Enzymes

Enzymes

Biological catalysts in living organisms

Catalase

Enzyme in yeast the breaks downs H2O2

Substrate

Reactants that the enzyme act on

Active Site (Shape matching that substrate)

Interacts with substrate

Product

Outcome of reaction

Denatured Enzyme

Enzyme loses its shape and is unable to function

Sucrase

Breaks down sucrose

Protease

Break downs proteins

Lipases

Breaks down lipids

Activation Energy

Energy needed to kickstart a chemical reaction

Exothermic Reactions

does not need additional energy from outside sources

Endothermic 

Constantly taking energy from surrounding 

Enzyme Temperature (High)

Denatures it by breaking H bonds

Enzyme Temperature (Low)

Functions slowly

Enzyme Temperature (Ideal) 

37C

Enzyme pH

Extreme pH damages the active site

Inhibitors

Slow down enzyme

Competitive Inhibitors

compete with other substrates to bind to the active site

Noncompetitive Inhibitors

Changes the shape of the enzyme so it cannot bind to the substrate
