| What is the difference between an atom and a molecule? | An atom is a single atom, made from protons, neutrons and electrons. A molecule is a group of atoms bonded together. |
| Using the periodic table, how do you find the # of protons? | You look at the atomic number |
| Using the periodic table, how do you find the # of electrons? | It would be the same number as the protons. |
| Using the periodic table, how do you find the # of neutrons? | You take the atomic weight and round it to the nearest whole number. Then you subtract that number with the atomic mass |
| What is the difference between mass number, atomic mass? | Mass number is the number of protons and neutrons in an atom. Atomic mass is the average mass. |
| How many electrons are in this atom? | 3 |
| How many neutrons are in this atom? | 4 |
| This is an atom of which element? | Lithium |
| What is a macromolecule? | A molecule that contains a large number of atoms |
| What is so simple about simple sugars? | They have a lot of sugar |
| What is so complex about complex carbohydrates? | They have a lot of carbs. |
| For what three reasons do you need lipids in your body? | |
| Using a picture how can you tell the difference between a carbohydrates and a lipid? | the atoms |
| Using a picture, how can you tell the difference between an unsaturated and saturated fatty acid chain? | they have different bonds |
| What is so complete about complete proteins? | contains all 9 essential amino acids |
| how do vegetarians/vegans get all nine essential amino acids from incomplete proteins? | from veggies and proteins bean or nuts |
| How do you get nucleic acids from food? | previous living things |
| Carbohydrates monomer | monosaccharides |
| Carbohydrates polymer | polysaccharides |
| Lipids monomer | fatty acids, Glycerol |
| Lipids polymer | Trigylceride |
| Proteins monomer | Amino acids |
| Proteins polymer | Polypetide |
| Nucleic acids monomer | Nucelotide |
| Nucleic acids polymer | nucleic acid |
