Only certain molecules can fit into the active site of the enzyme.
Because they have a site on them that is a recognition site for the substrate, and only that substrate or substances that "look like it" will bind to the enzyme.
Yes
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else. Enzymes catalyze or help a reaction take place. They bind substrates and then help position them in order that the chemical reaction between these substrates can take place. If they bound things other than the substrates they would be much less efficient in catalyzing the reactions.
The senses of taste and smell are closely related.
There are several factors that affect enzyme itself. 1. Temperature As the shape specificity of the enzyme's active site is vital for any enzyme reaction, therefore an optimal temperature is important for enzymes. Enzymes will be inactive under low temperatures since it has too low kinetic energy to start the reaction or quickens the reaction. Alternatively, enzyme's structure and the shape of active site will changed in high temperature. Eventually, enzymes are denature and never can be used again. 2. pH value As mentioned, the structure of enzyme is highly sensitive to the external environment, therefore pH value of the environment also has an effect on enzymes. Again, the shape of enzymes changed outside the range of pH value that suits particular enzymes. For instance, the optimum pH value for enzymes in stomach is around pH 2 whereas most are pH 7. 3. Presence of inhibitor There are 2 types of inhibitor, one is non-competition inhibitor. These inhibitors will bind to the allosteric site (alternative site) of the enzymes that alters the shape of active site, therefore preventing the substrate from binding the enzymes and having reactions.
I think it is called family. Hope this helps.

The increase of enzyme concentration increase the rate of reaction. Given a fixed amount of substrates, it means that the substrates will be digested faster as there are more enzymes to do the work. Substrate concentration, temperature, and pH value of the surrounding where the enzymes work on also affects the rate.
... substrate? Yes, many enzymes can work on any of a family of related compounds.
What is RNA closely related too? What is RNA closely related too?
Enzymes are catalysts.
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
Eagles are closely related to hawks.
Closely related: obelia jellyfish Not closely related (but still related): coral sea anemone
They catalyze hydrolysis reactions. These are reactions in which water is added to cause larger molecules (like long carbohydrates and other polymers) to break down into smaller subunits. Enzymes are typically named for the type of reaction they catalyze or for the substrate/product related to the enzymatic reaction
The dugong is closely related to the manatee.
Enzymes are highly specific. Each enzyme catalyzes a particular chemical reaction or at most a family of closely related chemical reactions.
No. Kurds are closely related Persians. Azeris are closely related to Turks.
