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
