IMPORTANT!!!!!

1. IMPORTANT!!!!! • If you will give me every bit of your attention these next 6 days and do the work I ask you to, you will be prepared for the EOC. You can decide now that it is worth the effort, no matter what you have done the last 6 6weeks. • So “put on your thinking caps” 

2. EOC review Day 1 • Biochemistry and scientific method • Handout supplement material for scientific method, microscope and graphs • Pass out spark charts • Have them highlight what I have highlighted on my key – these are areas to revisit • Take down the following notes, study them and use them to help answer the practice questions

3. Monomer- is a smaller unit • Polymer – is the larger unit made of a bunch of smaller units. • Monomer- just one bead • Polymer- two or more beads placed on a string to make a bracelet. • Remember CHO, CHO, CHON, CHONP

4. Nucleotide structure • Sugar • Phosphate • Nitrogen base

5. Enzymes are proteins that speed up a chemical reaction by lowering the activation energy • Endergonic- energy is released or lost • Exergonic- energy absorbed or used

6. Independent variable- variable changed on purpose, the one manipulated – the if part of the hypothesis • Dependent variable- variable that changes in response, the one measured- the then part of the hypothesis • Eating better will make me healthier. • Change to if, then… If I eat better, then I will be healthier. • Independent: eat better • Dependent: amount of health
