Enzymes are proteins that are made by living cells. They act as catalysts, speeding up the chemical reaction process, remaining unchanged before and after. They do so by lowering the activation energy, meaning when they are present, less energy is required for the reaction to occur. The enzymes act on a substrate during the process. A substrate is any compound the enzyme bonds with. However, the substrate must match a specific shape for the two to bond properly. This is known as the key and lock

out these actions? Enzymes play a huge part in cellular activity, as was discovered in 1896 (Human Touch of Chemistry). Enzymes were originally found while trying to ferment glucose into alcohol. Scientists couldn't figure out how to carry out this process without living yeast. Eduard Buchner proved that glucose could be turned into alcohol without living yeast by using juice he obtained from yeast, but didn't know what to call the things acting inside that juice. Enzymes translate to "in yeast"

The Effect of Temperature on the Enzymatic Activity of Amylase Enzymes are biological molecules or proteins that act as catalysts and help complex reactions occur everywhere in life. The enzyme and the substrate are in the same area, closely together. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/ substrate complex. After this, the substrate is changed. It can either be broken down or combined with another molecule to make something

An enzyme is a catalysis that speeds up a reaction. Some enzymes are non-specific and some are highly specific. The active site on an enzyme is where the chemical reactions occur. Substrates, which are the reactants, bind to the active site. For specific enzymes, only substrates that fit the three-dimensional shape and structure of the active site can bind with it. When a substrate binds with an active site an enzyme-substrate complex (ES) is made. Only the substrates undergo chemical changes while

Enzymes inhibitors Enzymes are a biological catalyst that accelerates a chemical reaction without itself being affected by the reaction. Enzymes are helpful because they speed up reactions. According to George Shields, “Protein enzymes work by bringing the reactants in a chemical reaction together in the most favorable geometrical arrangement, so that bonds can be easily broken and reformed. This is possible because different enzymes have different three-dimensional shapes.” Another function

How the Ingredients Found In Beer are Beneficial to Our Health Drinking beer for some people who likes to go to the party or just relaxing their body is a habit. However, some people think beer is the alcohol drink that effects bad habit, cause be hangover, and has high risks for some diseases. Besides that, some people consider that consuming beer intake too much can damage the body’s digestive system, kidney, and fetuses of pregnant women. Apparently that drinking beer has positive effects to

Unit 2: Cell Biology SCIE206-1401B-08 Photosynthesis and cellular respiration make one large cycle that sustains life on earth. Through photosynthesis the suns energy is constantly being transformed into glucose, which is a chemical energy. Respiration is the chemical activity that occurs in all plants and animal cells that release the energy from the glucose. Photosynthesis cannot exist with cellular respiration, they are completely linked together in providing the energy through the food

from Breast Cancer to Turner Syndrome. The genetic disorder I'm doing is Galactosemia, Galactosemia is an inherited metabolic disorder in which galactose builds up in the blood because of deficiency of an enzyme catalyzing its conversion to glucose. Galactosemia is caused by the lack of a liver enzyme that is needed to metabolize Galactose. It's transmitted by the presence of 2 recessive mutant genes on a autosome. It's also a very rare disease. Galactosemia usually occurs in infants. Some of the symptoms
