The citric acid cycle is a unique metabolic pathway because it is cyclic. Which statementBEST describes how it is cyclic?It is cyclic because oxaloacetate is regenerated.It is cyclic because CO2 is regenerated.It is cyclic because it is linked with oxidative phosphorylation.O All of the above are reasons that the citric acid cycle is cyclic.

Lactate dehydrogenase catalyzes the following equilibrium reaction in both liver and muscle cells: pyruvate+NADH+H+lactate+NAD+ In terms of equilibrium, explain why lactate must be removed from muscle cells under anaerobic conditions and why lactate does not accumulate in the liver under these conditions. Hint: Think of the Cori cycle.
The oxidation of 1 mol of glucose supplies enough meta-bolic energy to form 36 mol of ATP. Oxidation of 1 mol of a typ-ical dietary fat like tristearin (C₅₇H₁₁₆O₆) yields enough energyto form 458 mol of ATP. (a) How many molecules of ATP canform per gram of glucose? (b) Per gram of tristearin?
Give an example of a coupled reaction showing an overall change in free energy.
. Each gram of mammalian skeletal muscle consumes ATP at a rate of about 1x 10-3 mol/min during contraction. Concentrations of ATP and creatine phosphate in muscle are about 4 mM and 25 mM, respectively, and the density of muscle tissue can be taken to be about 1.2 g/cm'. (a) How long could contraction continue using ATP alone? (b) If all creatine phosphate were converted into ATP and utilized as well, how long could contraction continue? (c) What do these answers tell you?
A series of chemical reactions convert a polypeptide into 13 acetyl COAS. This acetyl CoA goes into the citric acid cycle and then all of the NADH and FADH2 produced are covnerted to ATP by oxidative phosphorylation. How måny total ATP is produced from this acetyl CoA including the citric acid cycle and oxidative phosphorylation? Your Answer: Answer units
Give an account of the total ATP yield when I molecule of glucose is converted to carbon dioxide and water?
ATP Synthase in plants has the same basic structure and function as the ATP Synthase in humans. O True O False
All three answer plz
Anaerobic glycolysis (i.e., lactic acid fermentation) produces pyruvate that is then converted to lactate through the activity of lactate dehydrogenase. The conversion of pyruvate to lactate would seem to be an unnecessary step, since this process does not result in any further release of energy. Explain the necessity for the production of lactate as the endpoint for anaerobic glycolysis.
Answer True or False The Na/K-ATPase pump is an example of a coupling element between a spontaneous process and a non spontaneous process.
Which of the following four general statements is TRUE regarding oxidative phosphorylation (otherwise known as the electron transport chain)? Oxidative phosphorylation . 3 of these 4 responses are correct is the metabolic process where most of the cell's glucose is produced occurs along and within the innermost membrane of the mitochondria requires oxygen (02) in a very early stage of the process uses only the NADH produced in glycolysis (and not the Krebs (or citric acid) cycle) to produce ATP
At what point in photosynthesis is the proton motive force generated? in the light harvesting complex of photosystem I| as electrons are passed to the enzyme NADP+ reductase as electrons move between photosystem II and photosystem I in the Calvin cycle O as electrons are passed to the primary electron acceptor
