Cells and chemistry Ch 6.2

A. Reaction format 1. Reactants 2. Yields 3. Products 4. Coefficients, subscripts

2H2O ---> 2H2 + O2 Reactant “yields” Products Large #2 = Coefficient Small #2 = Subscripts

B. Release /absorb energy 1. Constantly 2. Building requires -example

3. Breaking releases -example 4. Metabolism

C. Energy to start 1. Analogy 2. Activation energy 3. Graph 4. Example

D. Enzymes 1. Proteins 2. Lower the a.e. 3. Not altered 4. Catalysts

E. ex: carbonic anhydrase 1. O2CO2 2. Carbonic acid 3. 200/hour w/o 4. 600,000/sec w/

F. Specific binding 1. Substrate 2. Active site

3. Induced fit theory (NOT lock+key ) 4. Pushes or pulls 5. Unchanged

H. Lower effectiveness 1. Optimum range a. Temperature b. pH c. Concentration

2. Examples a. Siamese cat b. Harp seals
