- Help me understand how carbon disulfide leads to toxicity in the brain, using terms like distal axonopathy, neurofilaments, covalent cross-linking, adducts, etc.,...please intuitively explain what is happening and where and the effects of it. For example, I know that CS2 reacts with amide and sulfhydryl groups on proteins, but what proteins exactly and where are they located?arrow_forwardWhat is the standard free energy change (in kJ/mole) of the spontaneous reaction between Oxygen and NADH to form H2O2 and NAD+?arrow_forwardRedox Chemistry: Give standard free energy changes expected for the following reactions:-Succinate -> fumarate (using FAD/FADH2)-Oxaloacetate -> Malate (using NAD/NADH)-NADH --> NAD+ (using FMN/FMNH2)-CoQ --> CoQH2 (using Cytochrome C)arrow_forward
- Give examples of balanced redox reactions that match the following:-Catabolic-Anabolic-Oxidative-Reductivearrow_forwardIf there are 20uM of a GLUT2 transporter on the surface of a cell, each able to move 8 per second, and 50mM glucose outside of the cell, what is the flux into the cell in mM/sec?arrow_forwardA transporter is responsible for antiporting calcium and glucose. The transporter brings glucose into the cell and sends calcium out of the cell. If blood [calcium] = 2.55mM and intracellular [calcium] = 7uM, blood [glucose] = 5.2mM, and intracellular [glucose] = 40uM, what is the free energy of transport? Assume a membrane potential of 62mV (negative inside).arrow_forward
- An ATP-coupled transporter is used to import 1 phosphate from the extracellular environment. Intracellular phosphate exists at 65mM, while it is 2mM outside.Assume a free energy change of ATP hydrolysis of -42.7 kJ/mol. What is the net free energy change of the coupled reaction? Assume a membrane potential of 70mV.arrow_forwardAnother transporter brings 3 chloride ions into the cell. Outside, chloride has a concentration of 107mM, and 4mM inside the cell. Assuming a membrane potential of 62mV (negative inside), what is the free energy of transport of these ions?arrow_forwardFor the Oxaloacetate -> Malate reaction, assume the normal ratio of NAD/NADH, what is the maximum ratio of Malate/Oxaloacetate that will allow reaction progress?arrow_forward
