Handout 1/ Sequence 4 Week 1
| Chem Question Seq 4 Wk 1 | Chem Answer Seq 4 Wk 1 |
|---|---|
| Atoms | Made up of smaller particles called Protons, Neutrons, and Electrons |
| Protons have what charge | Positive |

| What are electrons | Negavive charge particles |
| What are two types of bonding between atoms | 1. Ionic 2. Covalent |
| Which bond is stronger - the Ionic or the Covalent | The covalent |
| What are the two distinct areas of study in chemistry | 1. Inorganic 2. Organic |
| What is Inorganic Chemistry | The study of all types of molecules that do not contain carbon atoms |
| What is Organic Chemistry | The study of substances that contain carbon as one of the components of a molecule |
| What are enzymes | Proteins that can regulate the speed of reactions |
| What are catalysts | Protein molecules that speed up reactions by lowering the amount of energy needed to complete the reactions |
| Density | The ratio of mass to volume |
| Electron | Negatively charged particles considered a fundamental unit of matter that exhist independently or outside the neucleus |
| Element | Any of the substances, numbering 107, that cannot be chemically seperated into smaller substances |
| Mixture | The product of mixing two or more items or substances together |
| Molecule | A single atom or several atoms bound together electromagnetically forming the smallest particle that posses all the characteristic physical and chemical properties of an element or compound |
| Neutron | An elementary particle having no charge. Span of 1/2 and mass approximately equal to a proton. Present in the neucleus of all atoms except the common isotope of Hydrogen. |
| Symbol | Represents something else or that stands for complex or abstract concepts |
| Volume | The amount of space occupied by a 3 dimentional object |
| Compound | A substance formed by the union of 2 or more chemical elements in fixed proportions with properties different from those of its constituents |
| Electrolytes | Substances that release ions in water |
| What is an acid | Electrolytes that release hydrogen in water |
| What is a base | Electrolytes that release ions that combine with hydrogen ions |
| The concentration of hydrogen ions in the body fluids effect the chemical reactions that control functions such as | 1. Blood pressure 2. Breathing rate |
| Carbohydrates | Provide energy that cells require and supply materials to build certain cell structures. They are often stored as reserve energy supplies |
| There are 3 necessary macronutrients that provide calories in our diets | 1. Carbohydrates 2. Proteins 3. Fats |
| Carbs provide most of the energy needed in our daily lives for such functions as | 1. Heart rate 2. Breathing 3. Digestion 4. Brain activity |
| carbs are necessary for exercises such as | 1. Biking 2. Running 3. Walking |

| When you eat or drink a simple carb or simple sugar what happens | You feel a sudden spike in blood sugar and then the pancreas will produce additional insulin to remove the excess sugar from your blood |
| What is the sugar craving cycle | As you eat more sugars, there is a sense of needing more fuel, more energy and more calories from the downward spiral. A risidual low blood sugar craving for more of the quick-release, simple sugars |
| As the low blood sugar continues, what happens | The pancreas continues to secret insulin while it simultaneously reduces its production of another hormone called glucagon |
| What is glucagon | The only hormone that allows stored body fat to be released into the bloodstream to be burned by your muscles as energy |
| What happens when the pancreas has to elevate its production of insulin while reducing its supply of glucagon | You are locking-in your excess body fat. Therefore, too much simple sugar intake dramatically hinders the process of reducing stored body fat |
