Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

FUNCTIONS OF ENZYMES Enzymes are extremely important to the human body and its ability to function. An enzyme itself is a protein made by the body’s cells to act as catalyst‚ speeding up chemical reactions in the cell. It does this by taking the reactants‚ or the elements or compounds that enter into the chemical reaction‚ in this situation referred to as substrates‚ and breaking apart their bonds so that new ones can form. The three types of enzymes are digestive enzymes‚ food enzymes‚ and metabolic

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic

Gustavo Carro BIO-105 Human vertebral column In human anatomy‚ the vertebral column is a column usually consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx. It is situated in the dorsal aspect of the torso‚ separated by intervertebral discs. It houses and protects the spinal cord in its spinal canal. There are normally thirty-three (33) vertebrae in humans‚ including the five that are fused to form the sacrum (the others are separated by intervertebral

The regulation of enzyme activities mostly involves the inhibition of substrates‚ and this inhibition is divided into two types. The first type‚ competitive inhibitor‚ binds the inhibitors at the active site
