Biology Chapter 2
| Question | Answer |
|---|---|
| Carbohydrate | - molecules composed of carbon, hydrogen, and oxygen - include sugar and starches. - CHO, 1:2:1 Ratio, C 6 H 12 O 6 d |
| What are some examples of carbohydrates | - Pasta - Bread - Wheat |
| Monosaccharides | - simple sugars in carbohydrat |
| How many simple sugars are in a carbohydrate | - five or six carbon atoms |
| Monomers | Each subunit in the complete molecule |
| Polymer | Large molecule, or a macro molecule, made of many monomers bonded together. |
| Lipids | -nonpolar molecules that include fats, oils, and cholesterol. -most lipids contain chains of carbon atoms bonded to oxygen and hydrogen atoms. - Some lipids are broken down as a source of usable energy for cell |
| What is the job of lipids | store energy |
| What are fatty acids | are chains of carbon atoms bonded to hydrogen atoms. |
| Protein | - is a polymer made of monomers called amino acids. - CHON |
| What is the job of protein | - Build, Repair, Maintain |
| Amino acids | are molecules that contain carbon, hydrogen, oxygen, and nitrogen, and sometimes sulfur. |
| How many amino acids are used to build proteins | Organisms use 20 different amino acids. Body can make 12 of the amino acids others come from foods such as meat, beans, and nuts |
| Nucleic Acids | - are polymers that are made up of monomers called nucleo tides - CHONP - Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus |
| Nucleotides | - composed of sugar - phosphate group - DNA & RNA. |
| What is the job of Nucleic Acids | - Work together to make proteins. |
| What is the relationship between a polymer and a monomer | - Monomers are sub units many of these monomers make up a large macro molecule called polymers |
| Explain how both nucleic acids and proteins are polymers. Be sure to describe the monomers that make up the polymers | - Both are made up of monomers (protein - amino acids) (nucleic acids- nucleotide) |
| How are carbohydrates and lipids similar? How are they different? |
