M3. Model of Enzyme action

Question 1

2 Models of Enzyme action?

Answer 1

1. lock-and-key model
2. induced-fit model

Question 2

• enzyme’s structure that is involved in catalysis
• three-dimensional entity formed by groups that come from different parts of the protein chains
• center of activity

Answer 2

Enzyme active site/catalytic site

Question 3

• intermediate reaction species that is formed when a substrate binds to the active site of an enzyme.
• causes activation and interaction that leads to conversion of substrate into a product.

Answer 3

Enzyme-Substrate Complex

Question 4

True or False?

Every Enzyme is built specifically for a given Substrate.

Answer 4

True

Sobbing T^T HAHAHAHA. Biochem making me feel single also T^T

Question 5

• ACTIVE SITE: fixed, rigid, geometrical conformation
• SUBSTRATE: complementary geometry

kung here meant to be.

explained by?

Answer 5

LOCK-AND-KEY MODEL

Emil Fischer, 1894

Question 6

• ACTIVE SITE: dynamic.
• Enzyme is flexible.
• adapts the incoming substrate

here nag-aadjust si enzyme para fit sila. Sapilitan yarn? CHAR XD

Answer 6

INDUCED-FIT MODEL

Daniel Koshland, 1958
