Which is not true concerning the cell wall of bacteria? A. It determines the shape of the bacteria. B. It is the site of group translocation. C. It contains peptidoglycan. D. It may be targeted by antimicrobials. E. It prevents the bacteria from bursting.
The 70S ribosomes of Eukarya form part of the evidence for the endosymbiont theory
Oxidation of proteins is achieved most readily
A urine sample with more than 100,000 organisms is considered indicative of infection. A urine sample containing 5,000 bacteria, with a generation time of 30 minutes, sits for 3 hours before finally being assayed. How many bacteria will then be present within the sample?
B. 64,000 C. 320,000 D. 10,000 E. >1,000,000 BACCA A. lowest resistance B. medium resistance C. highest resistance protozoan cyst, fungi enveloped virus endospore prion vegetative bacteria What happens to the carbon molecules in the pyruvic acid that goes through the TCA cycle? A. They continue on to the fermentation pathway B. They get incorporated into cell material C. They become carbon dioxide D. They form "energy storage molecules" and are stored by the cell E. They are excreted as waste organic acids
If the processes of aerobic and anaerobic respiration are basically similar – differing only in the terminal electron acceptor –why do they produce different amounts of energy?
others. The amount of energy that can eventually be obtained is directly proportional to the degree of difference between the high-energy electron carrier and the eventual terminal electron acceptor. The greater the difference, the greater the energy obtained. Oxygen typically has the highest degree of difference of the terminal electron acceptors utilized. B. There is no functional difference between the two processes - they will both result in the same overall net amount of energy produced. C. Different amounts of energy are produced because anaerobic respiration is a thermodynamically more stable process than aerobic respiration D. They produce different amounts of energy because not all electrons are brought into the electron transport chain with the same amounts of potential energy. NADH, for example, enters the electron transport chain 'further up' than FADH 2 -so it will result in less proton motive force being generated, therefore less eventual ATP. Concerning catabolism and anabolism A. they refer to reactions solely dealing with the metabolism of lipids B. the intermediates of one serve as the reactants in the other C. the energy gathered in one is utilized in the other D. they refer solely to the reactions involved in synthesis of carbohydrates E. the intermediates of one serve as the reactants in the other AND the energy gathered in one is utilized in the other
