The truth drug, you cannot lie while you are under its influence.
Sodium thiopental is a barbiturate; these are drugs that act on the gamma-amino butyric acid (GABAa) receptor which decrease neuronal activity. Barbiturates enhance the GABAa receptors, decreasing drastically neuronal activity. It is because of this that overdoses can be lethal. In fact many famous people have died due to overdose on barbiturate-based drugs: e.g. Elvis Presley, Marilyn Monroe, Jimmy Hendrix, and others. The A.U.M., the Japanese terrorist group that in 1995 released sarin nerve gas in the Tokyo subway, is reported to use sodium thiopental on their members to keep them loyal. It is believed that their chief chemist produced 1.7 kg of sodium thiopental.

Sodium thiopental is very well known to moviegoers as the "truth serum". Movies such as Stormbreaker, Meet the Fockers, Kill Bill vol.2, are recent examples of Hollywood's poetic license when it comes to the use of this 'truth serum'. However, sodium thiopental was used by the CIA for many years, and was recently used against Al-Qaeda members to find out secrets within the organization. As mentioned above, it isn't actually a 'truth serum' as such, but it reduces neuronal activity making it harder and harder to think. Using the fact that it is harder for the brain to tell a lie than to tell the truth, sodium thiopental makes the subject dreamily blurt out the truth. But it does not work on people who truly believe in their lies, and therefore is not a reliable source of information.
Competitive inhibitor. It is termed to be an analogue. It is also known to sometimes act as a "catalytic poison".
If an enzyme produces too much of one substance in the organism, that substance may act as an inhibitor for the enzyme at the beginning of the pathway that produces it, causing production of the substance to slow down or stop when there is sufficient amount.
Malonate is a competitive inhibitor preventing the substrate succinate from binding to the enzyme. The structure of succinate is comparable to that of malonate but for the ability for malonate to bind to an enzyme but then cannot further act on it creating a nonproductive complex.
An anaerobic inhibitor act against digestion of some substances.
Bacteria can act as a "enzyme" :)
Sodium benzoate, the well known food preservative has no effect whatsoever on salivary digestion because it wont act on amylase the enzyme present in saliva. But it is known for affecting pepsin and trypsin, the intestinal enzymes.
abscisic acid
A single enzyme molecule can act on about 1000 substrate molecules per second.
All Enzyme are proteins enzymes act as catalyst
Because the enzyme salivary amylase lacks protein.
coenzyme
yes. an enzym IS a protein.
