Alcohol is a fermentation product of (a) yeast (b) all fungi (c) bacteria (d) both bacteria& yeast 34. In the control of enzymes, when a non-substrate substitute chemical binds to an enzyme, this is called: (a) phosphorylation (b) enzyme repression (c) reduction (d) competitive inhibition (e) feedback inhibition 35. Which of the following is essentially recycled during acrobic respiration: (a) oxygen (b) glucose (c) acetyl CoA (d) pyruvate (e) vitamin A 36. Acetic acid (vinegar) is produced by spoiling the products of (a) acid fermentation (b) anaerobic respiration (c) acrobic respiration (d) alcohol fermentation 37. Anabolism is the same as: (a) synthesis (b) hydrolysis (c) the addition of water (d) fermentation (e)glycolysis 38. Which enzyme is not stored in constant amounts and must be synthesized when needed (a) oxidative (b) exoenzymes (c) constitutive (d) endoenzymes (e) induced 39. The following are all moderate to high energy storage molecules, except (a) ATP (b) ADP (c) NADH (d) FADH (e) FADH, Match the term to its meaning: 40 halophile 41. capnophile 42. alkalinophile 43. psychrophile 44. barophile a. pressure lover b. cold lover c. salt lover d. base lover e. CO, lover 45. Which organism does not traditionally manufacture peroxidase: (a) obligate anacrobes (b) facultative anacrobes (c) aerotolerants (d) strict aerobes (e) microaerophiles

Explanation / Answer

29Staphylococcus: halophile

30 Nocardia: acid fast

31Helicobacter: acidophile

32Clostridium: anaerobe

33 d Both bacteria and yeast.

It is produced by yeast on fermentation and some species of bacteria

34)d competitive inhibition. Binding of a non substrate leads to inhibition of binding of the true substrate and hence it is called competitive inhibition

35 c Acetyl CoA. Acetyl CoA is the end product of the Link Reaction between glycolysis and krebs cycle It is used in the krebs cycle but is recycled back to the link reaction to make another Acetyl CoA molecule
