<u>Keys(enzymes) are specific to certain locks(substrate)</u>
Explanation:
<u>The key and lock model are used to illustrate the enzyme specificity to a substrate</u> function. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reactions.
For enzymes to catalyze a reaction, the substrate(s) must fit in the active site on the surface of the enzyme. This forms an enzyme-substrate complex. The enzymes speed up the formation of the products. The products formed separate from the enzymes so that other substrate molecules can fit into the active sites.
The products of cellular respiration are carbon dioxide, ATP, and water. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
