Presentation Transcript

  1. Enzymes Regulate cell chemisty

  2. Enzymes • Enzymes- are biological catalysts, or chemicals that accelerate a chemical reaction without itself being affected by the reaction.

  3. Enzymes • Groups of enzymes work together to carry out a given metabolic function. • This process must be regulated in order to allow the cell to meet its changing needs for energy.

  4. Enzymes • Enzymes - are vital to such bodily functions as digestion

  5. Enzymes • 1.Enzyme – usually end in ase • Amylase -enzyme that catalyses the breakdown of starch into sugars (saliva) • Lactase – enzyme that breaks down sugar to produce energy

  6. Enzymes often associate with other molecules to get the job done….. • Enzymes often associate with other molecules to get the job done

  7. Enzymes • Cofactor Aid in the action of the enzyme • Non-protein • link to enzymes / presence is essential to the activity of those enzymes

  8. Enzymes • Cofactors work by changing the shape of an enzyme • Specificity

  9. Enzymes • 3. Substrate In an enzymatic reaction, the reactant that the enzyme acts upon is: • Substrate Lactase Lactose Galactose Glucose

  10. Enzymes • A number of variables effect enzyme activity: • Temperature • pH

  11. EnzymesHeat-sensitive enzyme Controls Melanin • Less enzyme activity in warmer areas (lighter) • More enzyme activity in cooler areas(darker) • The enzyme the determines melanin optimal temp is below 103
