19- A patient got infection with an unknown bacteria. The microbiologist from the pathological lab isolated the causative bacteria which can be called as a. Psychrofiles b. Barophiles c. Thermophiles d. Mesophiles 20- What is holoenzyme? a. An apoenzymes b. A protein portion of an apoenzyme c. An apoenzyme and its cofactor together d. An enzyme which works best at 37c 21-A NAD+ molecule a. has gained electrons b. has lost electrons c. is an electron donor 22- Simple staining of bacteria tell us about the bacterial.. a. shape b. arrangemerit c. cell wall composition d. a & b e. all of the above

Answer 1

Solutions:-

19) D. Mesophiles( adaptable at room temprature)

20) c. An apoenzyme and its cofactor together (Cofactors, mostly metal ions or coenzyme, are inorganic and organic chemicals that function in reactions of enzymes. Coenzymes are organic molecules that are nonproteins and mostly derivatives of vitamins soluble in water by phosphorylation; they bind apoenzyme protein molecule to produce activeholoenzyme.)

21) c. NAD+ is an Electron donor( because it acceps hydrogen in oxidation and reduction )

22) Simple staining of bacteria tells us about both shape and arrangement so ans. is D. (a & b)
