Free Energy

Free Energy changes in glycolysis. a) Which three reactions are irreversible? What does this mean? b) The other seven reactions are near equilibrium. Explain how this diagram reflects this. Please see attached for full question.

Solution

In solution, 80% of the fructose 6-phosphate is in the beta-anomeric form and 20% is in the alpha-anomeric form... Please see attached for full question. It shoud be 2,5 -Anhydro..............(in beta configuration)

I need the answer for this question.

1. The energies of glycolysis shows that there is a large drop in free energy upon oxidation of glycerladehydes 3-phosphate to 1,3-bisphosphoglycerate. in the presence of oxygen, some of this energy is ultimately converted into ATP production. However, no such conversion happens under anaerobic conditions. Explain why? 2. Ho ...continues

enzyme superoxide dismutase and electrostatic potential

SOD is a diffusion-limited enzyme. What does it mean by "diffusion-limited enzyme"? Why will enzyme has electrostatic potential? Where are they from? What's the probable use of the enzyme's electrostatic potential? Is this enzyme related to metabolic pathway? If you have the suggest reading, please give me the link.

Biochem

1. The disease beriberi, which results from a dietary deficiency of vitamin B1 (Thiamine) is characterized by neurologic and cardiac symptoms, as well as increased levels of pyruvate and alpha- ketoglutarate in the blood. How does a deficiency of thiamine account for the increased levels of pyruvate and alpha- ketoglutarate? ...continues

Electron Transport

4. Electron transport translocates protons from the mitochondrialmatrix to the external medium, establishing a pH gradient across the inner membrane (outside more acidic than inside). The tendency of protons to diffuse back into the matrix is the driving force for ATP synthesis by ATP synthase. During oxidative phosphorylation ...continues

1. Since lactate is a "dead end" product of metabolism in the sense that its sole fate is to be converted into pyruvate, what is the purpose of its formation? 2. The molecule 2, 4 -dinitrophenol (DNP) is an uncoupler of oxidative phosphorylation. For a short period of time, it was prescribed clinically as a pill for weight re ...continues
