The conversion of pyruvate to lactate is important because It is a step in gluconeogenesis. It...
3 20 The conversion pyruvate to either ethanol or lactate occurs A. when there is an abundance of pyruvate but a deficiency of onygen B. when there is an abundance of BOTH pyruvate and oxygen C. when there is a deficiency of BOTH pyruvate and oxygen D. for the regeneration of NADH so that hydrolysis of ATP can continue to fuel the glycolysis pathway Explain how gluconeogenesis differs from gtycolysis 21 Gluconeogenesis is simply the reverse of all 10 steps...
12) Consider the conversion of pyruvate to lactate. Which statement is TRUE? OO OH 0 + CHU - C-CH0 pyruvate CH = CH-CH0 lactate a) It is the preparatory step to the creation of acetyl CoA and the release of CO2 b) It is the isomerization that allows glycolysis to occur (→ CH.CHOH + CO2). e) It is the only way to consume electrons under anaerobic conditions. d) It is a "fermentation step which makes ethanol as an alternative fuel....
| ATP hydrogen lactate oxygen water anaerobic fermentation NAD+ aerobic pyruvate but may continue in 10. The complete breakdown of glucose requires anaerobic conditions through the process of formed by glycolysis accepts two 11. During this process, the atoms and is reduced to 12. This reaction regenerates which can then pick up more electrons to keep glycolysis and production going conditions, like when we 13. Fermentation is a way to produce ATP during use our muscles rigorously.
The last step of glycolysis converts phosphoenolpyruvate to pyruvate. phosphoenolpyruvate + ADP " pyruvate + ATP A G = -33 kJ/mol (-7.5 kcal/mol) The AG" of the reverse reaction is +31 kJ/mol (+7.5 kcal/mol). Instead of reversing the pyruvate kinase reaction, the step is bypassed in gluconeogenesis. Several steps for the conversion of pyruvate to phosphoenolpyruvate via gluconeogenesis are given. Place the steps in the correct order. You will not place all of the steps. First step
The figures below show the two different types of anaerobic respiration: alcoholic fermentation (left) and lactate fermentation (right). Read the descriptions in the table that follows, and then select whether each statement describes alcoholic fermentation, lactate fermentation, or both. Check all that apply.

8. Draw the overall coupled reaction showing the conversion of pyruvate into acetyl CoA. dono STEP 2 nach do not ww what are true. Ir raise, change one word in the statement so that it is true. a. The pyruvate produced from glycolysis must be consumed in some way or glycolysis stops. b. Glycolysis produces ATP directly. too C. Glycolysis breaks down glucose into acetyl CoA. d. Glycolysis is aerobic
14. Lactate dehydrogenase (LDH) catalyzes conversion of pyruvate into L-lactate in muscle tissue. What is the AG' (in kJ/mol) for the forward reaction catalyzed by LDH at an average adult body temperature of 37 °C? Equilibrium concentrations of the reactants and products are given below for each of the components. You must show your calculations.

In skeletal muscle under anaerobic conditions, pyruvate is further reduced to lactate. What is the net equation for the payoff phase of glycolysis? glyceraldehyde-3-phosphate + 2 ATP + Pi ---> lactone + NAD+ glucose+2ATP ---> 2Glyceraldehyde-3-Phosphate + 2ADP + 2H+ 2glyceraldehyde-3-phosphate + 4ADP + 2Pi >2Lactate + 4ATP None of the above
