a) 1

b) 10

c) 100

d) 1,000

35) The acid fast stain reacts with:

A) a cell wall protein

B) a plasma membrane protein

C) a cell wall lipid

D) a plasma membrane lipid

E) a cytoplasmic carbohydrate

36) The basal body is part of the:

A) flagellum

B) cytoplasm

C) chromosome

D) F-pilus

E) Extraorbital bodies

37) Nucleotides within the same strand of DNA are held together by:

A) ester bonds

B) glycosidic bonds

C) peptide bonds

D) all of the above

E) none of the above

39) If a major macromolecule of the cell contains P, it may be:

a) membrane lipid

b) carbohydrate

c) water

d) nucleic acid

e) a and d (I think E is the answer)

TRUE OR FALSE:

17) Glycogen is an example of a carbohydrate.

56) The cells of a true bacterial colony come from many originating bacteria.

57) Superoxide dismutase is an enzyme involved in oxygen detoxification.-

Explanation / Answer

35) a cell wall lipid.

That is why acid fast stain is used to stain the acid fast bacteria like Mycobacterium to see under microscope.

36 - B cytoplasm

Basal body is a cylindrical organelle, within the cytoplasm of flagellated and ciliated cells, that contains microtubules and forms the base of a flagellum or cilium.

37-A Ester bonds.

Glycosidic bonds is formed with the Purine/pyrimidine and sugar. And this does not hold the DNA strand.

Peptide bond is formed in the proteins not in the nucleotides.

38) E protein and nucleic acid.

Carbohydrates contain carbon hydrogen and oxygen

Lipids in the rare form contains nitrogen

C, H, O AND N are the molecules that can be found in proteins and nucleotides.
