Electron transfer between redox centers in proteins is controlled by electron tunneling. If we model a bound electron as in a box, if the distance between the redox centers is 0.777 nm and the tunneling constant C = 13.1 nm-1, what is the tunneling coefficient for electron tunneling? Please enter a numerical answer below.

Electron transport chains (ETCs), large proteins through which electrons move, play important roles in two of nature's fundamental processes: (1) the conversion of electromagnetic energy from the Sun into the energy in the chemical bonds in glucose molecules and (2) the conversion of the energy in these glucose molecules into useful forms for metabolic processes, such as muscle contraction, building proteins, and respiration. Respiratory ETCs are located in the inner membranes of mitochondria, the power plants of eukaryotic cells. ETCs...

Problem 2 (20 pts) A scanning tunneling microscope employs a small sharp conducting tip that is brought into close proximity of a material, as TIP shown in the figure at right. The vacuum region between the tip and the sample acts as a potential barrier because the electrons in the material have a lower potential than in free space (work functions of the materials). Therefore, the current across the vacuum is proportional to the transmission probability T approximated by a...

This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
