Organic Chemistry
Question | Answer |
---|---|
What are 3 examples of carbohydrates in food? | Bread, potato, pasta |
What is the monomer of a carbohydrate? | Monosaccharide |
What is the monomer of a protein? | Amino acid |
What elements make up most organic molecules? | CHO (carbon, hydrogen, oxygen) |
What are the monomers of nucleic acid? | Nucleotides |
What is the process of joining monomers to build a carbohydrate or protein called? | Dehydration Synthesis |
How does dehydration synthesis work? | Water is removed from the molecule to attach monomers |
What is the process of breaking down a carbohydrate or protein into smaller monomers? | Hydrolosis |
How does hydrolosis work? | Water is added to split a disaccharide |
What is the function of a monosaccharide? | Main fuel that cells use for cellular work |
What is the function of a disaccharide? | This is a transport sugar for plants because it is too large to fit into cells |
What is the function of a polysaccharide? | Energy storage and structure |
What energy storage polysaccharide do we use? | Glycogen |
What energy storage polysaccharide do plants use? | Starch |
What structural polysaccharide do we use? | Chitin |
What structural polysaccharide do plants use? | Cellulose |
What is the difference between an organic and inorganic molecule? | Organic molecule contains carbon, inorganic does not |
How many carbon bonds can be made with other elements? | 4 |
What are polymers made up of? | Monomers |
Monomers are linked together to make what? | Polymers |
What are the four classes of organic molecules? | Carbohydrates, lipids, nucleic acid, and protein |
What is a saturated fat? | Glycerol molecule which have all single carbon-carbon bonds and the chain is saturated with hydrogen. The molecule can copy the shape of its neighbor. |
What is an unsaturated fat? | Glycerol molecule which have one or more carbon double bonds in the chain. The molecule can not copy the shape of its neighboring chain. |
What state of matter is a saturated fat at room temperature? Why? | Solid; Each lipid can copy the shape of its neighbor causing layering, thus making it solid. |
What state of matter is an unsaturated fat at room temperature? | Liquid; Each lipid can not copy the shape of its neighbor and therefore cannot layer, making the fat liquid. |
What is an example of a saturated fat? | Butter |
What is an example of an unsaturated fat? | Plant oil |
Which organic molecule has the greatest energy per gram? | Lipids (Twice as much) |
What is the function of a glyceride? | Long term energy storage |
How does glyceride help animals like whales and polar bears? | Insulation |
Where is glyceride stored in animals? | Fat |
Where is glyceride stored in plants? | Seeds |
What is the function of phospholipids? | Make cell membrane |
What are the two ends of a phospholipid? | One is hydrophillic (charge) and one is hydrophobic (no charge) |
What is the function of waxes? | Plant leaves are covered with wax to help conserve water |
What are steroids used for? | Steroids are hormones that determine physical development |
How many types of amino acids are used in living things? | 20 |
What is the function of proteins? | Structure and chemistry |
What is the role of singular nucleotides? | Temporary energy storage |
What is the function of DNA? | Makes proteins |
What is the function of RNA? | Assisting DNA in making of proteins |
What is the chemical formula of a monosaccharide? | C6 H12 06 |
What is a double helix? | DNA |
What are the three parts of a nucleotide? | 1)A five carbon sugar 2)A base that has nitrogen atoms 3)An ion of phosphoric acid known as phosphate |
Why do companies still use trans fat even if it's bad for you? | Long shelf life |
How is trans fat made? | Double bonds of unsaturated fat are broken |
What is atherosclerosis? | Hardening of the arteries due to plaque buildup. |
Are LDL or HDL better for you? | HDL |
