They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a “catalyst.”. Enzymes are biological catalysts--they catalyze the chemical reactions that happen inside living things.
Oct 26, 2019 · Organic Compounds : Carbon atoms bonded together make up most of the chemical compounds in living things. Monosaccharides : Single sugar molecules such as Glucose. Disaccharides : 2 sugar molecules bonded together such as Sucrose,Lacotse and Maltose. Polysaccharides : Made up of many sugar molecules bonded together.
On a basic level, enzymes promote chemical reactions that involve more than one substrate by bringing the substrates together in an optimal orientation. The appropriate region (atoms and bonds) of one molecule is juxtaposed to the appropriate region of the other molecule with which it must react.
Enzymes are essential for life because they speed up thousands of biochemical reactions that occur in living cells. In this webpage, you will learn what enzymes are, how they work, and how they are regulated. You will also explore some examples of enzymes and their roles in different biological processes. If you want to understand the basics of enzymes and their functions, click here to read more.
The Bio-Dictionary helps you to understand common terms in biology. Definitions come in the form of a figure with accompanying text, a short video , or both. The Explorer's Guide to Biology (XBio) is a free resource for students in higher education and self-learners.
Oct 27, 2020 · Definition. Amino acids are the building blocks of polypeptides and proteins and play important roles in metabolic pathway, gene expression, and cell signal transduction regulation. A single organic amino acid molecule contains two functional groups – amine and carboxyl – and a unique side chain.
In supplementary gene action, the dominant allele of one gene is essential for the development of the concerned phenotype, while the other gene modifies the expression of the first gene. For example, the development of grain colour in maize is governed by 2 dominant genes ‘R’ and ‘P’.
