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.
Enzymes a special type of protein.
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.
Energy In Reactions Energy is released or absorbed whenever chemical bonds are formed or broken. Because chemical reactions involve breaking and forming.
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.
Identify and Investigate the role of enzymes.
Enzymes Mrs. Harlin Explain how enzymes act as catalysts for biological reactions.
Catalysts speed up the rate of the reaction.
Grade 10 - Enzymes Enzyme Action.
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.
C astlehead H igh S chool Enzymes We couldn’t live with out them! Intermediate 2.
Control METABOLISM Metabolic reactions can be controlled and sped up by enzymes that lower the activation energy needed. –metabolic reactions would.
What happens to the food that we eat?. IT BREAKS DOWN INTO…. Carbohydrates Proteins Fats NUCLEIC ACIDS!
Homeostasis of Enzymes What is an enzyme? How do enzymes work? What factors can effect enzyme action?
