Enzymes are named after the substrate they react with - replacing the "ose" with "ase". This is the enzyme that breaks down Lactose.
What is Lactase?
100
The energy needed to start a reaction is called this.
What is activation energy?
100
Enzymes _________ reactions in the cells.
What is speed up?
100

What is the "lock and key" term?

Each enzyme structure is unique for its substrate to fit. The lock must fit the key. 

100

True or False, the Jell-O did NOT set with the canned pineapple?

What is False.

200
True or False: Enzymes are used up during their reaction.
What is False? Enzymes do not get used up. They are free to react again and again. This is why they are only need in the body in small amounts.
200
True or False: All reactions require the same amount of ENERGY to get started.
What is false?
200
Enzymes are this type of macromolecule.
What is proteins?
200

If an enzyme were to denature how would this affect the lock and key method? 

If an enzyme were to denature, the enzyme can become misfolded, its shape would change, and the key would no longer fit the lock. 

200

What is the enzyme found in fresh pineapple called?

What is Bromelain.

300
Explain what is meant by "Enzymes are substrate specific"
What is they only react with certain substrates that fit into the active site. Think Lock and Key!
300
This protein will reduce the activation energy.
What is an enzyme?
300
Enzymes lowers activation energy & speeds something up. Another word for this is a ____________.
What is catalyst?
300

The balance and stability that our body maintains to function properly is called . . . 

What is homeostasis.

300

Why did the Jell-O not set with the fresh pineapple?

The bromelain enzyme was active and ate away at the Jell-O proteins, not allowing it to solidify.

400
Describe the Lock and Key hypothesis using the terms substrate and enzyme. Which is the lock, which is the key?
What is Enzymes only react with certain substrates that match their shape correctly. Enzymes are the lock, substrates are the key.
400
An enzyme will ____________ the amount of activation energy required.
What is reduce?
400
Enzymes are substrate specific, this means?
What is Enzymes only react with specific substrates that fit into the active site (Lock and key)
400

What is normal human body temperature?

98.6 deg F or 98.67 deg F

400

Other than temperature, what is at least one thing that can affect enzyme activity?

pH, salinity, chemical, mechanical force, radiation, pressure
500

If there were an increased number of substrates (ie: you ate a large buffet dinner), how would this affect enzyme action?

Enzymes would have to work overtime, at a quicker rate in order to help your body digest increased amounts of food. 

500
Activation energy is the energy needed to start a ________.
What is reaction?
500
True or false: For each reaction, there is a specific enzyme.
What is true?
500

Why is a fever of 107 deg F deadly?

Temperature raises too high, causing enzymes to change shape, denature, and no longer function. Can result in death if not treated. 

500
Heating the canned pineapple caused the bromelain enzyme to boil and die. The term for enzyme's dying is . . . 

What is denature.
