During the transfer of two electrons from NADH to O2, protons pumped across the membrane to establish the electrochemical gradient. The amount of energy from previous problem consumed for maintaining membrane potential deltaY and gradient of protons across the membrane. Calculate the ratio of proton concentrations across the inner mitochondrial membrane, if the membrane potential was measured at 37 degrees C to be deltaY= 2.0 V.

Expert Solution

This question can be solved by using the Nernst equation.

During the electron transport chain, proton(H+)gets transfered from the mitochondrial matrix to the intermembranal space creating a proton concentration gradient. A membrane potential is maintained across the membrane.

Imagine a scenario is which 104 protons are pumped across the membrane of the inner mitochondrial membrane. If you assume that the glycerol-3-phosphate shuttle is used, and the overall yield of substrate-level phosphorylations is 5, Describe what role the electrons play and describe the general movement of the electrons through the electron transport chain to the final electron acceptor. (5 pts) What would the effect of adding dinitrophenol (DNP) be on the electron transport chain? Be specific. (3 pts) How...

Imagine a scenario is which 52 protons are pumped across the membrane of the inner mitochondrial membrane. If you assume that the glycerol-phosphate shuttle is used, and the overall yield of substrate-level phosphorylations is 3, a. What specific starting molecule in the metabolic pathways we studied would you start with to give such a yield of pumped protons and substrate level phosphorylations? b. At what specific reactions (give the reaction, not just a “number”) in the metabolic pathways would you...

Given your answer for how many protons are pumped by NADH and knowing that 1 ATP...

Given your answer for how many protons are pumped by NADH and knowing that 1 ATP requires 4 H+, how many ATP equivalents of energy can be provided by NADH? Note that I said "equivalents" which means you can have a fraction of ATP here. Round to 1 decimal place.Now make the same calculation for FADH2. Again, make the same assumptions.

. During droughts, water for irrigation is pumped from the ground. When ground water is pumped excessively, the water table lowers. In California, lowering water tables have been linked to reduced water quality and sinkholes. A particular well in California’s Inland Empire has been monitored over many years. In 1994, the water level was 250 feet below the land surface. In 2000, the water level was 261 feet below the surface. In 2006, the water level was 268 feet below...
