Proteins And Enzymes Flashcards
What determines a proteins shape and function?
The sequence/order of amino acids
The five types of protein are enzyme,….
Enzyme, structural, antibody, hormone, receptor
Enzymes are boilogical….
Catalysts. They speed up chemical reactions
Enzymes bind to what?
Substrates
An enzyme active site is…..to the substrate
Complementary
An enzyme is said to be specific, what does that mean?
The enzyme only binds to it’s complementary substrates and nothing else
Synthesis reactions are when multiple…substrates join together to make one…..product
Smaller larger
Describe a degradation reaction
When a large substrate is broken down into smaller products
An enzyme works….at it’s optimum conditions
Best
What happens to an enzyme if the temperature is below the optimum temperature?
It slows down and doesn’t work as well
When an enzyme becomes too hot it…
Denatures
What happens to an enzyme if the temperature is below the optimum temperature?
It slows down and doesn’t work as well
What happens to an enzyme shape if it becomes denatured?
It is permanently changed, so the substrate no longer fits into the active site. This slows the rate of reaction
If the pH of an enzyme’s environment is too low or high above the optimum what happens?
The enzyme denatures
What does complementary mean in the context of an enzyme and it’s substrate?
The enzyme’s active site and the substrate have matching shapes
