The transport of ions across cell membranes is a key part of the processes of generation and conduction of action potentials in neurons. a) Why do ions require an integral membrane protein in order to pass across neuronal cell membranes? Briefly discuss the specific ion channels and transporters that are involved in the generation and conduction of a neuronal action potential, and indicate whether the protein is involved in facilitated diffusion or active transport of ions. How does myelination of...

Q2 Consider a solar cell made of semiconducting nanocrystals with a bandgap energy of Wg = 0.67 eV. Determine the theoretical efficiency when the solar cell is exposed to the radiation of a 6000-K black body? Assume that photons with less than 3.3 Wg create each one single electron/hole pair and that those with more than 3.3 Wg create 2 electron/hole pairs each owing to impact ionization. [50 marks]
