Metabolism - Enzymes, Anabolic Reactions and Catabolic Reactions.
| Question | Answer |
|---|---|
| What is metabolism? | All reactions that take place in cells or organisms that sustain life. |
| Anabolic Reactions are where ......? Energy? Bonds? | Small molecules are joined into larger ones. Energy is required. Bonds are being created. |
| Catabolic Reactions are where .....? Energy? Bonds? | Large molecules are broken down into smaller molecules. Energy is released. Bonds are being broken. |
| Some of the .......... released from ............. ......... is used in ............. ............ | Some of the energy released from Catabolic Reaction is used in Anabolic Reactions. |
| What type of reaction is Photosynthesis? | Photosynthesis is an Anabolic Reaction |
| Why? | It builds up larger molecules and uses energy (from the sun) |
| Why specifically? Because it requires energy to change the smaller molecules of ............. .............. and .......... into ........... and the larger molecule of ...........? | It requires energy to change the smaller molecules of Carbon Dioxide and Water into Oxygen and the larger molecules of Glucose. |
| What type of reaction is Cellular Respiration? | Cellular Respiration is a Catabolic Reaction? |
| Why? | It breaks down larger molecules and releases energy. |
| Why specifically? | It releases energy when it breaks down Oxygen and the larger molecule of Glucose into the smaller molecules Carbon Dioxide and Water. |
| Enzymes ......... reactions? | Enzymes activate reactions. |
| A ............. .......... only occurs when there is a ........... amount of ......... to begin the .........? | A chemical reaction only occurs when there is a sufficient amount of energy to begin the reaction. |
| Without .......... the ........... ......... requirement would be low | Without enzymes, the activation energy requirement would be low. |
| Enzymes ......... the amount of ........... .............. to start the ................ that they ...........? | Enzymes decrease the amount of energy required to start the reaction that they catalyze. |
| Enzymes ......... the .... of ....... that occur in ........... .................? | Enzymes increase the rate of reaction that occur in living organisms. |
| What would happen without enzymes? (metabolism, life) | Metabolism would be slow and there wouldn't be enough energy to sustain life. |
