Unit 1- Enzymes Flashcards
What are enzymes classifies as
Biological catalysts
Why do all living cells contain enzymes
To speed up the rate of reaction
What are enzymes made of
Protein
What are the substances enzymes act in called
Substrates
What do enzymes produce when they act in substrates
Products
What is the area where the substrate binds to a substrate called on an enzyme
Active site
Why are enzymes considered specific
Enzymes are considered specific because the shape of their active site is complementary to the shape of it’s specific substrate.
What happens to the enzymes after the substrate is converted into products?
It remains unchanged and can combined with another substrate
What are the two types of enzyme reactions?
- Degradation reaction
- Synthesis reaction
What happens in a degradation reaction
A degradation reaction is where one large substrate is broken down into smaller products
What happens in a synthesis reaction
A synthesis reaction is where small substrates are built up into a larger product.
What is meant by an optimum condition
A condition (temp. /pH) which enzymes are most active at.
What is the optimum temp for human enzymes
37C
What does it mean when an enzyme is denatured
Change in shape in the enzyme’s active site, meaning it can no longer bind to its substance furthermore, affecting the rate of reaction
When does an enzyme become denatured
An enzyme will denature when it’s exposed to an incorrect pH or high temperature.
