Enzymes Flashcards
1
Q
What are Enzymes?
A
Enzymes: Proteins that speed up reactions.
2
Q
How Do Enzymes Work?
A
Substrate: Molecule that reacts.
Active Site: Where the substrate fits.
Product: Molecule made after the reaction.
3
Q
Temperature & Enzymes
A
Optimum Temperature: The best temperature for the enzyme (37°C in humans).
Too Hot: Enzyme loses its shape (denatures).
Too Cold: Reaction is slow.
4
Q
pH & Enzymes
A
Optimum pH: Best pH for the enzyme. 7
Too High/Low pH: Changes the enzyme’s shape (denatures).
5
Q
Examples of Enzymes
A
Pepsin: Works in acid.
Amylase: Works in neutral pH.
Trypsin: Works in alkaline.
6
Q
- Enzyme Action
A
Enzymes help molecules react faster without being used up.
