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).
Activation energy is the energy that must be provided to make a reaction take place. The enzyme helps speed up the reaction by lowering the activation energy making the reaction occur at a lower temperature than it would without an enzyme.So when a substrate binds to the active site of an enzyme, the shape of its molecule is lsighty changed. this makes it easier to change into a product. AS student.It lowers it.
a cell's protein
a repressor is a protein that binds to DNA, which turns off the genes that code for the digestive enzymes. the promoter, located near the digestive enzyme genes, is a section on DNA that serves as the binding site for the enzyme RNA polymers.
The role of arestriction enzyme is to remove the intronsto make a mature mRNA, so that the new mRNA codes for the making of a single protein. The restriction enzyme will only leave the exons to make the mRNA more shorter, and therefore easier to insert into plasmids
gangnam style
the RNA is the component of the ribosome, and is the enzyme that is the site of protein synthesis (the making of protein) in all living cells.
Whey protein isolate is produced through a series of filtration processes that remove most of the fats and lactose from whey. Here are the steps involved: 1)Milk Collection: Whey is a liquid that separates from milk during the cheese-making process. This liquid is collected and pasteurized to kill any harmful bacteria. 2)Filtration: The whey undergoes a filtration process to remove the larger protein molecules and other impurities. 3)Ion Exchange or Microfiltration: This step further separates the whey protein from fats and carbohydrates. Ion exchange uses charged resins to selectively remove the protein, while microfiltration uses membranes with tiny pores to filter out the protein. 4)Drying: After filtration, the remaining whey protein solution is dried to create a powder form. 5)Additional Processing: Some manufacturers may also use processes like hydrolysis to break down the protein into smaller peptides for easier digestion. Whey protein isolate is known for its high protein content (usually 90% or more), low lactose, and low fat, making it a popular choice for athletes and fitness enthusiasts looking to supplement their protein intake. I personally use whey protein isolate from Boditronics, and I highly recommend it. It's a high-quality product that provides a great source of protein without unnecessary additives or fillers. You can check out their products and learn more about whey protein isolate at Boditronics. Website:-boditronics.co.uk/
Enzymes are metabolism controlling agent. Enzymes act as a catalyst to increase the efficiency of chemical reactions without being use up of themselves.Enzymes are made up of Proteins.Without participation of enzymes reaction will proceed slowly and making life impossible.
Yes and most biochemical path ways are regulated by negative feedback. Enough of the product made inhibits the enzyme, or biochemical pathway, from making more product/reactions.
Pectin is actually a naturally occurring complex carbohydrate, not a protein. It is found in many fruits, particularly apples. It is used in jam and jelly making to help firm the final product.
yeast
No, pectin is not an animal product, it is an enzyme found in fruits and it is used to help boiled sugar set when making jam.
Pineapples contain an enzyme called bromelain. THis enzyme stops the Jello from jelling because it breaks dowm the strands of protein that form Jello. Cooking the pineapple denatures this enzyme therefore preventing it from stopping the Jello.
No, nucleic acids code for the making of protein, they do not contain the monomers of protein manufacturing.

They are just as effective as making your own protein shake at home.
Meat tenderizer is made up of protease enzymes, usually papain and bromelain, that attack the protein structure of meat and makes less tough or more tender. An enzyme is biocatalyst that is itself made of a highly structured protein or proteins thus making it a biochemical and organic material. A catalyst, on the other hand, will still speed up chemical reactions like an enzyme, but cannot be classified as a biochemical or organic material; a catalyst is an inorganic or non-biochemical material that will speed chemical reactions.
