Enzymes Flashcards
What is an enzyme?
A biological catalyst that speeds up chemical reactions in living organisms.
True or False: Enzymes are consumed in the reactions they catalyze.
False
Fill in the blank: The part of the enzyme where the substrate binds is called the ______.
active site
What is the lock and key model?
A model that describes how enzymes and substrates fit together specifically.
Multiple Choice: What factors can affect enzyme activity? A) Temperature B) pH C) Substrate concentration D) All of the above
D) All of the above
Short Answer: What happens to an enzyme after it catalyzes a reaction?
It remains unchanged and can be used again.
True or False: Enzymes can work on multiple substrates.
False
What is enzyme denaturation?
The process in which an enzyme loses its structure and function due to extreme conditions.
Multiple Choice: Which enzyme breaks down starch? A) Amylase B) Lipase C) Protease D) Lactase
A) Amylase
Fill in the blank: The model that explains how enzymes change shape when binding to a substrate is called the ______ model.
induced fit
What is the active site
The groov on an enzyme that the substrate is attracted too
What are proteins broken down by
Protease, they break down the amino acid chain individually
Our body absorbs them and builds its own
What is starch broken down by?
Amylase
Found in saliva and breaks starch into simple sugars
What breaks down lipids
Lipase breaks down lipids and separates the glycerol and fatty acids
What do lipids consist of?
Glycerol, attached to fatty acids
