Why is the citric acid cycle considered to be a “central metabolic hub” of the cell?...

Why is the citric acid cycle considered to be a “central metabolic hub” of the cell? Provide an explanation with specific examples, including control and regulatory aspects of the citric acid cycle. What happens when there are "defects" in the citric acid cycle? Provide examples

Which of these is NOT a product of the citric acid cycle?

Which of these is NOT a product of the citric acid cycle? CO2 FADH2 NADH + H+ acetyl CoA ATP

Which of these enters the citric acid cycle?

The relative metabolic activities in an organism of glycolysis + the citric acid cycle versus pentose...

The relative metabolic activities in an organism of glycolysis + the citric acid cycle versus pentose phosphate pathway + gluconeogenesis can be measured by comparing the rates of 14CO2 generation upon administration of glucose labeled with 14C at C (1) with that of glucose labeled at C (6). Explain by justifying your answer what pathway is responsible for the loss of C1 and C6 of glucose

inThe citric acid cycle there are three reactions of the citric acid cycle it's self that are regulated: -citrate synthase which is where ATP inhibits in in citeo -isocitrate dehydrogenase: alosterrically activated by Ca2+ and ADP also is inhibited by NADH - alpha ketoglutarate dehydrogenase which is where Ca2+ increases the rate of formation of succinyl-CoA what would happen if all three of these reactions were not present? what would happen if citrate synthase was not functioning, what would happen...

Energetics. We have learned that all metabolic pathways must be thermodynamically downhill. How can the citric acid cycle work even though the ∆G°’ of the last reaction is > 0? Explain the relevance, if any, of the order in which endergonic and exergonic steps occur within a metabolic pathway.

Step 2 of the Citric Acid Cycle converts citrate to isocitrate. This moves the functional group (-OH) to convert a ______________alcohol to a _____________alcohol, which can then be oxidized to an a-ketone in the next step along with a decarboxylation reaction. Write the molecular formula for citric acid (citrate with the hydrogens put back on those carboxyl groups): ___________________ From the molecular formula, calculate the molar mass for citric acid:_______________g/mol. How is citrate related to isocitrate? a. They are constitutional...
