2
2 things that can affect the shape of an enzyme are

pH and Temp

2

The building blocks of proteins are called..

What are amino acids

2
Enzymes _________ reactions in the cells.
What is speed up?
2

This is the term used to describe the interaction involving the substrate and enzyme. The entire process.

What is an enzyme-substrate complex?

2

This bond connects 2 water molecules together

What is hydrogen bond?

4

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.

4

What elements are in an Amino Acid?

What is C, H, O and N?

4
Enzymes are this type of macromolecule.
What is proteins?
4
This is what the Enzyme acts upon.
What is a substrate?
4

This bond connects the oxygen atom to the hydrogen atom in a water molecule

What is covalent bond?

6

Activation Energy is the energy required to start a chemical reaction.  Do enzymes increase or decrease activation energy needed?

What is decrease

6

Lipids have long chains of this element.  It's the most abundant element in organic and inorganic compounds

What is carbon?

6

Enzymes are substrate specific, this means?

What is Enzymes only react with specific substrates that fit into the active site (Lock and key)

6
The “new” substance created during reaction.
What is a product?
6

Water striders and some other insects can stand on the surface of water because of this property of water.

cohesive and adhesive (high surface tension)

8

Catabolic enzyme reactions ________.

What is break down complex macromolecules

8

This macromoleule has a ring like structure

What is glucose/carbohydrates?

8

Enzymes lowers activation energy & speeds something up. Another word for this is a ____________.

What is catalyst?

8
Where the specific substrate fits in the enzyme.
What is an active site?
8

This special property of water that allows water to travel from roots to leaves.

Capillary action

10

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!

McMush Lab showed that all 4 macromolecules were present in the McDouble. What part (ingredient) of the McDouble would you find each of the macromolecules?

Starch in the bread. 

Protein in the patty.

Lipids in the cheese. 

Carbs in the bread.

10

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

What is true?

10
After the reaction, the enzyme is _________.
What is reusable?
10
Why is water polar? Be specific!

There is an unequal sharing of electrons between the atoms and unsymmetrical shape of the molecule.The oxygen has a partial negative charge and the hydrogen has a partial positive charge with water having a bent shape.
