Question

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 to produce as much energy as healthy body cells because glucose oxidation finishes at the end of glycolysis.

8. Which of the following statements regarding anchorage dependence is TRUE?

a. As long as they are adherent, cells will divide even if the environment doesn’t contain the proper growth factors.

b. Anchored cells don’t move up through tissues to replace old cells.

c. In order to function, all animal cells need a surface to adhere to.

d. Cancer cells are often anchorage independent for proliferation

e. In vitro non-cancer cells will stop dividing if they are crowded.

10. Eukaryotic cells possess which of the following traits?

a. Uncompartmentalised cytoplasm

b. Chromosomes that float freely in the cytoplasm

c. Circular chromosomes

d. Both compartmentalization and chromosomes that float freely in the cytoplasm

e. Both compartmentalization and membrane-bound organelles

Answer 1

Q5.answer. c) Many cancer cells produce less energy than healthy body cells because their mitochondria have been lost during cell division.

Cancer cells are those cells that form a pure tumor or we can say form a coalition or junction of abnormal cells, causing blood flows. Cell division is the action that the body uses for development and repair. A parent cell divides two daughters. Similarly, daughter cells are used to make new tissue. Healthy cells stop bleeding when that does not call for the daughters of the baby, and replication of cancer cells continue. The body is disseminate from one part to the other and in a process the metastasis is known in the same way.

Q8.answer) c. In order to function, all animal cells need a surface to adhere to.

Most animal cells will not proliferate if they have no surface to adhere to as most animal cell division depends on the cells possessing a surface to adhere to or to be attatched to and this is known as anchorage dependence.

Q9.ANSWER) e. both compartmentalization and membrane-bound organelles

As eukaryotic cells are compartmentalized, with the compartments largely made up of membrane-bound organelles. On the other side, prokaryotic cells do not possess membrane-bound organelles and are not compartmentalized
