22
Q

How do enzymes work

A

The substrate binds with the enzyme in the active site to create an enzyme-substrate complex, then the reaction causes the substrates to weaken and eventually combine forming a new substance called the product before being released from the enzyme.

23
Q

Compare glucose and fructose

A
  • Differences
    1. Glucose is arranged in a hexagon while fructose is arranged in a pentagon.
    2. Fructose is sweeter than glucose.
  • Similarities
    1.They are both carbohydrates and monosaccharides
    2.They have the same formula
24
Q

Compare carbohydrates and lipids

A
  • Differences
    1. Lipids are used for thermal insulation
    2. Carbohydrates are sugars while lipids are fats, oils, and waxes
    3. Carbohydrates are rings while lipids are chains
  • Similarities
    1.They are both used for energy storage and structural material
25
Q

What allows carbon to be the key element

A

It is small and can have four bonds allowing it to form chains and rings.

26
Q

What do chemical reactions do to atoms

A

Change the arrangements of molecules.

27
Q

What are produced by chemical reactions

A

New substances with new properties.

28
Q

What does it mean for a chemical equation to be “balanced”

A

The same number of atoms on both sides of the equation.

29
Q

What are two examples of activation energy being used

A

An electric spark and the sun shining on a plant.

30
Q

What are some factors that can affect enzyme activity

A

Temperature, pH, and Inhibitors

31
Q

In what ways can an inhibitor cause an enzyme to be ineffective

A

Blocking the active site or changing the shape of it.

32
Q

What are the main elements found in living things

A

Carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus

33
Q

Large molecules formed by joining smaller organic molecules together

A

Macromolecule

34
Q

What are the functions of carbohydrates

A

Energy storage and structural material

35
Q

What types of atoms are found in carbohydrates and what is the basic ratio of these atoms

A

Carbon, oxygen, and hydrogen, C:H:O, 1:2:1

36
Q

How are the carbon atoms arranged in carbohydrates

A

Ring structures

37
Q

What is a monosaccharide and what are some examples

A

Carbohydrates with one carbon ring, glucose and fructose

38
Q

What is a polysaccharide

A

Monosaccharides joined into chain structures

38
Q

What is a disaccharide and what are some examples

A

Two monosaccharides joined to form one molecule, sucrose and maltose

39
Q

Polysaccharides are polymers, what are the monomers that they are made of

A

Starch, cellulose, and glycogen

40
Q

What are some examples of lipids

A

Fats, oils, and waxes

41
Q

What are the functions of lipids

A

Energy storage, structural material, and thermal insulation

42
Q

What is the polymer part of a lipid

A

44
Q

What are the main atoms in lipids

A

Carbon, hydrogen, and oxygen

45
Q

What are the monomers that the lipid polymer is composed of

A

CH₂

46
Q

What are the monomers that proteins are polymers of

A

Amino acids

47
Q

What four things does every amino acid have

A

An amino group, a hydrogen, a carboxyl group, and a variable side chain

48
Q

What are the functions of proteins

A

Structural material and enzymes

49
Q

What is the function of nucleic acids

A

Information storage

50
Q

What are some differences between DNA and RNA

A

DNA contains all the cells genetic information and remains in the nucleus but RNA is copied from the DNA and can leave the nucleus so the information can be used

51
Q

What are the monomers that nucleic acids are polymers of

A

Nucleotides

52
Q
