Q

Which one of these in not a polymer?

A

Lipids

2
Q

Do these represent monomers or polymers?

(triose, pentose, hextose sugars)

A

Monomers

3
Q

What are monomers of Carbohydrates called?

A

Simple Sugars or Monosaccharides

4
Q

What are polymers of simple sugars called?

A

Polysaccharides Disaccharides

5
Q

Polysacchrides =
Hundreds or thousands of
Monosacharides.

Disaccharides = 2 monosaccharides

A

Reference material

6
Q

What is OH Hydroxyl group look like?

A

-OH

7
Q

What does a keytone look like?

A

>C=O

8
Q

What does a aldehyde look like?

A

H>C=O

9
Q

Energy storage differences in plants and animals are…?

A

Plants: starch
Animals: Glycogen
Glycogen more branched than starch

10
Q

If glucose is all facing the same
direction in a chain, what will
happen to the shape of the
polysaccharide?

A

Curve

11
Q

What about if Glucose is oriented
Back and forth?

A

Straight

12
Q

If curved…. (forms helix)

  • starch or glycogen( more branched)
  • alpha glucose monomers
  • Hydroxyls point in same direction
  • curved is makes easier to break down sugars
  • used to store sugars
A

13
Q

If strait…. (like a string)

  • cellulose
  • beta glucose monomers
  • Hydroxyls orient back and forth
  • strait good for structure (harder to break down)
  • in plant cell walls
A

14
Q

What makes chitin unique and what can it be used for?

A

Because it is structural and digestible. Used in dissolvable stitches

15
Q

Why are lipids not soluble in water?

A

They are non-polar and water is polar

16
Q

What are lipids soluble in?

A

In nonpolar solvents

17
Q

Lipids are soluable in water. True or False

A

FALSE

18
Q

Lipids are polymers. True or False

A

FALSE

19
Q

Lipids hate water and are hydrophobic. True or False

A

TRUE

20
Q

What are the 3 classes of lipids?

A
  1. Fats (energy storage)
  2. Phospholipids (membranes)
  3. Steroids (hormones)
21
Q

Saturated fatty acid have…in regards to carbons

A

no double-bonded carbons

22
Q

Unsaturated fatty acid have…in regards to carbons

A

one or more double-bonded carbons

23
Q

Differences between saturated and unsaturated fats

A

Saturated fat
no double-bonded carbons in any fatty acids
tend to be solid at room temperature
animal fats
strait
Unsaturated fat
one or more (polyunsaturated) double-bonded carbon in the fatty acids
usually liquid at room temperature
plant fats (oils)
kink or bend

24
Q

What if you have only 2 fatty acids attached to a glyceride?

A

Phospholipids

25
Q

In a phospholipid bilayer: Where is it hydrophobic? Where is it Hydrophilic?
Where is it charged? Where is it not charged?

A

Hydrophilic, polar (positive) head; hydrophobic, nonpolar (negative) tail.

26
Q

What is the polymer of protein called?

A

Polypeptide

27
Q

What is the monomer?

A

Amino acids

28
Q

How many naturally occurring amino acids are there?

A

20

29
Q

What is one or more polypeptide chains folded in on each other?

A

Protein

30
Q

True or False: amino acids are put together by a dehydration reaction.

A

TRUE

31
Q

What kind of bond does a dehydration reaction form?

A

Peptide bonds

32
Q

Which structure determines the identity of the protein?

A

Primary Structure

33
Q

Why does primary structure determine the identity for the protein?

A

The order of the amino acids determines how the polypeptide chain folds.

34
Q

What forms the different structures of alpha helix and Beta pleated sheets on Secondary Structures?

A

Hydrogen bonding between Carbon and Nitrogen.

35
Q

How is the tertiary structure formed?

A

Interactions of R groups determines folding.

36
Q

What are the proteins used to help in the folding of Tertiary structure?

A

Chaperonins

37
Q

Disulfide Bridge is a covalent bond. True or False?

A

TRUE

38
Q

What is the monomer of nucleic acids called?

A

Nucleotides

39
Q

What is the polymer of nucleic acids called?

A

Nucleic acids

40
Q

What is the main purpose for Nucleic Acids?

A

To contain genetic information

41
Q

2 famous examples of Nucleic acids are?

A

DNA & RNA

42
Q

With Oxygen?

A

Deoxyribose (for DNA); Ribose (for RNA)

43
Q

Nucleotide example involved in Energy: ATP (energy currency of the cell)

A

Food for thought

44
Q

How does ATP become ADP or AMP?

A

Loses phosphates. Starts off with 3

45
Q

Where do the Ribosomes insert themselves in the Rough ER?

A

Into the Lumen or into

46
Q

True or False: Ribosomes are part of the endomembrane system

A

FALSE

47
Q

Bound to ER or free in cytoplasm

A

More reference material I was too lazy to put into questions

48
Q

Where are Ribosomes Formed?

A

Nucleolus of Nucleus

Nucleus is continuous
with ER and is
membrane Bound.

Nucleus is a double
phospholipid bilayer
And has pores.

49
Q

What does the Golgi Apparatus do?

A

Shipping and packaging center

50
Q

What do Lysosomes do?

A

Pretty much a food vacuole
with digestive enzymes.

Breaks down food that is
phagocytosed and breaks down
damaged organelle into recycled
parts.
