- The figure above depicts the biochemical pathway involving synthesis of cholesterol. Excess precursors, like acetyl CoA, could lead to overproduction of cholesterol. Once there is an excessive production of cholesterol, certain cardiovascular risks could amplify. In the management of excess cholesterol production, do you think that targeting this pathway would provide a clinical value? Why, or why not?arrow_forwardA new energy drink in stores contains no sugar, carbs or fat. It does, however, contain relatively high concentrations of B-vitamins (B-3, B-5, B-6, and B-12) which our digestive system does not break down. If our useable energy (ATP) is supplied by cellular respiration, where would the energy this products claims to provide come from?arrow_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_forward
- You are studying energy production and metabolic activities of prostate cancer cells in the lab. You compare energy metabolism in these cancer cells with normal cells. Which of the following would you observe? Select all that apply Oxidative phosphorylation is reduced in cancer cells compared to normal cells Glycolysis is reduced in cancer cells compared to normal cells Oxidative phosphorylation is enhanced in cancer cells compared to normal cells Glycolysis is enhanced in cancer cells compared to normal cellsarrow_forwardC6H1206 is oxidized and 02 is reduced. QUESTION 17 Cellular respiration is composed of several different stages. a) Name the different stages. b) What is the purpose of each stage to cellular respiration c) What comes in and what comes out of each stage?

(Hint:think about glycolysis, pyruvate processing, and electron transport chain and what's being inhibited in each) What would happen if this feedback inhibition were removed?arrow_forward
- I have a project to construct a poster with the pathways that we have discussed in class which include glycolysis to beta-oxidation of fatty acids that are depicted inside a cell. I need to include reactions that are regulated, ones that produce or consume energy, and those at branch points between pathways. I also need a list of regulated enzymes and what regulates them. I also need to include intracellular membranes and locate reactions in the appropriate subcellular location. I can only include each metabolite once per subcellular location and include transporters. Any information that can be given to me on the different pathways and reactions would be helpful. I am at a loss and could use some help figuriong out what to put on my project. Thank youarrow_forwardEnergy production pathway is targeted by drugs in the malignent cancerous cells to control an x cancer type. Use your speculation and tell targeting and destroying which one energy producing agent of the oxidative phosphorylation will be most effected in blocking most of the energy production and why?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
- metabolize aerobically and anaerobically. refers to pathways that take place in the presence of oxygen. refers to pathways that are the exact opposite, and occur without the use of oxygen. aerobic and anaerobic, to meet demand during different intensities and durations of exercise. .. a high-energy molecule stored in muscle cells, transfers its high-energy phosphate group to to form ATP. is available, several major metabolic pathways take place and together these steps are called This pathway generates a amount of ATP. the production of a amount of ATP from glucose occurs and this There are three different energy pathways, muscles' The next two pathways involve the carbohydrate If If oxygen is process is called TROUSEarrow_forwardIn this chapter you learned that cellular respiration is a lengthy metabolic pathway that consists of 4 distinct phases, beginning with glucose and ending with 36 ATP molecules. The diagram below illustrates how certain compounds from the breakdown of all nutrients (proteins, carbohydrates, and fats) can be converted into intermediates in głycolysis and the Kreb's Cycle and how they can enter and leave at many different stages of these pathways. Use the lettered items below to corredly identify the numbered items (106 to 115) in the diagram. Record your responses onto the Google Form. food stage 1: a. proteins breakdown of large macro- molecules to simple subunits 106 107 108 b. co2 109 110 fatty acids and glycerol с. lipids stage 2: 111 breakdown of simple subunits to acetyl CoA accompanied by production of limited ATP and NADH d. Kreb Cycle pyruvate simple sugars g. glucose 112 f. ATP 113 02 g. stage 3: complete oxida tion of acetyl COA to H0 and coz involves production of much NADH,…arrow_forwardUse this analogy "A car uses gasoline, which is broken down into energy that propels it forward" 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_forward
