A metal based tooth for a bridge is definitely stronger than just porcelain, but depending where the bridge is in the mouth, it may not be as aesthetically pleasing as just porcelain would be.
Porcelain is a ceramic material, and because of this, the question "devolves" into something akin to, "Is a ceramic light socket better than a ceramic one?"
The durability between ceramic and porcelain tiles is that porcelain tires are more dense and are considered more durable and better suited for heavy wear than the ceramic tiles.
porcelain has affected us because we have better things to eat and drink with than paper plates and plastic cups
Depends on how much substrate the enzyme can process. Most enzymes can process more than one molecule of substrate without denaturing or becoming unusable. However, in the terms of your question. More substrate is better. Too many enzymes would mean the reaction would be cut short, because they would all react the substrate at once. So for a prolonged, efficient reaction more substrate would be proper.
An induced fit is a change in the shape of an enzyme which allows it to react effectively with a substrate. The reason for the alteration is to speed up a chemical reaction.
Neither actually, they are not supposed to be subjected to open, intense heat. But, of the two, ceramic would be better.
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.

Actually, porcelain veneers are a great way to fix a number of problems with your teeth! Porcelain veneers can protect damaged teeth, fix chipped teeth, and even "close" gaps and "straighten" your teeth. Of course, it would be optimal to not need veneers at all - but if you have a situation that calls for veneers, they are an excellent option (especially porcelain veneers, as they do a much better job emulating the look of natural teeth than resin veneers).
induce fit model is better because it causes a change in the enzyme active sit and allows the substrate to fit in
