Enzymes the biochemical catalysts Control chemical reactions in living cells.

Enzymes – the biochemical catalysts • Control chemical reactions in living cells

Activation Energy

• For a reaction to occur the reactant particles must collide.

• If the collisions have sufficient energy then a reaction takes place (old bonds break and new bonds form)

• The greater the activation energy the slower the rate of reaction at a given temperature.

Activation energy decreases with the addition of a enzyme!

Enzymes – the biochemical catalysts

• Biochemical reactions are vital to life. Without enzymes these biochemical reactions in our cells and other organism’s cells would occur to slowly to sustain life!

• Vital to all life on earth!
