Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

WHAT DO YOU CALL A KING'S
FART (
Methane, CHa, is the main component of natural gas. Natural gas is a popular fuel for generating electricity
in power plants and heating homes. If you have a gas stove, it may operate on methane or propane.
Methane is a cleaner fuel than many other hydrocarbons because it produces less carbon dioxide per unit
of heat or thermal energy as it combusts. In its liquid form, it is used as rocket fuel.
Methane is also produced in the human gut during digestion. As it passes through the digestive tract, it
collects at the lower end and is emitted as flatulence or a fart. The hydrogen and methane in flatulence are
of course, flammable. About 10% of a fart is composed of methane. The other gases include hydrogen,
nitrogen, oxygen, and carbon dioxide. Most of the gas emitted by humans in this way is nitrogen and
carbon dioxide that was ingested in swallowing food and drinks.

If a fart is smelly, it isn't the methane. It's the presence of hydrogen sulfide, a gas with the distinct odor of rotten eggs. The,
chemical composition and thus odor of farts differs according to your health and diet, so you would expect a vegetarian's farts to
smell different from those produced by a person who eats meat. Hydrogen sulfide is added to natural gas used in homes for heat
and fuel so that we can smell a leak as it occurs.
The average human fart contains .00643 g of methane gas.

only 10% of it is methane. What mass of water could be generated by ignition of these methane emissions for

Transcribed Image Text:But the problem is bigger than this. Cows and other ruminate animals like sheep and goats are primary sources of dairy
and meat in the U.S. and they have so much trouble digesting grass that they have additional stomachs to aid in
processing it.
A 1995 study of methane emissions from cattle found that cows typically lose about 6 percent of their ingested energy
as methane, partly a result of their slow digestive process. A single cow can produce between 250 and 500 liters, or
about 66 to 132 gallons, of methane a day (the average U.S. vehicle gas tank can hold about 16 gallons of gas).
About 90% of the methane a cow produces is in the form of a belch. The remaining 10% in the form of farts.
