|
Definition
1. Energy: the ability to "do work".
2. Systems and interactions: all organisms are interacting systems and all interact with each other.
3. Unity within diversity: at basic level, all organisms are the same.
4. Homeostasis: internal balance.
5. Evolution: change over time. |

Term
| What are the classes of organic compounds? |
|
Definition
| Lipids, proteins, carbohydrates, and nucleic acids. |
|
|
Term
| What are the properties and uses for Carbohydrates? |
|
Definition
| Carbohydrates are sugars. There are 3 types of carbs. Monosaccharides, dissacharides, and plysaccharides. |
|
|
Term
| What are the properties and uses for proteins? |
|
Definition
| Proteins are the building blocks of all organisms. they are made of long chains of amino acids (the monomer unit of proteins). There are 20 different amino acids. A special type of protein is called an enzyme. |
|
|
Term
| What are the properties and uses for lipids? |
|
Definition
| Lipids are fatty organic molecules that contain a large portion of carbon and hydrogen bonds, with very little oxygen. They are insoluble in water. There are 3 types of lipids: fats, oils, and waxes. Their purpose is long term for storing energy and insulation/protection |

|
|
Term
|
Definition
| They are a special type of protein. Their purpose is to speed up chemical reactions. They are specific to certain reactions and many end in the letters '-ase'. They will break down at high temperatures or two high/ too low pH. The 'Lock and Key' theory is substrate fits into the active site of an enzyme like a lock fits into a key. |

Term
| What does it mean to denature an enzyme? |
|
Definition
| Denaturing an enzyme means "unwrapping" it and basically making it non-functional. |
|
|
Term
| What are some things that will denature an enzyme? |
|
Definition
1. High temperatures
2. Change the pH (each enzyme has a different level that would make it unravel)
3. And salt concentrations |
