1. Uptake Hydrogenase
1) Definition of Uptake Hydrogenase and Mechanism of Hydrogen Production
Uptake hydrogenases are Ni-Fe enzymes that catalyze the conversion of hydrogen gas to hydrogen ions and electrons. They are found in the heterocysts and not in the vegetative cells of nitrogen-fixing strains of cyanobacteria. They remove the hydrogen gas produced by nitrogenase when they carry o
carbon nanotubes reach the lungs, they are much more toxic than carbon black and can be more toxic than quartz, which is considered a serious occupational health hazard in chronic inhalation exposures.
• If fine NT dusts are present in a work environment, exposure protection strategies should be implemented to minimize human exposures.
Strong chemical and materials hygiene.
