We covered in lecture that the complete oxidation of glucose (all the way to CO2 andH₂O and "cashed in" via the ETC) could yield up to 32 ATP. However, a moleculedoes not always need to start at glucose to be broken down.Answer the following questions if you started with a single molecule of 1,3-bisphosphoglycerate.23Starting at a single molecule of 1,3-bisphosphoglycerate, how much ATP wouldbe made in glycolysis alone?How much FADH₂ would be produced in the PDC reaction?DalHow much total NADH would be produced from the complete oxidation of 1,3-bPG (re-read the prompt if necessary to consider what complete oxidationmeans)?Using the appropriate ATP equivalents for NADH and FADH2, how much totalATP (and/or ATP equivalents) would the complete oxidation of 1,3-bisphosphoglycerate yield?--DO

There are three essential pathways that carry out the complete oxidation of 1 molecule of glucose.…

Hi can you please answer to those questions explain this to me , if possible giving examples . Thanks A 45 year old man was rushed to the ER after ingesting "Galaxodin," a hypothetical poison. Explain why Galaxodin is toxic knowing that it increases the pH of the intermembrane space of mitochondria! You will need to give a comprehensive explanation of the process of energy conversion starting from NAH ending in ATP under normal conditions. Include details such as the transfer of electrons, the proton gradient, and chemiosmosis, NADH and FADH2, and ATP synthase must be mentioned. The majority of your grade will come from this part. Then explain why Galaxodin is so toxic!

An animal cell, roughly cubical in shape with side length of 10 μm, uses 109 ATP molecules every minute. assume that the cell replaces this ATP by the oxidation of glucose according to the overall reaction 6O2 + C6H12O6 →6CO2 + 6H2O and that complete oxidation of each glucose molecule produces 30 ATP molecules. how much oxygen does the cell consume every minute? How long will it take before the cell has used up an amount of oxygen gas equal to its own volume?

How much fat (in grams) would the body have to burn to produce the daily minimum requirement of 40 kg ATP from ADP and phosphate? Assume that: 1. The fat is metabolized completely to water and carbon dioxide. 2. The energy that is released can be used entirely for ATP production. 3. Complete oxidation of 1 g of fat to water and CO2 releases 9 kcal or 37 kJ. 4. The Delta G for ATP hydrolysis is -30.5 kJ/mol. You will have to look up one more value online to answer this question, but you do not need to know anything about lipid metabolism. A) approx. 16 to 17 g of fat B) approx. 65 to 66 g of fat C) approx 22 to 23 kg of fat D) approx. 267 to 268 g of fat E) approx. 5 to 6 kg of fat
Normally, the flow of electrons to O2 is tightlylinked to the production of ATP via the electrochemicalgradient. If ATP synthase is inhibited, for example, elec-trons do not flow down the electron-transport chain andrespiration ceases. Since the 1940s, several substances—such as 2,4-dinitrophenol—have been known to uncou-ple electron flow from ATP synthesis. Dinitrophenol wasonce prescribed as a diet drug to aid in weight loss. Howwould an uncoupler of oxidative phosphorylation pro-mote weight loss? Why do you suppose dinitrophenol isno longer prescribed?
Which of the following statements about the aerobic respiration of a molecule of glucose is FALSE? O It requires pathways and membrane complexes in both the cytosol and mitochondria in eukaryotes. O 34 molecules of ATP are generated by oxidative phosphorylation. O It requires pathways and membrane complexes in the cytosol and plasma membrane in prokaryotes. O It can generate 38 molecules of ATP in prokaryotes. O 12 molecules of ATP are generated by substrate-level phosphorylation.
1. The citric acid cycle ends with the reaction catalyzed by malate dehydrogenase (MDH) shown below. The product of this reaction, oxaloacetate (OAA), combines with acetylCoA (catalyzed by citrate synthase) to begin the cycle. Given this answer the following questions. All of your work must be shown. R = 8.314 J mol-1 K -1 Malate + NAD* OAA + NADH a. What is the keq of the reaction given that AG" = 30.0 kJ/mol? Assume T = 298K. Please show your work. b. The concentration of malate within a rat mitochondria is about 0.20mM. Furthermore, the ratio of [NAD+]/[NADH] is around 10/1. Given this calculate the concentration of OAA within the mitochondria considering that the MDH reaction is at equilibrium under mitochondrial conditions. c. Citrate synthase catalyzes the first step in the CAC as shown below. Determination of its actual free energy change is difficult for a number of reasons however most scientist will point to the fact that it is negative. Let's assume AG = -5.0 kJ/mol. The…
