Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [1] Carbohydrases are produced in the pancreas, salivary glands and small intestine, breaking down polysaccharides.
The site was updated in 2014 to replace the Standard Grade section with National 4 and National 5 sections. Gaelic versions of these were also made available. Until 2014, in the Higher section, Biology, English, Geography, Maths, Chemistry, History, Modern Studies, Physics and the Scotland-only subject Scottish Gaelic were available. The Higher ...
Organisation of enzyme structure and lysozyme example. Binding sites in blue, catalytic site in red and peptidoglycan substrate in black. (In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
This regulation is to ensure that the body is not over-producing pyruvate molecules. The regulation also allows for the storage of glucose molecules into fatty acids. [5] There are various enzymes that are used throughout glycolysis. The enzymes upregulate, downregulate, and feedback regulate the process.
The citric acid cycle is an 8-step process involving 18 different enzymes and co-enzymes. During the cycle, acetyl-CoA (2 carbons) + oxaloacetate (4 carbons) yields citrate (6 carbons), which is rearranged to a more reactive form called isocitrate (6 carbons).
Ribbon diagram of a protease (TEV protease) complexed with its peptide substrate in black with catalytic residues in red.(. A protease (also called a peptidase, proteinase, or proteolytic enzyme) [1] is an enzyme that catalyzes proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products. [2]
In 1888, the Scottish Leaving Certificate was established in response to the terms of the Education Act of 1872. It was designed to have higher and lower levels assessed as individual subjects including Mathematics, Ancient or Modern Foreign Language, Science, etc.
Enzyme denaturation is normally linked to temperatures above a species' normal level; as a result, enzymes from bacteria living in volcanic environments such as hot springs are prized by industrial users for their ability to function at high temperatures, allowing enzyme-catalysed reactions to be operated at a very high rate.
