There Are Many MacroMolecules Whose Names End In The Suffix “-Ase.” These Organic Molecules Are Called
Enzymes
Name Three Factors That Effect The Rate Of Enzyme Activity
Heat, Tempurature
Amount Of Enzyme
Enough Materials
PH
In The Reaction Lactose + H2O -> Glucose + Galactose The Enzyme Lactase Is Involved. What Are The Substrates What Are The Products
Lactase + H2O
Glucose + Galactose
What Is The Effect Of Adding Lactase Enzyme To Lactose?
It Helps Lactose Intolerant People Digest Lactose
What Is The Chemical Reaction Taking Place When Adding Lactaid To Lactose
Hydrolysis Is Used In This Reaction, The Lactase Enzyme Brings The Water And The Lactose Together So A Reaction Can Occur. The Enzyme Essentially Speeds Up The Reaction
What Would Happen In This reaction if the amount of enzyme were increased
It would speed up
Body temp 36.6C What would happen to the rate of this reaction if the temperature of the water bath were decreased to 0C
The reaction slow down because the rate of the molecules would decrease
Is There A control in this experiment
Yes
What do the lines in a structural formula represent What does it mean when there are two lines between atoms in a structural formula
Bonds Double Bonds
In your molecular set, what do the balls or beads represent What do the sticks or tubes represent
Atoms Bonds
How many bonds can carbon nitrogen oxygen and hydrogen atoms form
Carbon 4 Nitrogen 3 Oxygen 2 Hydrogen 1
What could you do to your models of starch and a polypeptide chain in a protein to make them more accurate
Put them in longer chains sequence them and shrink them
There are thousands of proteins in a human cell but only about 20 different amino acids Explain how so few building blocks can be used to make so many different proteins
The Amino acids are able to make these proteins because there are so many possible outcomes for the sequences
What is a hydrolysis reaction
Hydrolysis is when a water molecule is added to break a compound apart.
It’s the opposite of dehydration synthesis
Why is sucrose less soluble in water than glucose or fructose
Sucrose is less soluble because it’s a dissacharide Glucose and fructose are monosaccharides that combine to make sucrose
What is invertase What chemical reaction does it perform
Invertase is an enzyme derived from yeast that causes the hydrolysis of sucrose into fructose and glucose
Why are carbohydrates a necessary macromolecule for survival? What enzyme breaks down starch? What does it break it down into? Where does the breakdown happen?
Your Body uses carbohydrates to make glucose your body’s main energy source
Salivary Amylase
Glucose
The mouth
Carbon
Forms 4 Bonds 4 Valence electrons 4 bonds it can make chains in any direction make chains of itself
How Many Hydrogen Carbon and oxygen molecules are there in a glucose molecule
12 H 6 O 6 C
What is galactose
