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 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.
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 CSE was graded on a numerical scale from 1 to 5, with 1 being the highest and 5 the lowest passing grade. Below 5 there was a U (ungraded) grade. The highest grade, 1, was considered equivalent to an O-Level C grade or above, and achievement of this grade often indicated that the pupil could have taken an O-Level course in the subject to ...
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
The 5' cap is added to the 5' end of the pre-mRNA molecule and is composed of a guanine nucleotide modified through methylation. The purpose of the 5' cap is to prevent break down of mature mRNA molecules before translation, the cap also aids binding of the ribosome to the mRNA to start translation [ 8 ] and enables mRNA to be differentiated ...
Serine proteases are a very common and diverse family of enzymes, including digestive enzymes (trypsin, chymotrypsin, and elastase), several enzymes of the blood clotting cascade and many others. In these serine proteases, the E* intermediate is an acyl-enzyme species formed by the attack of an active site serine residue on a peptide bond in a ...
