Question
Q1. Which of the following is false concerning anaerobic repiration of a glucose molecule?
A. ATPs (4) are made by substrate level phosphorylation.
B. The terminal electron acceptor is closer to the top of the electron transport stairwell than is O2
C. ATPs are made by oxidative phosphorylation but the yield is less than with O2 as the terminal electron acceptor, because of fewer proton pumping steps.
D. The ATP yield by OP is about 20 with nitrate as the terminal electron acceptor.
E. None of the above is false.
Q2. The primary mechanism of drug resistance due to drug-resistance plamids is
A. Enzymatic alteration (inactivation) of the drugs.
B. Increased elimination of the drug through efflux pumps.
C. Altered structural target.
D. Decreased uptake; change in permeability.
E. Increased production of a competitive substrate.

Obligate aerobe B. Microaerophile C Facultative anaerobe D. Obligate anaerobes E. None of the aboveExplanation / Answer
Q1. A. ATP s (4) are made by substrate level phosphorylation. It is false only 2 molecules of ATP is produced per glucose molecule in anerobic respiration.
Q2.A. Enzymatic alteration or inactivation of drugs is the most common and primary mechanism of drugs resistant plasmid.
68. Tamiflu is not a vaccine it is a medicine.
70.E.coli , salmonella and Shigella all are facultative anerobic.
61.c is the false one. Uncoating is necessary for phase.
Rest of all are correct.
