An investigation into the effect of substrate concentration on the activity of the enzyme catalase in potato tissue.

Enzymes are globular protein molecules known commonly as biologic Catalysts. The definition of a catalyst is a substance that jailor be used to speed up the rate of a chemical reaction while remaining unaffected and unchanged after the reaction. The enzymes ability to act relies strongly upon the specific cook of the protein molecule, which is coiled into a precise three-dimensional lick. This specific cook is the cleft or depression, which other molecules (substratums) fit into perfectly; this divide of the enzyme, is called the alive(p) site. The tertiary folding of the polypeptides causes the intricate specific shape of the expeditious site. The substratums are held in the supple site by forming temporary sniper bonds with the hydrophilic R groups of the enzymes amino acids. Here we have a diagram showing the lock and key theory of enzyme action. sumeetbanker, please do non redistribute this stimulate.

Anybody found doing so resolving be permanently banned. The substrate (key) is shown fitting perfectly into the active site (lock). The substrate binds to the enzyme and forms an enzyme-substrate complex.

The reaction then takes place immediately and a substrate is either broken down into two or more than products (catabolic reaction) or two or more substrates are bonded to nettle one product (anabolic reaction). The induced fit theory states that ab initio the active site is no the perfect s hape of the substrate but as it approaches, ! the shape of the active site changes to hit the perfect fit. sumeetbanker, please do not redistribute this project.
