Flashcards in Bio Chem Test Part Two: Extra Questions On Nutrition And Reactions Deck (28):
1

There Are Many MacroMolecules Whose Names End In The Suffix "-Ose." These Organic Molecules Are Called

Sugars

2

There Are Many MacroMolecules Whose Names End In The Suffix "-Ase." These Organic Molecules Are Called

Enzymes

3

Name Three Factors That Effect The Rate Of Enzyme Activity

Heat, Tempurature
Amount Of Enzyme
Enough Materials
PH

4

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

Lactase + H2O
Glucose + Galactose

5

What Is The Effect Of Adding Lactase Enzyme To Lactose?

It Helps Lactose Intolerant People Digest Lactose

6

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

7

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

It would speed up

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

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

9

Is There A control in this experiment

Yes

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

Bonds Double Bonds

11

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

Atoms Bonds

12

How many bonds can carbon nitrogen oxygen and hydrogen atoms form

Carbon 4 Nitrogen 3 Oxygen 2 Hydrogen 1

13

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

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

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

15

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

16

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

17

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

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?

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

19

Carbon

Forms 4 Bonds 4 Valence electrons 4 bonds it can make chains in any direction make chains of itself

20

How Many Hydrogen Carbon and oxygen molecules are there in a glucose molecule

12 H 6 O 6 C

21

What is galactose

Monosaccharide

22

What is glucose

27

What is amylose

Polysaccharide

28

What is glycogen

Polysaccharide
