Enzymes Chapter 6.3 page165
Enzyme Lab Catalase Blood & Liver H2O2 Toxic H2O2 +catalase= H2O + O2
Properties of Enzymes Proteins Catalysts Speed reactions Work fastDenature at high temp
Enzyme-Substrate complexActive site = where the substrate ( reaction molecule) connects to enzyme Active Site Substrate Enzyme
Enzymes remain unchanged!Before Enzymes are not used up No more substrate = end to the reaction Synthesis or Decomposition reactions After
Lock & Key Model One enzyme for every substrate unique fit Enzyme
Enzymes are pH specificDifferent enzymes Different body areas Different optimum pH Examples: Stomach= acid pH Mouth= basic pH Blood Mouth Stomach
Enzymes are temperature dependent…...Most at body temperature 37oC Denature at high temperatures
Enzymes: “Helper” Protein molecules
Biology I Enzymes: “Helper” Protein molecules Biology I Flow of energy through life Life is built on chemical reactions.
An enzyme is a biological catalyst that speeds up the rate of reactions in biological processes All enzymes are proteins, coded for by genes Enzymes are.
Enzymes: “Helper” Protein molecules Regents Biology Flow of energy through life Life is built on chemical reactions.
Cells & Enzymes Enzymes Made of protein Present in all living cells Converts substrates into products Biological catalysts Increase the rate of chemical.
Enzymes Enzymes Enzymes: are proteins made of amino acids.Enzymes: are proteins made of amino acids. -Catalyst: they speed up chemical reactions & lower.
Enzymes Mrs. Harlin Explain how enzymes act as catalysts for biological reactions.
Catalysts speed up the rate of the reaction.
Understanding Enzymes Academic Biology. Enzyme A large protein molecule Specific shape with deep folds on its surface Deep folds form pockets called active.
What are the factors affecting Enzyme Activity?. Recap.
Control METABOLISM Metabolic reactions can be controlled and sped up by enzymes that lower the activation energy needed. –metabolic reactions would.
Regents Biology Enzymes – Chapter 2.4 Regents Biology A. Flow of energy Life is built on chemical reactions.
Regents Biology Enzymes: “Helper” Protein molecules.
Cells & Enzymes Converts substrates Present in into products
Control METABOLISM Metabolic reactions can be controlled and sped up by enzymes metabolic reactions would be too slow to occur if no enzymes were.
Enzymes Enzymes are proteins Enzymes are biological catalysts
FACTORS AFFECTING ENZYME ACTIVITY. There is an optimum temperature at which enzymes function best – generally around 40 degrees But why the gradual.
ENZYMES. There are thousands of reactions that occur within organisms. These reactions would occur very slowly or not at all without enzymes.
