9. The scanning-tunneling microscope works on the principle of electron tunneling. Imagine you are trying to optimize your scanning tunneling microscope. Your microscope has a gold tip (work function 5.1 eV) and your electron has a kinetic energy of 4.6 eV (a) If you move the tip to sample distance from 0.3 nm to 0.2nm how does the transmission probability change? (b) You have a "brilliant" idea. What if you use protons instead of electrons? How will the transmission probability...

Many biological e¯ transfer events are based on the quantum tunneling mechanism (e.g. as the e¯ transfers in the mitochondria or chloroplasts membranes). For a certain combination of e¯ donor and acceptor (co-factors), the rate of e¯ tunneling is given by eq 9.11 (the Text) with k=7 1/nm. By what factor does the e¯ tunneling rate decrease as the distance between the two co-factors change from 1.0 nm to 2.0 nm?

A quantum-mechanical effect called "tunneling" is important in electron transfer processes in biology. Quantum effects are thought to be important in other biological processes as well. First: research "quantum tunneling." Read a basic (Wikipedia-level, e.g.) description to obtain an intuitive grasp of what quantum-mechanical tunneling Then: research "quantum effects in biology." Any article on this topic is likely to include some discussion of electron transfer in photosystems; find a source that includes some discussion of other processes as well. Find...
