Explain how the fructose 2,6-bisphosphate regulates the balance between glycolysis and gluconeogenesis. How does this ensure that both processes do not occur at the same time in the same cell? How is glucose broken down in yeast and why does it produce a high amount o...
Pyruvate is the first molecule in the Kreb's cycle, where does it come from? What is the yield of ATP from the complete aerobic catabolism for Fructose-1,6-bisphosphate? What is the net yield of ATP when each of the following substrates is completely oxidized to CO2 via glycolysis, the ...
Pyruvate kinase activity is most broadly regulated byallosteric effectors, covalent modifiers and hormonal control. However, the most significant pyruvate kinase regulator is fructose-1,6-bisphosphate (FBP), which serves as an allosteric effector for the enzyme. What is PK illness? Pyruvate kinase (P...
“Chemical” RNs are directed hypergraphs with a stoichiometric matrix\mathbf {S}whose left kernel contains a strictly positive vector and whose right kernel does not contain a futile cycle involving an irreversible reaction. This simple characterization also provides a concise specification of random mo...
These comprised secreted phosphoprotein 1, fructose-bisphosphate aldolase, and malate dehydrogenase 1 [104]. In contrast, glutathione peroxidase and triosephosphate isomerase were enriched in samples with higher straight-line velocity values. In a study involving stallion semen that is or is not tolerant...
(monomer, dimer, tetramer, cluster, agglomeration), binding to other structures such as membranes and the cytoskeleton, environmental conditions (temperature, pH, and redox conditions, and allosteric factors including ATP, citrate, fructose 2,6-bisphosphate (F2,6BP), fructose 1,6-bisphosphate (F1,...
The majority of these expressed proteins were involved in glycolysis (enolase, fructose-bisphosphate aldolase, glyceraldehyde-3-phosphate dehydrogenase, L-lactate dehydrogenase, 6-phosphofructokinase, glucose-6-phosphate isomerase, phosphoglycerate kinase, phosphopyruvate hydratase, pyruvate kinase, triosephosphate...
What effect will low fructose-2,6-bisphosphate and high ATP have on glycolysis? a. It will shut glycolysis down at the step of triose phosphate isomerase. b. It will shut glycolysis down at phosphofructokinase. c. It will speed up glycolysis by activating ...
If the intracellular concentration of fructose 1,6-bisphosphate at equilibrium (delta G = 0) was 10 MM, what would be the predicted concentration of the products? How well does an equilibrium model represent stream ecosystems relative to lake and groundwater ecosystems?
What is adenosine triphosphate (ATP)? What role does it play in the body? Describe how energy is stored in an ATP molecule? In an erythrocyte undergoing glycolysis, what would be the effect of a sudden increase in the concentration of: a. ATP? b. AMP? c. fructose-1,6-bisph...
