A specific kind of cancer cell requires a large amount of energy. The cancer cells therefore requires:
D) Many mitochondria
Mitochondria are responsible to produce the energy currency of the cell that is ATP through the respiration, and it regulates the cellular metabolism by this way.

3. Cancer cells undergo rapid unrestrained proliferation. The increased reliance of cancer cells upon glycolysis therefore seems paradoxical, since glycolysis generates only 2 ATP from each glucose molecule, whereas complete oxidative respiration of glucose generates up to 36 ATPs per molecule. Which of the following best explains why glycolysis may be advantageous to rapidly proliferating cancer cells? a. Glycolysis generates NADH that can be used as a source of reducing power for macromolecular synthesis. b. Glycolysis produces intermediates that can...

You want to create an anti-cancer drug that destabilizes microtubules, hoping to prevent cell division in the cancer cell line that you are studying. Which of the following drugs would enhance microtubule shrinkage and, therefore, utilize this mechanism of action? Answers A-D A a drug that inhibits GTP hydrolysis by the B-subunit in the GTP cap O B a drug that increases the ability of a tubulin dimer to bind to y-tubulin of the centrosome с a drug that increases...

What is the critical difference between passive and active transport? A. passive requires energy but active does not B. passive requires no energy, but active does C. passive and active each require energy, but passive requires less What is an enzyme? A. a protein that facilitates a reaction B. a protein that supplies water for hydrolysis reactions C. a protein that absorbs water during dehydration reactions The First Law of Thermodynamics states: A. energy can be changed from one form...

5. Which of the following statements about cancer cells is TRUE? a. The respiratory chain is highly active to support fast growth and cell division. b. Cancer cells produce 2 lactate, 1NADH and 4 ATP from glucose. c. Many cancer cells produce less energy than ‘healthy’ body cells because their mitochondria have been lost during cell division. d. Cancer cells produce less energy than healthy body cells due to a malfunction of their TCA cycle. e. Cancer cells are unable...
