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
Enzymes in the human body typically operate best at this pH

What is a pH of 7

100

What is the largest ocean on Earth

Pacific Ocean

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
On the pH scale, this is the most Basic a substance can be. What is the pH number?

What is pH 14

Which Planet is known as the Red Planet

Mars

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

An enzyme's active cite changes shape and can no longer accept a substrate

What is denaturing?

300

Which US State has the most active volcanoes

Alaska

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

A allosteric (non-competative) inhibitor perminantly changes the shape of an enzyme (True or False)

What is False

400

What year was the very first iPhone released?

2007

500
Describe the differences between a synthesis reaction and a hydrolysis reaction.
What is: synthesis is a building up reaction (2 substrates join into one) hydrolysis is a breaking down reaction involving water (1 substrate breaks into two)
500
Activation energy is the energy needed to start a ________.
What is reaction?

True or false: For each reaction, there is a specific enzyme.
What is true?
