1 Energy and Enzymes identify reactions as endergonic or exergonic.

2 Things in a class room Things you find at the snack bar Things a Referee does Something Mr. Gordon would wear Things you find in the Gym Things Mr. Lottes would say

3 Catabolic vs. Anabolic Talk to your neighbor. What is the difference. Which uses energy, which makes energy? identify reactions as endergonic or exergonic

4 Identify anabolic and catabolic identify reactions as endergonic or exergonic

5 Energy forms Identify the picture as either kinetic or potential energy identify reactions as endergonic or exergonic

6 Identify the picture as either kinetic or potential energy identify reactions as endergonic or exergonic

7 Identify the picture as either kinetic or potential energy identify reactions as endergonic or exergonic

8 Identify the picture as either kinetic or potential energy Heat, or thermal energy identify reactions as endergonic or exergonic

9 What do they have in common identify reactions as endergonic or exergonic Chemical Energy

10 Free Energy G Portion of energy able to do work What does a - G Exergonic Endergonic identify reactions as endergonic or exergonic

11 Identify endergonic and exergonic identify reactions as endergonic or exergonic

12 Energy Coupling What are three types of work that cells can do? Chemical work Transport work Mechanical work describe the key role of ATP in energy coupling

13 Energy Coupling Vocab words: Phosphorolation ATP ADP describe the key role of ATP in energy coupling

14 Energy Coupling describe the key role of ATP in energy coupling

15 Potential catabolic endergonic catalyst ATP Free Energy

16 Amino acids 20 amino acids Joined together by peptide bonds Amino acid polymer = peptide Structure determines function What element is added in proteins?

17 Primary Structure Secondary Structure Tertiary Structure Quaternary Structure What is the difference between tertiary and secondary structures? explain how the catalytic cycle of an enzyme that results in the production of a final product

18 Enzymes Use your book to define the following Catalyst- Enzyme- Substrate- Active site explain how the catalytic cycle of an enzyme that results in the production of a final product

19 Enzymes Work by decreasing the amount of energy necessary for a chemical reaction to occur. If less energy is necessary, what do you predict will happen to the speed of the reaction?

20 enzyme Active site reactant substrate catalase Activation Energy

21 Enzyme Properties They are proteins Make chemical reaction happen faster Are not used up in chemical reaction (reused many times) Specific to only one kind of substrate Names usually end in ase Ex: lipase, Catalase, lactase

22 Proteins and enzymes are affected by the following: analyze and predict the effect of enzymes in reactions

23 Predict why pH and temperature affect enzymatic activity analyze and predict the effect of enzymes in reactions

24 Competitive and non- competitive inhibitor analyze and predict the effect of enzymes in reactions
