One, and that is the Beauty of Life. In a laboratory a chemist is super-happy to obtain a 60% yield in a reaction - means 40% waste-product. Any Cell, with its thousands of chemical reactions occurring constantly and simultaneously, would IMMEDIATELY BOG-DOWN in useless by-products unless the YIELD of each and every ENZYME was not 100%.

∙ 14y agoThe function of enzymes depends on their shape. Each enzyme can perform as many reactions as they can, and as many times as they can. Each enzyme goes through a process that allows them to perform a reaction by connecting with at least two substrates.

∙ 10y agoAn enzyme is a protein that speeds up a chemical interaction without itself being consumed in the reaction. There are thousands of known enzymes in the human body, and each catalyzes a variable number of reactions.

What are two other processes catalyzed by enzymes?
Enzymes act as a catalyst in biochemical reactions. Hence they are the key players of all the reactions that occurs in cells, such as metabolic conversions, synthesis and degradation of biomolecules and so on.
Why do humans have so many emzines?
We have LOTS of enzymes to speed up all the different reactions that happen in the human body Each sort of enzyme can only speed up one specific reaction (eg. lipase can only break down fats). This is because their active site will only fit a specific sort of molecule. However, the body needs to carry out lots of processes: it needs to digest fats, proteins and carbohydrates, it needs to build new molecules... And it needs an enzyme which is specific to those reactions.
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
Why does Enzyme reaction rate decrease at 37 degrees?
Enzymes are catalysts for chemical reactions. All chemical reactions are affected by temperature. Higher temperatures make the reactions happen faster, and colder temperatures make them happen slower. At 37 degrees, just a little above freezing, many biological enzymes practically stop working.
How many substrates can an enzyme have?
A given enzyme works on ONE TYPE of substrate
Why only a small amount of enzyme is needed to catalyse a reaction involving many molecoles?
The principle reason a little bit of enzyme can catalyze a reaction involving many molecules is that enzymes are not consumed by the reactions they catalyze. Enzymes are typically multi-use entities and will continue acting until all substrates are reacted.
Why is it necessary for a cell to produce one enzyme molecule for every substrate molecule that needs to be catalyzed?
Because evey substrate needs its own enzyme. Every substance has it depends upon the dissociation constant for the enzyme/substrate interaction. Some enzymes can catalyze reactions for low-affinity substrates, as long as the concentration of substrate molecules is great enough.
How many different chemical reactions can a single enzyme catalyze?

The purpose of the many chemical reactions in your body?
using oxygen to oxidize breaking down metabolic compounds via heat, for absorbortion of nutrients, warmth, to catalyse other chemical reactions for electrochemical functions of nerves and cells...
How many different kinds of chemical reactions can one kind of enzyme control?

Why does the body need so many different enzymes?
A large number of reactions occur in the cell, many of which requiring enzymes to work. From the creation of the ATP used to energize the cell to the creation of proteins from RNA, each new type of reaction needs its own enzyme to work, and often need dozens if not hundreds of that enzyme to do the reaction at the pace it needs.
How many times a enzyme is renewable?
Infinitely. Enzymes are biological catalysts and a catalyst is never used up in chemical reactions.
How temperature affects the enzyme catalysed biochemical reactions?

What is importance of enzyme?
They carry out chemical reactions to the cells and breaks down things to be digested. They also allow many chemical reactions to occur within the homeostasis constraints of a living system.
What does small amount of an enzyme can cause the reaction of large quantities of substrate mean?
That enzymes can catalyze reactions and remain unchanged by those reactions, causing many reactions per second. Enzymes are protein machines that are reusable and rapid catalyzers.
What is the difference a reaction without an enzyme and a reaction with an enzyme?
The speed at which the reaction takes place. Many reactions, especially exergonic reactions, would take place naturally, but too slowly to help living cells carry out the work they need to do. So enzymes lower the activation energy needed to start the reaction and these reactions in the cell are speed-ed up enough for cellular work to be done.
