The number of protons,neutrons,electrons, the way the are classified (earth metal, noble gas,meteoroids) and also the way they react.
The given image is showing the interaction of the enzyme and its substrate.
In the first part of the image, the enzyme and substrate are not bind together. They are present in close proximity. The enzyme shown in the picture have a site for the attachment of the substrates.
In the next picture, the interaction of the enzyme and the substrate has occurred, which resulted in the formation of the enzyme substrate complex. Hence, the given picture shows the interaction of an enzyme with the substrates.
