Biochemistry Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Over the last decades of the 20th century, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine to genetics are

Biological Pathways A biological pathway is a series of actions among molecules in a cell that leads to a certain product or a change in the cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein. Pathways can also turn genes on and off, or spur a cell to move. Top of page.

Enzyme Biochemistry - What Enzymes Are and How They Work Definition of an Enzyme An enzyme is defined as a macromolecule that catalyzes a biochemical reaction. In this type of chemical reaction, the starting molecules are called substrates. The enzyme interacts with a substrate, converting it into a new product. Most enzymes are named by combining the name of the substrate with the -ase suffix (e.g., protease, urease).

reaction A reaction is an action taken in response to something. If you're telling your parents that you want to move out, you'll see by their reaction that they're sad about it. A reaction is often a physical in nature. A chemical reaction describes the way a chemical behaves when combined with another substance. The way your body responds to a medication or external influence is a physical reaction. Think of the way cold air causes you to get goose bumps on your arms.

Structural Biochemistry/Metabolism 3.Biochemical regulation Metabolic reactions can also be controlled by reactions at the biochemical level. In this case, the binding of a molecule to an enzyme directly regulates its function. Biochemical regulation is typically categorized according to the site where the regulatory molecule binds.

Principles of Biomedical Science End of Course Review PBS Activity Introductions Enzymes are biological molecules that catalyse (speed up) chemical reactions. Enzymes are specific—they will only work on particular molecules. For example, the enzyme sucrase will only bind with and break bonds in sucrose, not any other type of sugar.nother characteristic of enzymes is that they can be re-used over and over again. A single enzyme will typically catalyse around 10,000 chemical reactions per second. This means that only a tiny amount of enzyme is needed to have a huge effect on a reaction.

HELP on 2 biology questions. 10 points? 1. Chemical reactions where molecules are joined together to form more complex structures are known as anabolic chemical reactions. You can remember this term because some people use anabolic steroids to build muscle. An example of an anabolic reaction is the synthesis of glycogen from individual glucose molecules.

Chemical Reactions A chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms.Chemical reactions are represented by balanced chemical equations, with chemical formulas symbolizing reactants and products. For specific chemical reactants, two questions may be posed about a possible chemical reaction.ombination Reactions. In combination reactions, two substances, either elements or compounds, react to produce a single compound. One type of combination reaction involves two elements. Most metals react with most nonmetals to form ionic compounds.

Chemical Reaction Definition and Examples By Anne Marie Helmenstine, Ph.D. Definition: A chemical reaction is a chemical change which forms new substances. Also Known As: reaction, chemical change. Examples: The chemical reaction H 2 (g) + ½ O 2 (g) → H 2 O(l) describes the formation of water from its elements.

reaction A rearrangement of the atoms or molecules of two or more substances that come into contact with each other, resulting in the formation of one or more new substances. Chemical reactions are caused by electrons of one substance interacting with those of another. The reaction of an acid with a base, for example, results in the creation of a salt and water. Some, but not all, reactions can be reversed.
