21. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases
Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER
22. Proton transfer across and along biological membranes
Sammanfattning : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. LÄS MER
23. Kinetics of proton and electron transfer in heme-copper oxidases
Sammanfattning : Heme-copper oxidases are transmembrane proteins that are found in aerobic and anaerobic respiratory chains. During aerobic respiration, these enzymes reduce dioxygen to water. The energy released in the reaction is used to transport protons across a biological membrane. LÄS MER
24. K+ channels in the inner ear : electrophysiological and molecular studies
Sammanfattning : Potassium channels are involved in several fundamental cellular processes. Heavy metals, such as mercury and lead, are widespread toxic pollutants and have been shown to act on various ion channels in the central nervous system. LÄS MER
25. Novel Processing and Electrical Characterization of Nanowires
Sammanfattning : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. LÄS MER
