Question 4

In The Reaction Lactose + H2O -> Glucose + Galactose The Enzyme Lactase Is Involved. What Are The Substrates What Are The Products

Answer 4

Lactase + H2O

Glucose + Galactose

Question 5

What Is The Effect Of Adding Lactase Enzyme To Lactose?

Answer 5

It Helps Lactose Intolerant People Digest Lactose

Question 6

What Is The Chemical Reaction Taking Place When Adding Lactaid To Lactose

Answer 6

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

Question 7

What Would Happen In This reaction if the amount of enzyme were increased

Answer 7

It would speed up

Question 8

Body temp 36.6C What would happen to the rate of this reaction if the temperature of the water bath were decreased to 0C

Answer 8

The reaction slow down because the rate of the molecules would decrease

Question 9

Is There A control in this experiment

Answer 9

Yes

Question 10

What do the lines in a structural formula represent What does it mean when there are two lines between atoms in a structural formula

Answer 10

Bonds Double Bonds

Question 11

In your molecular set, what do the balls or beads represent What do the sticks or tubes represent

Answer 11

Atoms Bonds

Question 12

How many bonds can carbon nitrogen oxygen and hydrogen atoms form

Answer 12

Carbon 4 Nitrogen 3 Oxygen 2 Hydrogen 1

Question 13

What could you do to your models of starch and a polypeptide chain in a protein to make them more accurate

Answer 13

Put them in longer chains sequence them and shrink them

Question 14

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

Answer 14

The Amino acids are able to make these proteins because there are so many possible outcomes for the sequences

Question 15

What is a hydrolysis reaction

Answer 15

Hydrolysis is when a water molecule is added to break a compound apart.
It’s the opposite of dehydration synthesis

Question 16

Why is sucrose less soluble in water than glucose or fructose

Answer 16

Sucrose is less soluble because it’s a dissacharide Glucose and fructose are monosaccharides that combine to make sucrose

Question 17

What is invertase What chemical reaction does it perform

Answer 17

Invertase is an enzyme derived from yeast that causes the hydrolysis of sucrose into fructose and glucose

Question 18

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?

Answer 18

Your Body uses carbohydrates to make glucose your body’s main energy source
Salivary Amylase
Glucose
The mouth
