- Glycolysis results in the production of two ________ molecules from a single molecule of glucose. In the absence of ________, the end product of glycolysis is ________. acetyl CoA, pyruvate, lactate ATP, carbon, pyruvate pyruvate, oxygen, lactate pyruvate, carbon, acetyl CoAarrow_forwardIn 2012, an Illinois man was killed by cyanide poisoning after he won a million dollars in the lottery. Cyanide is a lethal poison because it interferes with the electron transport chain in mitochondria. What effect would cyanide have on cellular respiration? (a) Glycolysis, the Krebs cycle, and oxidative phosphorylation would all be inhibited. (b) The Krebs cycle would be inhibited, but oxidative phosphorylation would not. (c) Oxidative phosphorylation would be inhibited. (d) Glycolysis, the Krebs cycle, and oxidative phosphorylation would all be stimulated.arrow_forwardQ20. Evolutionary biochemists think that glycolysis represents a very ancient metabolic pathway. Which of the following would be evidence in favour of this claim? A. Glycolysis can operate without enzymes B. Glycolysis does not require ADP C. Glycolysis is not dependent on O2. D. Glycolysis does not generate CO2.arrow_forward
- Why is oxygen important in aerobic cellular respiration? a. Without oxygen, the Citric acid cycle will be disrupted b. Oxygen is the final electron acceptor during the electron transport chain c. they produce carbon dioxide and water d. It provides electrons during cellular respirationarrow_forwardand incorporated inside a molecule. Which? a) ATP beautiful c) pyruvate d) carbon dioxide 8- A) What process is typical of a cellular respiration transition reaction? B) What process takes place in the cytoplasm? a) A: pyruvate converted to acetyl-CoA B: glycolysis b) A: production of citric acid B: glycolysis c) A: glucose converted into two molecules of pyruvate B: electron transport chain d) A: production of water from oxygen (O2) B: Krebs cyclearrow_forwardConsider Model 1. Besides ATP, what other molecules appear to be high potential energy molecules (free energy carriers) during cellular respiration? Justify your answering with evidence from the model.arrow_forward
- Life requires energy. In a short essay (100–150 words), describe the basic principles of bioenergetics in an animal cell. How is the flow and transformation of energy different in a photosynthesizing cell? Include the role of ATP and enzymes in your discussion.arrow_forwardUse this analogy "A baker starts with a bowl of dough and eventually turns it into all sorts of goodies" to explain the events of the Krebs Cycle and the Electron Transport Chain. It's important to break down every single reaction present in cellular respiration.arrow_forwardYour body produces lactic acid under anaerobic conditions. What is the purpose of your body producing lactic acid? Select one: a. Lactic acid serves no purpose other than to regulate NAD+. b. Lactic acid combines with co-enzyme A, and then enters the citric acid cycle once O2 becomes available. c. The purpose of Lactic acid is the increase acidity in your blood. d. Lactic acid is utilized as a fuel source by our muscles.arrow_forward
- a) What carbon-containing molecule exits the citric acid cycle? Why doesn’t your body capture the carbon-containing molecule you identified in part (a) and use that molecule to build new sugars and fats? Explain your answer. You have just created a new enzyme that will make the citric acid cycle more efficient! Instead of the citric acid cycle taking 8 steps, all of the bonds between the carbon atoms will be broken in only one step! Is this a good idea? Explain your answer.arrow_forwardExplain the relationship between food consumption and cellular respiration. How does the food we eat generate ATP energy? Make sure to discuss ATP synthase in the electron transport chain.arrow_forwardMatch the parts of cellular respiration to their associated activities. (1) electron transport chain (2) glycolysis (3) citric acid cycleA. glucose molecules are broken down into pyruvic acid B. the final electron acceptor is oxygen C. acetyl CoA molecules are broken down to release CO2 and high-energy electronsarrow_forward
