Enzymes Flashcards
Enzymes are made out of…
Proteins / amino acids / peptides
Lactose is to lactase as lipids are to…
Lipase
Enzymes are biological CATALYSTs because…
They increase the rate of reaction of different reactions in the body and are not affected/used up in the process.
Catabolic enzymes are for…
Breaking down substrates
Anabolic enzymes are for…
Forming a product from substrates
The substrates form what type of bonds with the active site?
Hydrogen bonds
The name of a bound substrate to an active site in the ‘lock and key theory’:
Enzyme-substrate complex
What are the 2 methods to enzyme action
i) Lock and key theory
ii) Induced fit theory
The enzyme’s active site is completely complementary to the substrate:
Lock and key theory
The active is not fully complementary to the substrate. The substrate induces the active site bonding:
Induced fit theory
5 factors affecting enzyme reaction:
i) Temperate
ii) pH
iii) Substrate concentration
iv) enzyme concentration
v) Inhibitors
Explain the Q10=2 rule
For every 10 degree rise the rate of reaction doubles
Inhibitors are:
Molecules that bind to an enzyme which inhibits an enzymes reaction.
