Why can we say that production of a GTP is equivalent toproduction of an ATP?

How many GTP molecules are produced in the TCA cycle when you start with a fatty acid molecule that has 18 carbons?

The metabolic pathway responsible for clearing lactic acid from our bodies is called the Cori Cycle. It occurs in the liver, and converts lactic acid back into pyruvic acid, and then into glucose. The glucose can then be used for energy metabolism again. However, the Cori Cycle requires a net input of 4 ATP to operate. Based on this information how can you describe the Cori Cycle? [Select any/all that apply.] Cori Cycle is exergonic. Cori Cycle is anabolc. Cori Cycle is catabolic. Cori Cycle is endergonic.

Why is the process of activation a useful strategy in metabolism?

Medical researchers are studying a patient with the newly discovered u LEKS metabolic syndrome, in which a genetic mutaton prevents NADH produced in the cytosol from being reoxidized by the electron transport chain. Suppose the following nutrient molecule is digested and metabolized by this patient under anaerobic conditions, e.g. during a sudden intense exertion: de HO-CH: -OH Он н. HO H OH How many ATP molecules will uttimately be produced by the catabolism of this molecule? Note: you can ussume the catabohism is as complete as it can be under the conditions given above. How many molecules of pyruvate will be produced during dycalysist How many maleoules of lactate will be produced

The electron-transport chain consists of a number of multi protein complexes, which work in conjunction to pass electrons from an electron carrier, such as NADH, to O2. What is the role of these complexes in ATP synthesis? It has been demonstrated that respiration supercomplexes contain all the protein components necessary for respiration. Why is this beneficial for ATP synthesis, and what is one way that the existence of super complexes has been demonstrated experimentally? Coenzyme Q (CoQ) is not a protein, but a small, hydrophobic molecule. Why is it important for the functioning of the electron transport chain that CoQ is a hydrophobic molecule?

Phosphofructokinase (PFK-1) is one of the most regulated enzymes in metabolism. Based on all of the principles we have learned in this class, which of the following would be most likely to be an allosteric activator of PFK-1?   a Pyruvate   b Acetyl CoA   c Citric acid   d glucose

Which of the following conditions will produce active glycogen phosphorylase? AMP АТР Phosphorylation of Serine 14 Glucose Glucose-6-Phosphate Phosphorylation of Serine 14 and AMP Phosphorylation of Serine 14 and ATP

why is the pathway for biosynthesis of a biomolecule at least partially different than the pathway for catabolism.

Processes taking place in the mitochondrion convert the chemical potential energy of NADH into the chemical potential energy of ATP. A proton concentration gradient (Δ[H+]) is part of this process. Describe exactly where this gradient is located, and how the gradient is produced. In terms of the gradient, where is the higher [H+] and where is the lower [H+]?
