosystem Il to Cytbóif, they lose 11) energy. What happens to this energy? A) It is used to establish and maintain a proton gradient. B) It excites electrons in the reaction center of photosystem I C) It is released as heat and fluorescence due to the return of these electrons to their ground state. D) It is used to phosphorylate NAD+ to NADPH E) More than one of the above. 12) The concentration of solutes in a red blood cell is about 2%. Red blood cells contain almost no s sucrose or 12) urea. Sucrose cannot pass through the membrane, but water and urea can. Osmosis would cause cells to lyse the fastest when immersed in which of the following solutions? A) a hypotonic urea solution B) a hypertonic sucrose solution C) a hypotonic sucrose solution D) a hypertonic urea solution E) pure water

Explanation / Answer

6- False.

It directly transports Cl ion across the membrane and indirectly help to transport sodium ions.

7) The correct answer is option E that is NADH and pyruvate

CO2 is not produced as there is no decarboxylation reaction in Glycolysis.

8) The correct answer is option A that is Glycolysis only as rbc produce energy by fermentation via anaerobic Glycolysis.

9) True.

Chlorophyll reflects the green light that is why lead appear green as it is in visible spectrum.
