Biology: Macromolecule Review Worksheet Name:

A. Visit this site:

Follow the instructions for a review of macromolecules of life

B. Answer the following questions.

| [pic] | 1. Connect these two boxes by circling |

| |the correct arrow. Write beneath the line |

| |how these two are connected. |

| [pic] | 2. How do the circles to the left relate |

| |to the boxes above? Use the same types of |

| |arrows. Start with the circles and draw |

| |right up to the boxes above, where it is |

| |appropriate. Then explain your thoughts in|

| |the space beneath the line. |

|  | 3. How are these boxes to the left |

|[pic] |related to the cellular structures listed |

|  |in the circles? |

|[pic] | |

| |Draw arrows between the boxes and the |

| |circles and explain your thoughts on their|

| |relationships in the space at the bottom |

| |of the page. |

4. Some people say life is fundamentally all structured the same, while others say there is great diversity even in very small molecules. What do you think and why?

5. These molecules represent one level of basic building blocks of life. These monomers, or single molecules, can be joined with other monomers to form larger units (polymers). They can be divided into four groups: carbohydrates (sugars for energy and structure), lipids (fats for membranes and energy storage), nucleic acids (information bearers) and proteins (the molecular machines of the cells). Even if you have never had ANY chemistry at all, you can work on this activity! Try to determine some ways of dividing these molecules below into four groups. There may be more than one right answer. Number each molecule either 1, 2, 3 or 4.

6. What different kinds of atoms are present in the previous molecules?

7. Imagine that an unwanted bacteria invades a cell. A certain molecule in the cell is capable of grabbing the bacteria and holding it so a bacteria-destroying macrophage can destroy it. Describe the properties and the forces of the "bacteria-capturing" molecule that enable it to attach and hold the invader.
