Although we study the citric acid cycle as the final stage oxidation of carbon from glucose, an in-depth look at the cycle shows intermediates entering and leaving the cycle from a number of metabolic pathways. with all of these demands on the cycle, how does it maintain a minimal level of oxaloacetate (oaa) to allow the cycle to function? a-oaa can be formed by the condensation of two moles of acetyl coa and occurs when the energy charge of the cell is high. b-the rate of the cycle is increased when the cell has high levels of nadh. c-isocitrate dehydrogenase is allosterically inhibited by adp, which signifies the need for more energy. d-oaa is formed directly via the deamination of glutamate. e-oaa is synthesized via pyruvate carboxylase in an anapleurotic reaction that occurs when acetyl coa is present, such as from fatty acid breakdown

How did the research presented in the article affect scientists' understanding of the evolution of eukaryotes

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off

(6.02 mc)what affect do marine protected areas have on environmental quality? they increase environmental quality by preventing resource overuse. they increase environmental quality by adding new species. they decrease environmental quality by removing all human activity. they decrease environmental quality by adding recycling facilities.
