The flexibility of the [National Qualifications] framework means that candidates may take a mixture of Higher courses and National 5 courses in S5, with a view to studying the Higher equivalent in S6, thus gaining university qualifications across two years. This system maximises the opportunities available to candidates of differing abilities.
Until 2014, the Standard Grade section of the site had 12 subjects: Biology, History, Chemistry, Computing Studies, Maths, English, Modern Studies (a course exclusive to Scotland), French, Physical Education, Geography, and Physics. [9] The site was updated in 2014 to replace the Standard Grade section with National 4 and National 5 sections.
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 BBC Learning Zone (previously The Learning Zone) was an educational strand run by the BBC as an overnight service on BBC Two. It broadcast programming aimed at students in Primary, Secondary and Higher Education as well as to adult learners.
5′-Nucleotidase (EC 3.1.3.5) is an enzyme which catalyzes the phosphorylytic cleavage of 5′-nucleotides. [2] Although originally found in snake venom, [ 3 ] the activity of 5'nucleotidase has been described for bacteria and plant cells, and is widely distributed in vertebrate tissue. [ 4 ]

Trypsin is an enzyme in the first section of the small intestine that starts the digestion of protein molecules by cutting long chains of amino acids into smaller pieces. It is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins.
The rate acceleration conferred by enzymatic catalysis is often enormous—as much as 10 17-fold increase in rate over the uncatalysed reaction in the case of orotate decarboxylase (78 million years without the enzyme, 18 milliseconds with the enzyme). [59] The molecules bound and acted upon by enzymes are called substrates.
