| Question | Answer |
|---|---|
| molecule | group of atoms that are held together by covalent bonds |
| organic molecule | bonding that occurs between 2 or more carbon atoms |
| carbohydrates | organic marcromolecules that are made of carbon hydrogen and oxygen |
| simple carbohydrates | monosaccharides |
| monosaccharides | glycose, fructose, and ribose |
| monosacharides can be: | combined to form polysacharides |
| nucleic acids | form nucleotide monomers |
| nucleotides | chemically compounds that contain hydrogen, oxygen, nitrogen and phosphorus |
| main types of nucleic acids | RNA and DNA |
| carbs ratio: | 1 carbon atom: 2 hydrogen atoms: 1 oxygen atom |
| may be simple or complex | carbs |
| The presence of multiple carbon-hydrogen bonds within carbohydrates makes them an excellent source of energy | carbs |
| polysacharide examples | Glycogen, starch, and cellulose |
| used for long term energy storage | polysacharides |
| cellulose | found in cell wall of plants |
| They consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups. | nucleotides |
| contains ribose | RNA |
| contains deoxyribose | DNA |
| stores genetic information and encodes the sequences of all the cell's proteins. | DNA |
| involved in the direct production of the proteins. | RNA |
| different because the sequence of nitrogenous bases that they contain are different. | nucleic acids |
| five nitrogenous bases found in nucleic acids. | Adenine (A), cytosine (C), and guanine (G) are found in both DNA and RNA. Thymine (T) is only found in DNA, and uracil (U) is only found in RNA. |
| lipids | organic macromolecules that are insoluble in water |
| fats | most important lipids |
| triglycerides | type of fat that contain one glycerol molecule and three fatty acids. |
