What is the cite when other substrates bind to enzymes to alter activity?

The competitive inhibitors bind in the active site while noncompetitive inhibitors bind at an allosteric site, which is located somewhere else on the enzyme other than the active site.

What is enzyme affinity?
its how enzymes and substrates are attracted to each other
Can an enzyme continue to ract with other molecules once it has finished reacting with one?
Yes, proteic enzymes are not denatured by reacting with their substrates.
What other means does a cell use to control enzymatic activity?
compartmentalization of enzymes into defined organelles
What happens to the rate of enzyme reaction when you increase the enzyme concentration?
As the enzyme concentration increases, the rate of reaction will increase because there are many more enzymes present to aid break down the substrate. However, a point will be reached when no matter how much enzyme is present, the reaction will not occur any quicker. This is equilibrium. This happens because all the substrate is being broken down by the exact same amount of enzyme, so enzymes will be present which have no substrate to break down.
What three things can affect the way enzymes work and explain how each factor affects an enzyme activity?
Enzymes act as biological catalysts which means they speed up chemical reactions in living things. 3 things that affect its rate would be temperature, pH, and regulatory proteins that turn them on or off.

What do enzymes and substrates look like?
Enzymes and substrates are molecules and look like any other molecules. In case of enzymes specifically, they are proteins and so have long chains of amino acids folded into different structures and shapes.
Can an enzyme continue to ract with other molecules once it has finished reacting with one?
Yes, proteic enzymes are not denatured by reacting with their substrates.
What happens to enzymes at a low pH?
The activity of the enzymes depends on the specific pH needed.
What other means does a cell use to control enzymatic activity?
compartmentalization of enzymes into defined organelles
Is the non protein part of an enzyme will attach with enzyme after making product?
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions.[1][2] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.Like all catalysts, enzymes work by lowering the activation energy (Ea‡) for a reaction, thus dramatically increasing the rate of the reaction. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts by being much more specific. Enzymes are known to catalyze about 4,000 biochemical reactions.[3] A few RNA molecules called ribozymes also catalyze reactions, with an important example being some parts of the ribosome.[4][5] Synthetic molecules called artificial enzymes also display enzyme-like catalysis.[6]Enzyme activity can be affected by other molecules. Inhibitors are molecules that decrease enzyme activity; activators are molecules that increase activity. Many drugs and poisons are enzyme inhibitors. Activity is also affected by temperature, chemical environment (e.g., pH), and the concentration of substrate. Some enzymes are used commercially, for example, in the synthesis of antibiotics. In addition, some household products use enzymes to speed up biochemical reactions (e.g., enzymes in biological washing powders break down protein or fat stains on clothes; enzymes in meat tenderizers break down proteins, making the meat easier to chew).
How does enzyme concentration affects the rate of enzyme action?
it slows down the reaction time of the enzyme because there are too many substrates bumping into each other and make it harder for them to bind to the enzymes.
What other main functions do proteins serve?
as enzymes to control the rate of reactions and regulate cellular activity

Is hockey an indirectly competitive activity?
No, it is a directly competitive activity: you play against the opponent and what you both do can alter the game for the other, not to mention you will often directly compete for the ball with them.
What does a enzyme-substrate complex do?
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
