Question

Unlike a disinfectant, an antiseptic: sanitizes. rather than sterilizes. destroys all microorganisms. is nontoxic enough to be used on human skin. requires heat to he effective. can be used in food products. For each glucose made in the dark reactions of photosynthesis the number of ATP:NADPH required is 12:12 18:12 12:18 18:18 6:6 To describe a type of photosynthesis as "oxygenic" implies that oxygen is consumed. oxygen functions as a catalyst. is produced. oxygen is the terminal electron acceptor E. oxygen is not required Urine samples (one microliter volume) arc commonly spread onto blood agar and MacConkey agar. A urine sample with more than 100.000 organisms/ml (100 colonies on the plate) is considered indicative of infection. If a urine sample containing 4,000 with a generation time of 30 minutes, sits for 3 hours before finally being assayed, how many bacteria will then be parcel/ml? 10.000 64,000 128,000 320.000 none of the above Glycolysis requires oxygen. produces 3 ATP molecules. Produces 4 molecules of NADH. may occur under aerobic or anaerobic conditions. B and C Fermentation uses an inorganic molecule as the final electron acceptor. starts with private and uses organic molecules as the final electron acceptors. results in the production of a large amount of A IP. produces different fermentation products which arc typical of different types of organisms. B and D
