Classification of Enzymes - Enzymes are generally classified on the basis of the type of reactions that they catalyse. 6 groups of enzymes can be recognised on this basis. The following table lists the 6 groups of enzymes along with example. fig. 14.15 - Clas..

These are used to break DNA molecule into fragments. They are further of three kinds, Exonucleases, which release nucleotides from 5 or 3 ends of a DNA molecule; Endonucleases, which cleave DNA helix at any point except the at the terminal ends and Restriction endonucleases, which cleave D..

Enzymes and Inorganic Catalysts - Enzymes resemble inorganic catalysts in several aspects and differ from them in many other features. These similarities and differences are summarised in the following table. fig. 14.12 - Similarities and Differences between Enzymes an..

pH plays a very significant role in biochemical reactions. For example, the blood in our bodies is buffered at a pH value of 7.36-7.42 due to bicarbonate - carbonic acid buffer. A mere change of 0.2 pH units can cause death. Certain enzymes get activated only at certa..

These organelles are found in the liver and kidney cells. They are small, membrane-bound sacs, and contain powerful oxidative enzymes. Their chief function is to remove toxic substance..

Liver is the largest gland and is found in the upper part of the abdomen on the right side of the body just below the diaphragm. Its secretion is called bile juice. It is alkaline and rich in organic salts called the bile salts. The alkaline nature serves to neutralize the acidic pH..

It is present at the bend of the duodenum. It secretes pancreatic juice which has an almost neutral pH (6 to 7). This juice is secreted into the common bile duct and then into the duodenum. About 700cc of pancreatic juice is secreted everyday. Pancreatic juice consists of enzymes..

Pancreas are present at the end of the duodenum. It secretes pancreatic juice which has an almost neutral pH (6 to 7). Pancreatic juice consists of enzymes like the pancreatic amylase (to act on carbohydrates), trypsin (to act on proteins) and lipase (to act on lipids and fats)..

It is the step in which each of the participating amino acid reacts with ATP to form amino acid AMP complex and pyrophosphate. The reaction is catalyzed by a specific amino acid activating enzyme called aminoacyl-tRNA synthetase in the presence of Mg2+. There is a separate aminoacyl tRNA..

The radiant energy from the sun is the source of both light and heat energy to photosynthesis. Light energy is harvested by the pigments in order to carry out the breaking down of water molecule into hydrogen and oxygen. This is an energy-intensive process. Sunlight can be split into seven differen..
