Well, well, well, when a protein like an enzyme gets hot and bothered, it can undergo a process called denaturation. This basically means it loses its shape and can't do its job properly, like a soggy noodle trying to hold up a meatball. So, too much heat can essentially render the poor enzyme useless, like trying to use a melted ice cream cone as a spoon.

How does heating a enzyme affect its function?
For an enzyme to work it must bind to a specific substrate molecule, using a part of the enzyme molecule called the active site. To do this, the enzyme's active site and the substrate must have matching (complementary) shapes. The shape of an enzyme molecule depends on the exact way in which the molecule folds up. When enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule "unwinds" into a random shape. It can no longer bind with its substrate so it no longer has any activity. This "unwinding" of a protein molecule is called denaturation.
What is the pH in enzymes activity?
pH is a major determinant of protein structure. The function of a protein is directly related to its structure. For example, pepsin (a proteinase- a protein-digesting enzyme) is functional in the low pH of the stomach because the pH of the stomach provides a suitable environment for proper folding, interactions, and the overall shape of the protein. In the small intestine, where the pH is much higher, it has a significant decrease in activity because this is no longer a favorable environment for the protein.
Does enzyme is a protein that acts as a catalyst?
Yes, enzymes are proteins that act as biological catalysts, speeding up chemical reactions within cells by lowering the activation energy needed for the reaction to occur. This allows biochemical reactions to happen at a much faster rate than they would without enzymes.
What is meant by non-redundant protein?
Redundant protein is a term used in bodybuilding where the person takes so much protein, some of it can't be used by the body. Non-redundant protein refers to the protein which is actually used and absorbed by the body. This term is also used when referring to enzyme biology for when the substrate is protein.

What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
What is the effect of heat on enzymes?
Heat can denature enzymes, causing them to lose their shape and therefore their function. At low temperatures, heat can increase the rate of enzyme activity, but at high temperatures, enzymes can become inactive due to the disruption of their protein structure.
Can the active site of an enzyme be damaged at very high pH levels?
The active site of an enzyme can very much be influenced and damaged by a very high pH level. An enzyme is a protein, and because of that it is very sensitive to pH levels. High pH can denature a protein, and thus "damage" the active site.
Can all diamonds become graphite overtime?
Diamond is a form of carbon which has been subjected to heat and pressure. I don't think you can reverse the reaction. Much to the dismay of insurance companies diamonds reverts to carbon dioxide when subjected to extreme heat: a furnace will do it.

What happens to the activity of an enzyme on either side of its temperature optimum?
Lower temperature: The energy input increases the flexibility of bonds in proteins. Higher temperature: Too much energy makes the bonds between the proteins brake and the protein unfolds 'denatures'
How does an enzyme become denatured?
An enzyme becomes denatured when: A) the temperature exceeds the optimum temperature for that enzyme (ie the temperature that it works best at) B) the pH of the surrounding of the enzyme is too low or too high for the optimum pH for that enzyme. When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape becomes broken. The enzyme shape changes and the substrate no longer fits in to the active site. An enzyme which has become denatured is permanently inactive and will take no further part in reactions.

Lock and key method?
In biology the lock and key method states that an enzyme and it's substrate are complementary and only the correct substrate can bind with the enzyme, this is due to the folding in the protein structure. However this theory is outdated and the inducted fit method is a much better representation.
What is the major difference between how oil and coal are formed?
Oil is formed from the remains of marine plants and animals that have been buried and subjected to high heat and pressure over millions of years. Coal, on the other hand, is formed from the remains of land plants that have been buried and compacted over time without being subjected to as much heat and pressure as oil.
