What is the relationship between enzymes and energy? |
|
Definition
Enzymes help substrates form or break bonds and allows reactions to happen with less activation energy. |
|
|
Term
Why don't enzymes work the same at different temperatures? |
|
Definition
They get denatured at high temperatures, and slow down at low temperatures. |
|
|
Term
How do vitamins help enzymes? |
|
Definition
They help speed up enzymes by bonding with the substrate |
|
|
Term
How does substrate concentration affect enzyme activity? |
|
Definition
The higher the substrate concentration, the faster the enzyme will work, up to a point. |

|
|
Term
What causes proteins to be denatured? |
|
Definition
When they are exposed to high temperatures or extreme pH |
|
|
Term
Why was the marble at the bottom in the second beaker of gelatin which contained Bromelain? |
|
Definition
The proteins were broken down into animo acids. |

Term
In humans, how will enzymes be affected by a fever? |
|
Definition
they will be less effective because a fever makes the body warmer than 37 degrees celsius. |
|
|
Term
Why do organisms lower their body temperature when they hibernate? |
|
Definition
It slows down the enzymes in their bodies so then can survive for longer on less food. |
