Enzymes can be involved at every step in a reaction pathway. At each step, the molecule is transformed into another form, due to the presence of a specific enzyme. Such a reaciton pathway can ...

Reaction pathway diagrams display information about the energy changes during chemical reactions. Chemical energy Energy changes occur in chemical reactions as bonds are broken and new bonds formed.

The energy changes that take place during a reaction can be shown on a reaction profile diagram. During a chemical reaction, heat energy can be given out or taken in by the chemicals. This can cause ...
