Who else can act as a catalyst for the cell?

The daily operations of cells are carried out through biochemical reactions that take place inside the cell. Reactions turn on and off, or speed up and slow down, according to the immediate needs of the cell and its functions. At any given time, it is necessary to control and balance the numerous pathways associated with the build-up and destruction of cellular components. To achieve this, cells organize reactions in various pathways based on enzymes.

Enzymes are protein catalysts that accelerate biochemical reactions by promoting molecular rearrangements that support cell function.
