1 Unit 3: Biochemistry Part 1 Review
Nutrition Organic Chemistry Enzymes

2 Lab 3-1: What is in the food you eat?
Experimental Goals Indicator tests Positive and Negative Controls Biochemistry Goals Foods contain biochemical molecules Starch - energy storage molecule Protein - contains amino acids necessary for biosynthesis

3 Journal 3-1: Calculating Nutrients in Fast Foods
Food contains Protein, Carbohydrates and Lipids Recommended intake Vitamins also found in foods

4 Organic Chemistry 4 main types Monomers
Carbohydrates Lipids Proteins Nucleic acids (4th) Monomers Dehydration Synthesis Forms polymers, water produced Hydrolysis Water used, separates polymers Journal 3-2: Molecular Modeling Shape controls function

5 Journal 3-3: Protein Folding
Shape controls function Protein shape is determined by… Amino acid sequence Variable group chemical property

6 Enzymes Enzymes are a type of protein Substrate Products Active Site
Help carry out biochemical reactions Involved in chemical digestion Substrate Products Active Site

7 Journal 3-4: Enzyme Structure Function
Substrate Product Sucrase Sucrose Fructose + Glucose Sucrose Glucose Fructose Sucrose Glucose Fructose Sucrase Sucrase Sucrase Sucrase

8

9 Lab 3-2: Enzyme Action Substrate Product Hydrogen Peroxide
Catalase Hydrogen Peroxide Water and Oxygen Enzyme Function is affected by Temperature pH Surface Area

10 Lab 3-3: You are what you eat
Digestion Saliva contains an enzyme that breaks down starch Biosynthesis Protein is a source of amino acids Amino acids are assembled into proteins in our cells Enzyme Substrate Product Amylase Starch Glucose

11 Digestive System Notes
11 structures Path of food through the digestive system Location of chemical and mechanical digestion Location of absorption

12 Journal 3-5: Digestive System Practice
Digestive tract organs vs helper organs Location of digestion Proteins Carbohydrates Lipids Enzymes involved Amylase, Pepsin, Lipase, Sucrase, Lactase

13 Journal 3-6: Thiamin Deficiency Case Study
Coenzymes affect enzyme function Coenzymes are often vitamins Vitamins are in the food we eat
