a) The enzyme glucose 6-phosphatase is essential for the creation of glucose (which passes from the liver to the blood stream) from pyruvate/glycogen? Choose the right option: pyruvate or glycogen b) Red blood cells lack mitochondria and thus they reduce Pyruvate to Lactate under aerobic/anaerobic conditions. Choose the right option: aerobic or anaerobic c) All enzymes involved in glycolysis are cytosolic. Correct or incorrect? d) The Mg+2 ion is a cofactor of most enzymes that participate in the process of...

Read the following choices and identify the one that is NOT correct. (A) Aerobically, oxidative decarboxylation of pyruvate forms acetate that enters the citric acid cycle. (B) In anaerobic muscle, pyruvate is converted to lactate. (C) In yeast growing anaerobically, pyruvate is converted to ethanol. (D) Reduction of pyruvate to lactate regenerates a cofactor essential for glycolysis. (E) Under anaerobic conditions pyruvate does not form because glycolysis does not occur.

The two molecules of electrons produced in glycolysis can be turned into acids and other products through ____________ . These molecules then bring the ____________ generated by glycolysis and the Krebs cycle to the ____________ embedded in the bacterial cell ____________ . Cell that conduct ____________ respiration utilize free oxygen as a final electron acceptor in this process, while those that conduct ____________ respiration use oxygen-containing ions to create ATP molecules. The Krebs cycle produces a small amount of ATP, but also generates the reduced ____________ NADH and FADH₂. In other...

"In many different species, lactate dehydrogenase (LDH) constitues a major checkpoint of anaerobic glycolysis, by catalyzing the reduction of pyruvate into lactate. This enzyme has recently received a great deal of attention since it may constitute a valid therapeutic target for diseases so different as malaria and cancer. In fact, the isoform expressed by Plasmodium falciparum (pfLDH) is a key enzyme for energy generation of malarial parasites. These species mostly depend on anaerobic glycolysis for energy production, since they lack...

Alcohol dehydrogenase detoxifies ethanol in two steps. First, ethanol is oxidized to acetaldehyde, which is coupled with the reduction of NAD' to NADH. Second, acetaldehyde is oxidized to acetate, which process also produces an NADH molecule. Under anaerobic conditions, muscle cells needing extra energy couple the reduction of pyruvate to lactate with the oxidation of NADH to NAD*. The NAD is then shuttled to the anaerobic glycolysis reactions which produce a small amount of ATP. One common side effect of...
