Summary:
There is a successful electrical connection between a carbon nanotube and hydrogenase. Hydrogenases show as a powerful catalysts. They can be used for hydrogen in fuel cells, which can produce electricity no pollution for motor vehicles, portable electronics, and other devices. Scientist have dound difficulty in putting these enzymes into electrical devices. They do not form good electrical connections. Metals such as platinum are needed to perform. They combined hydrogenase enzymes with carbon nanotubes, submicroscopic strands of pure carbon to make sure that they are good electrical conductors.

Questions:

1. What reactions does this enzyme catalyze? hydrogen in fuel cells, no pollution for motr vehicles, portable electronics, and other devices
2. How is the cell affected if this enzyme is removed?
3. List three things you learned from this article in your own words. These enzymes can be used to decrese pollution in cars. There were difficulties in doing this. It was finaaly fixed whrn they combined other elements.
4. What impact would the absence of this molecule have on the cell? more pollution
