CB - Enzymes
Cell Biology - Topic 5 - Enzymes
| Question | Answer |
|---|---|
| Which type of cells make enzymes? | All living cells |
| What do enzymes function as? | Biological catalysts |
| What is the molecule called that an enzyme works on? | substrate |
| At what area on the enzyme does the substrate bind to? | active site |
| Enzymes are only complementary to ONE substrate, this is known as? | specific |
| What word describes reactions that build small substrates into a large products? | synthesising |
| What word describes reactions that break down a large substrate into smaller products? | degrading |
| What enzyme breaks starch down into maltose? | amylase |
| What enzyme breaks down hydrogen peroxide into oxygen and water? | catalase |
| What enzyme breaks down protein into amino acids? | pepsin |
| What enzyme breaks down fat into fatty acids and glycerol? | lipase |
| What enzyme builds glucose-1-phosphate into starch? | phosphorylase |
| What are 'optimum conditions' for enzymes? | the conditions in which the enzyme is most active. |
| What conditions could denature an enzyme? | High temperature, pH |
| What happens to a denatured enzyme? | The shape of active site changes, so the enzyme no longer works |
| What is the function of enzymes? | They are biological catalysts that speed up chemical reactions but are unchanged in the process. |
| What is the complex called when a substrate binds into the active site of the enzyme? | An enzyme-substrate complex. |
| If an enzyme becomes denatured will this increase or decrease the rate of reaction? | Decrease (slows down the reaction) |
