Elements of the periodic table for medical professionals

Excursus: Metals in enzymes Many enzymes and enzyme complexes contain metal ions in their active center. These include, in particular, all enzymes in the respiratory chain and photosynthesis. Some coenzymes also have metal ions, for example cytochrome c and cobalamin (vitamin B12). In some proteins, metals are needed to stabilize the tertiary structure (e.g.

Applications for heat transport - energy saving house

The energy-saving house was developed to study the processes of heat and energy transfer and to demonstrate the possibilities of remote control. The incident sunlight is converted into electricity and heat by means of a solar cell and solar collector. Various consumers are operated with the electricity and the heat circuit heats the interior of the house.
