MIP 300 Final Exam Questions and Answers What is the minimum number of glucose molecules a bacterium that performs anaerobic respiration would need to metabolize in order to get 380 ATP - Answer-11 Facultative anaerobes can do either aerobic respiration or fermentation. In an anaerobic environment, which of the following could be an electron acceptor used by such a facultative anaerobe? - Answer-pyruvate When you follow a single Glyceraldehyde 3-P molecule forward toward the TCA cycle, h...

57. How is the energy released from the breakdown of glucose used by the body? ~ The energy is released during the breakdown of glucose is used by the body to add a phosphate to an adenosine diphosphate molecule and make adenosine triphosphate 58. Describe cellular respiration. ~ During cellular respiration glucose combines with oxygen to form carbon dioxide, water, and ATP 59.

BIO 353 cell bio exam Practice Questions and Answers The break down of glucose into pyruvate releases less than 25% of the total energy present in glucose. The remaining energy is stored in the resulting (2) pyruvate molecules. In the presence of oxygen, acting as an electron acceptor, complete substrate oxidation is possible. ______ is defined as "the oxidation driven flow of electrons, through or within a membrane, from reduced coenzymes to an electron acceptor, usually accompanied by...

why do enzymes need to be regulated? - for the conservation of energy their concentration in cell increases or decreases in response to substrate levels What is the difference between competitive and non-competitive inhibition? - In competitive inhibition, the inhibitor binds directly to the active site, preventing the substrate from accessing it. In non-competitive inhibition, the inhibitor binds elsewhere and either changes the shape of the active site, or steals the metal ions of the enzym...
