C) is performed solely on the glucose ingested by the organism D) is also referred to as the Krebs cycle. E) completely oxidizes glucose to carbon dioxide. 66. Three different metabolic pathways are responsible for the production of ATP. What are they? A) glycolysis, oxidation, and the Calvin cycle reactions B) hydrolysis, active transport, and the light reactions C) glycolysis, the reactions on the electron transport chain, and the Krebs (citric acid) D) E) cycle substrate inhibition, catabolism, and fermentation None of the above is correct. 67. In glycolysis, one molecule of glucose containing six carbons is converted to two Containing three carbons each. This reaction also yields two and two molecules of molecules of molecules of A) lactic acid; Or; acetaldehyde B) pyruvate; ATP; NADH C) acetyl-CoA; ADP; P D) galactose; H2O; ATP E) sucrose; lactic acid; FADH 68. Energy used in cellular respiration can originate from: A) carbohydrates and proteins only. B) carbohydrates only. C) fats only. D) proteins only. E) carbohydrates, proteins, and fats. 69. Which of the following statements about glycolysis is INCORRECT? A) It occurs in the cytoplasm of the cell. B) It requires oxygen. C) It results in the oxidation of glucose. D) It generates ATP E) It leads to the formation of pyruvate.Explanation / Answer
65. Glycolysis occurs in all cells is the correct answer. It can be occured in both aerobic and anaerobic respiration.
66. Glycolysis, electron transport chain, and the Krebs (citric acid) cycle are the processes involved in the production of ATP.
In glycolysis the ATP is produced at substrate level phosphorylation, while the NADH and FADH produced at different steps of krebs cycle and glysolysis are converted to ATP in Electron transport chain by electron gradient formation and oxygen as acceptor of electrons.
67. In glycolysis, one molecule of glucose containing six carbons is converted to two molecules of Pyruvate containing six carbons each. This reaction also yields two molecules of ATP and two molecules of NADH.
68. carbohydrates, proteins, fats can be used for generation of energy in cellular respiration.
69. It requires oxygen is the incorrect statement because glycolysis can occur in absense of oxygen too. It generates less ATP as compared to aerobic glycolysis.
