| 8. What is cellular respiration? What are the raw materials in and products out associated with cellular respiration? |
|
Definition
Cellular respiration converts energy from food into energy stored in ATP.
ATP consists of adenine, a sugar, and 3 phosphate groups.When a phosphate group is transferred from ATP to another molecule (phosphorylation), energy is transferred and ADP is produced. The energy from ATP can power different kinds of work in the cell.As ATP is used in the cell it must be replenished by cellular respiration.
Food energy adds phosphates to ADP molecules to make ATP.

|
|
Term
|
Definition

|
Definition
| Mechanical work, Transport work, Chemical work |
|
|
Term
|
Definition
| The splitting of glucose into pyruvate which helps drive the synthesis of a small amount of ATP. Takes place in the cytosol. |
|
|
Term
|
Definition
| A chemical cycle occurring in the matrix of the mitochondria that breaks the remains of sugars down to produce carbon dioxide. |
|
|
Term
|
Definition
| Process by which plants, along with algae and some bacteria, transform light energy to chemical energy. |

Term
| What is the Calvin Cycle? |
|
Definition
| A series of reactions that occur in the stroma of plants during photosynthesis that utilize NADPH and ATP to reduce carbon dioxide and produce sugars. |

|
Definition
clearing of forests for farming and human settlements
25% of carbon dioxide added to the atmosphere comes from cutting and burning forests in the tropics. |
|
|
Term
| What are some ways in which you can help slow global warming? |
|
Definition
Replanting helps: young trees have faster net photosynthetic rates than older trees.
