Your best bet would probably be the Pyro, because he can spray flames, and most of the time when he has ignited his enemy, the Pyro can run away, and his enemy will die due to the fire alot of times.
Chemical reactions slow down in the cold. The electricity produced in a car battery is the result of chemical reactions between the sulfuric acid and the lead plates. Slow down those reactions and the battery is not able to produce its normal current.
yes they can
are enzymes carbohydrates
No, they speed them up by lowering the activation energy of reactions. The body has other ways to slow reactions. Concentration of enzymes, inhibition of enzymes, sometimes by negative feed back mechanisms.
Inhibitors slow down chemical reactions. Catalysts speed up reactions.
inhibitors
Catalyst speeds up reactions, and inhibitors are used to slow down reactions.
No, but control rods do.
In biological chemical reactions, examples of these are called enzyme inhibitors. Enzymes speed up reactions, but enzyme inhibitors slow them down. This can be by either competing with the reactants for a spot on the enzyme, or by altering the enzyme's structure so that it does not speed up reactions anymore. In either case, enzyme inhibitors slow down chemical reactions.
The light reactions would slow down.
Chemical reactions involving enzymes slow down when the temperature is too high or too low, as enzymes have an optimal temperature range for activity. Additionally, changes in pH levels can also affect enzyme activity, causing reactions to slow down. Lastly, the presence of inhibitors or competitive molecules can hinder enzyme function, leading to a slowdown in reactions.
oxygen+water=rust sory I don't have that much.
