Answer to Problem 15.20UKC
The hydride added to the carbonyl carbon, the polar (C=O) carbon has a partial positive charge, then the reduction process has
Explanation of Solution
Reduction reaction: The given carbonyl molecule is converted into alcohol (b) in this undergoes for reduction process was occurred. The hydride ion added to the carbonyl carbon, because carbonyl carbon is polar it as partial positive charges in carbon atom.
(b)
To determine give the reactions indicate which direction represents reduction and which represents oxidation.

For example, I know that CS2 reacts with amide and sulfhydryl groups on proteins, but what proteins exactly and where are they located?arrow_forward
- What 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_forwardGive examples of balanced redox reactions that match the following:-Catabolic-Anabolic-Oxidative-Reductivearrow_forward
- If 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_forwardAn 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_forward
- Another 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_forwardA particular particle is trying to cross a membrane by simple diffusion from a high concentration of 20mM to a low concentration of 20uM. If a membrane is 15uM in width, and the diffusion coefficient of the particle is 5 uM/sec, what is the influx in uM/sec?arrow_forward
