2

Maltase is in your salvia and starts the breakdown of the sugar maltase in the food you eat.  In this case maltase is ______________________ and maltose is the ______________________ 

Other Answer Choices:

substrate

enzyme

Nitrogen
Carbon
Oxygen
Sulfur
Helium
Phosphorus
Hydrogen
Cadmium
Sodium

Found in ALL organic molecules
Primary elements found in some combination in organic molecules (biomolecules)

Match the monomer to the biomolecule

Draggable item		Corresponding Item
Fatty acid, glycerol		Carbohydrate
Peptide		Lipid
Monosaccharide		Nucleic acid
Nucelotide		Protein

Match the function to the biomolecule. There are no duplicates, each item fits in ONE category

Catalyzing
Steroids - chemical messengers
Allowing movement
Generate energy
Form exoskeletons in some animals
Defending
Make cell walls rigid in plants
Transportation of molecules
Form cell membranes
Starches Store Energy
Transmit genetic information
Triglycerides store energy

Carbohydrates
Proteins
Lipids
Nucleic Acids

Label the reactants and products in the equation

Other Answer Choices:

reactants

products

A biochemical reaction is a reaction that takes place outside a living organism.

True

False

Activation energy is

A made up word

Always the same

How much energy is needed to start a reaction

How much energy the reaction uses total

All reactions need energy to start because

the molecules need to separate to react

the molecules need to touch to react

Enzymes are lipids

True

False

Enzymes speed up a reaction

True

False

Enzymes lower the activation energy of a reaction

True

False

Label the parts

Other Answer Choices:

Enzyme

active site

substrate

Amylase is an enzyme in the liver. When a body overheats, the enzyme doesn't work properly. This is because the enzyme denatured which means

it is not at the right pH any more

it lost speed

it works better

it is not folded in the right shape any more
