Pyruvate:Pyruvate is a molecule that is generated at the end of glycolysis. Pyruvate may be fermented or oxidized depending on the availability of oxygen.Answer and Explanation: In the cell, pyruvate oxidation occurs when pyruvate enters the mitochondria. As pyruvate enters the mitochondria, it ...
Why does lack of oxygen result in the halt of ATP synthesis? Why does pyruvate require active transport? What is characteristic of reactions in which FAD rather than NAD+ is involved? Why does lipid catabolism produce more ATP? Why is a different enzyme involved in each step of glycolysis?
What stage(s) of cellular respiration require(s) an input of ATP? A. Glycolysis B. Pyruvate Oxidation C. Citric Acid Cycle D. Electron Transport Chain E. All of the above require an input of ATP Which Steps in cellular respiration use oxidative phosphorylation to prod...
These results, suggesting that the mitochondrial generation of reactive oxygen species is not required for cell death following exposure to hyperoxia, are consistent with those of Senturkeret al. (38), who demonstrated that apoptosis following administration of VP-16 and cisplatin did not require ROS...
If there is no O2 in the mitochondrion, what process stops first? a. pyruvate oxidation. b. oxidative phosphorylation. c. Krebs Cycle d. glycolysis. e. active transport of ATP. In glycolysis, how is phosphofructokinase-1 inhibited by ATP by both allosteric regulation and feedback inhibition?
Consider a yeast cell that has formed pyruvate through the action of glycolysis. If this yeast is well supplied with oxygen, what will be the fate of this pyruvate? (a) It will be converted to lactate (b) It will be converted to ethanol (c) It will be ...
B. Carbon dioxide + Water + ATP to Sugar + Oxygen. C. Oxygen + Carbon dioxide to Sugar + Water + ATP. D. Water + ATP to Carbon dioxide + Sugar. Which process of aerobic respiration produces the majority of ATP? a. Pyruvate oxidation b....
Where is pyruvate made in the cell? Why is phosphorylation important? Does fermentation occur in glycolysis? What is glycolysis? What happens to glycolysis if oxygen is not present? What metabolic pathway in fermentation produces ATP? What does chemiosmosis produce?
Which Steps in cellular respiration use oxidative phosphorylation to produce ATP? A) Glycolysis B) Pyruvate oxidation C) Kreb's cycle D) None of the above (which one) Describe the control mechanism of cellular respiration as it pertains to the Krebs cycle?
What are the products of pyruvate oxidation? When the mitochondria lack adequate oxygen during activity, what product is formed from pyruvate? Which part of cellular respiration breaks down glucose into pyruvate? What is the Krebs Cycle? Why...
