| Question | Answer |
|---|---|
| Simple carbohydrates are made of ___ _____ _________ and are the most ______ ______ source for organisms. | 1-2 sugar molecules; common energy |
| Carbohydrates are compounds made from ______, ________, and ______. | carbon; hydrogen; oxygen |
| What is the general ratio of carbon, hydrogen, and oxygen in carbohydrates? | 1:2:1 |
| What are the building blocks of carbohydrates? | monosaccharides |
| What do monosaccharides (single sugars) usually have? | 5-6 carbon atoms formed in a ring structure. |
| Scientists often leave the corners of shapes empty in chemical/structural diagrams to represent ______ _____. | carbon atoms |
| What do organisms break down carbohydrates into? | Glucose; provides chemical energy to organisms. |
| What monosaccharide is central to all organisms? | Glucose; the main carbohydrate converted into energy. |
| Does glucose bond with itself and other monosaccharides to form other carbohydrates? | Yes. |
| What is a common monosaccharide found in fruits? | Fructose, natural carbohydrate loved by primates, including humans. |
| What has the same chemical form as glucose, but has a different structural form? | Fructose. |
| What does 'DNA' and 'RNA' stand for? | deoxyribonucleic acid; ribonucleic acid. |
| What are deoxyriboses and riboses? | Monosaccharides with 5 carbon atoms. |
| nucleic acids: | Molecules that contain/implement genetic control over cells. |
| What is the function of DNA? | Holds instructions for building proteins. |
| What is the function of RNA? | Integral to the synthesis/organization of proteins |
| What forms when two monosaccharides form a chemical bond? | A disaccharide. |
| What is sucrose? | Table sugar; composed of glucose and fructose. |
| What causes cavities? | The bacteria that feed off left-over sugar on teeth; NOT sugar itself. |
| What is lactose? | Lactose is a dissaccharide sugar found in milk; often used to feed offspring of many mammals. |
| What is lactose comprised of? | Glucose and galactose. |
| Is milk the only natural source of lactose? | Yes. |
| Why are some people lactose intolerant? | These people have a minor chemical structural detail that prevents them from breaking down lactose, making them sick whenever they eat food containing lactose. |
| What is deoxyribose? | A monosaccharide; the sugar component of DNA. |
| What is ribose? | A monosaccharide; the sugar component of RNA. |
