What are enzymes |
Globular proteins that act as biological catalysts, speeding up metabolic activity |
|
What are the two models of the active site |
Lock and key theory Induced fit theory |
|
Difference between lock and key and induced fit theory |
Induced fit argues active site is flexible and can change shape slightly fitting more closely around the substrate. |
|
Activation energy |
Energy needed to be supplied before reaction starts |
|
what are the three steps of splitting a substrate molecule? |
1. random movement causes the enzyme and substrate to collide, and substrate enters the active site. 2. Enzyme-substrate complex forms. Charged groups attract, distorting the substrate and aiding bond breakage or formation. 3. products released from the active site |
|
catabolic reactions |
breaking down |
|
anabolic reactions |
building up |
