Enzymes Enzymes are the crucial ingredient to any living organisms, which are known to speed up chemical reactions. Enzymes are proteins which function in catalyzing a chemical reaction by lowering the activation energy. While enzymes are known to be biological catalyst by being able to speed up reactions in photosynthesis, respiration, and the production of new proteins. A catalyst is a molecule that speeds up a chemical reaction by lowering the activation energy required to start the reaction. Energy is required for a biochemical reaction to proceed. The energy required to start this reaction is much lower in the presence of an enzyme than without an enzyme. Enzymes are biological catalysts that carry out thousands of chemical reactions, which occur in living cells. …show more content…
ATP is known to be adenosine triphosphate, which is also called a nucleoside triphosphate. ATP is an energy carrier due to being referred to being known as the “universal currency” of intracellular energy transfer. ATP is an energy carrier. ATP contains two broken bonds that attach the three phosphate groups to the rest of the molecule, which can easily be broken by hydrolysis. While ATP is a short term energy also made during photosynthesis. As proteins, upon their synthesis, enzymes assume particular shapes. This shape, especially in its “active site”, determines its catalytic effects. The active site of each enzyme binds to specific molecules. The active site bonds with a substrate, a binding site, and catalyzes a reaction to that specific substrate. When an enzyme binds to an active site it can change the shape in order for it to catalysis. At the moment the enzyme binds to its substrate it then forms an enzyme-substrate
