Metabolism Reactions in your bodyBody would burn up to get the amount of energy needed ( for molecules to collide with enough energy for reaction to occur)
What are Enzymes? Protein catalyst Act on substrates (reactants)End in ASE Ex. Lactase digest lactose HOW?
Lower “Activation Energy”
Enzymes Without Enzyme With Enzyme Free EnergyProgress of the reaction Reactants Products Free energy of activation
Enzyme Substrate Complex
Enzyme Substrate Complex
Enzymes are Specific! Active Site Induced Fit
Enzymes can be REUSED Product is release
A product can be used as a substrate for another enzymeE1 E2 E3 E4 E5 E6 A B C D E F G NOT ON TEST!
Factors Effecting Enzymatic SpeedTemperature pH Substrate concentration Enzyme Concentration WILL DISCUSS these 2 WHEN WE GET BACK (IN OUR LAB)
Temperature Enzymes are PROTEIN Heat too high they can denature
pH Enzymes work best at an ‘optimal’ pH Proteins can denature
Substrate ConcentrationThe more substrate the more reaction Once all of the enzymes are being used the reaction cannot increase Lab when we get back – skip
Enzyme Concentration Control by phosphorylationActivate Add Phosphate (energy from ATP) Lab when we get back- skip
Enzyme Inhibition Competitive Noncompetitive SKIPEI- Substrate can’t get to active site Comepitive- inhibitor binds to active site Noncompetitive-inhibitor binds to ALLOSTERIC SITE
Feedback Inhibition Activity of enzyme can be regulated by its end product SKIP!!!
Enzyme Cofactors Help enzymes function Inorganic Organic- CoenzymesCopper, Zinc, Iron Organic- Coenzymes Vitamins
Pellagra Lack vitamin B3 pyrrolase
Scurvy Enzymes that impairs wound healingLack vitamin C- ships- throw over board- pick them up
Chemical Reactions and Enzymes
Factors Affecting Enzyme Activity

Enzymes. What are Enzymes? proteins Most enzymes are proteins catalyst Act as catalyst to accelerate a reaction Not permanently Not permanently changed.
Enzymes Functions and Control. Enzyme Terms Substrate - the material and enzyme works on. Enzyme names: Ex. Sucrase - ase name of an enzyme - ase.
Slide 1 of 50 Enzymes Enzymes are biological catalysts Proteins Catalyst Lower activation energy Increases the rate of the reaction Affects.
Chapter 6 Enzymes. Metabolic Reactions Metabolism – All the reactions that happen in the cell – Reactions have two sides 1.What goes into the reaction.
ENZYMES ARE PROTEINS THAT SPEED UP SPECIFIC REACTIONS IN CELLS

1 Enzymes section A chemical reaction is the process of making or breaking the chemical bonds that link atoms. 2. When the bonds are broken, energy.
6-1 Unit E: Enzymes. 6-2 An enzyme is a protein molecule that functions as an organic catalyst to speed a chemical reaction. An enzyme brings together.

1. Proteins Enzymes are specialized Proteins Catalysts Act as Catalysts to accelerate a reaction Not permanently Not permanently changed in the.
Enzymes 1. What Are Enzymes? ( Most enzymes are Proteins (tertiary and quaternary structures) Act as Catalyst to accelerates a reaction Not used as part.
ENZYMES. Enzymes are Catalysts Catalytic proteins: change the rate of reactions w/o being consumed Enzymes speed up reactions by lowering the activation.
5.2 Enzymes and Metabolic Pathways Many chemical reactions in the cell are linked in metabolic pathways. The product of one reaction is the reactant for.
Enzymes Textbook Pages Enzymes are important Digestion, Immune function, cell division, etc. Basically everything produced or changed in our bodies.
Enzymes Explain enzyme action and factors influencing their action Temperature pH Substrate concentration Feedback inhibition Competitive inhibition.
Enzymes Enzymes speed up the cell’s chemical reactions The cell uses catalysis to drive (speed up) biological reactions –Catalysis is accomplished by enzymes,
