Macromolecules
Question | Answer |
---|---|
smaller molecules joined together to make a larger molecule that helps the cell do what it needs to do | macromolecule |
Nucleic acid made by DNA. It makes protein. | RNA |
Formed by long chains of nucleotides that passes genetic material from parent to offspring | nucleic acid |
Formed by long chains of amino acids Help cells communicate and break down nutrients in food. | protein |
Does not dissolve in water Protects cell and large part of the cell membrane. Stores energy for cells and help with the cell communication. | lipids |
cholesterol phospholipids vitamin A | lipids |
Examples are : RNA DNA | nucleic acids |
Examples are : sugar starches cellulose | carbohydrates |
made of long chains of sugars Helps the cell to communicate, provide structural support, stores ennergy | carbohydrates |
all living things are made of cells, the smallest living this is a cell, and cells are made from pre-existing cells | cell theory |
large molecules help the cell to: communicate structural support protection transport genetic material growth move materials | macromolecules |
cell without a nucleus | prokaryote |
cell with a nucleus | eukaryote |
cell that has organelles without membranes like ribosomes | prokaryote |
cell that has membranes around the organelle | eukaryote |
a bacteria cell is an example | prokaryote |
animal , plant, some protists are examples | eukaryotes |
calcium | builds strong bones and teeth |
Iron | helps carry oxygen throughout the body |
carbon | found in all macromolecules; all living things contain |
Phosphorus | found in DNA and nucleic acid |
Potassium | lowers blood pressure and prevents strokes |
inorganic | does not contain carbon |
organic | contains carbon |
