Explanation / Answer
1.a.Oxidation is the same as Dehydrogenation andreduction is the same as Hydrogenation.Thus in glycolysis oxidation reduction takes place .
100.a. An antimicrobial is an agent that kills microorganisms or stops their growth.
32.c.Chloramphenicol is a bacteriostatic by inhibiting protein synthesis. It prevents protein chain elongation by inhibiting the peptidyl transferase activity of the bacterial ribosome.
33.d.It inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis; therefore,ampicillin is usually bacteriolytic.
22.c Rifampicin inhibits bacterial DNA-dependent RNA synthesis by inhibiting bacterial DNA-dependent RNA polymerase. The inhibitor prevents RNA synthesis by physically blocking elongation, and thus preventing synthesis of host bacterial proteins.
23.e.Polymyxin B is an antibiotic primarily used for resistant Gram-negative infections. It has a bactericidal action against almost all Gram-negative bacilli except the Proteus and Neisseria genera.Polymyxins bind to the cell membrane and alter its structure, making it more permeable.
24.a.Tetracycline antibiotics are protein synthesis inhibitors, inhibiting the binding of aminoacyl-tRNA to the mRNA-ribosome complex. They do so mainly by binding to the 30S ribosomal subunit in the mRNA translation complex.
16.d.The production of ATP by the electron transport chain is driven by: hydrogen gradient.
13.c.Catabolism is the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism.
14.tAnabolism is the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism.
10. d.ATP synthase: is the enzyme in the cell membrane that makes ATP
