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?

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.
