Q

What is the definition of enzymes?

A

Enzymes are specialized macromolecules that speed up chemical reactions in cells

32
Q

What are specialized macromolecules that speed up chemical reactions in cells?

33
Q

What is the process of dehydration synthesis?

A

It is the joining of monomers together that creates polymers, takes away water

34
Q

Is it called when monomers join together and create polymers

A

Dehydration synthesis

35
Q

Is the process of hydrolysis

A

Hydrolysis is the breaking apart a polymers into monomers, adds water to break apart polymers

36
Q

Is the breaking apart a polymers into monomers

A

Hydrolysis

37
Q

What is the chemical formula for carbohydrates

38
Q

What does CHO stand for

A

Carbohydrates

39
Q

What are carbohydrates

40
Q

What is a monosaccharide?

A

Monosaccharide is one sugar such as glucose, fructose, galactose. It is made of the hydroxyl group and carbonyl group. It is the carbohydrate monomer/single unit sugar.

41
Q

What is a disaccharide?

A

Cells construct a disaccharide from two monosaccharide monomers by a dehydration reaction. Examples of disaccharide are sucrose, lactose, maltose.

42
Q

What is a polysaccharide?

A

Polysaccharides are macromolecules, polymers of hundreds to thousands of monosaccharides linked together by dehydration reaction. They may function as storage molecules or a structural compounds. Examples are starch, glycogen, cellulose.

43
Q

What involves “ose” and “ase”

A

Sugar and enzymes

44
Q

What are the functions of carbohydrates?

A

To have energy and build structure

45
Q

What are the three types of lipids

A

Fats, phospholipids, sterols

46
Q

What are the two types of fats

A

Fatty acids, triglycerides

47
Q

Is the difference between saturated and unsaturated fats and trans unsaturated fat’s

A

Saturated fats are solids and full of hydrogen, unsaturated fatty acid’s are oil/liquids and are bent, trans unsaturated fatty acid’s are bad except increase shelf life

48
Q

Explain a peptide bond

A

Amino acid go through dehydration synthesis and went to our joint they create a dipeptide bond when another one or more are joint to those two amino acids becomes a polypeptide.

49
Q

Are the four steps to having an amino acid become a protein?

A

Primary: amino acid sequence/polypeptide chain
Secondary: folding a peptide chain into beta sheet or alpha helix
Tertiary: three-dimensional folding of beta sheet or alpha helix
Quaternary: collection of tertiary structures into a specific shape

50
Q

Are the seven functions of proteins

A
  1. Structural
  2. Contractile
  3. Defensive
  4. Signal
  5. Receptor
  6. Transport
  7. Storage
51
Q

What are examples of the functions of protein?

A
  1. Structural: bones
  2. Contractile: muscles
  3. Defensive,: white blood cells
  4. Signal proteins: lipid/hormones
  5. receptor: outside of cell
  6. Transport: hemoglobins
  7. Storage: food vacuoles
52
Q

What specific part of a protein is important and determines the function

53
Q

What does shape determine

54
Q

What does DNA stand for

A

Deoxyribonucleic acid

55
Q

What does RNA stand for

A

Ribose nucleic acid

56
Q

What is the definition of transcription

A

First step of gene expression, DNA is opened by the enzyme RNA polymerase and DNA is copied into RNA.

57
Q

What is the definition of translation

A

Process of converting our night into a polypeptide chain using a ribosome

58
Q

What is the first step of gene expression, DNA is opened by the enzyme RNA polymerase and DNA is copied and RNA

A

Transcription

59
Q

What is the process of Converting our chain into a polypeptide chain using a ribosome

A

Translation

60
Q

What compound is only made of hydrogen and carbon?

A

Hydrocarbon

61
Q

This hydrocarbon made out of

A

Hydrogen carbon

62
Q

Explain the different structures of carbon

A

There carbon rings in their chains versus branching branching involves double bonds

63
Q

Splaine dehydration synthesis and hydrolysis with carbohydrates, lipids, proteins and nucleic acid

A

All of them involve both dehydration synthesis and hydrolysis, but protein has a special name to call the peptide bond

64
Q

What are examples of the functions of carbohydrates

A

Monosaccharides and disaccharides give energy and polysaccharides build structure

65
Q

Is a triglyceride made of

A

Glycerol and fatty acids

66
Q

There’s a phospholipid made of

A

Phosphate group and fatty acids

67
Q

What is the composition of an amino acid

A

Amino group, alpha carbon, carboxyl group, side chain

68
Q

What is denature

A

Polypeptide chain is unraveled and it loses specifics shape and function

69
Q

Is it called when a polypeptide chain unravels and loses its specific shape and function

70
Q

Why does denaturation happen

A

When the proteins break down due to heat or change in pH

71
Q

When does hydrolysis occur

A

It only occurs with a circle enzyme

72
Q

What is the composition of nucleotides and what differentiates them

A

Phosphate, sugar, nitrogenous base: back bone — the base creates A hydrogen bond

73
Q

What is the function of a nucleic acid

A

Storage of genetic code and protein synthesis

74
Q

What is DNA

A

It is double stranded and double helix

75
Q
