Q

What type of energy are Lipids used for?

A

Long term energy

32
Q

What does the body use Lipids for?

A

Cell membranes, hormones, insulation, cushion

33
Q

Where are Lipids digested?

A

Small intestine

34
Q

Saturated fats

A

solid at room temp, animals - bacon, beef, lard - single bonds between all Carbons - hydrogen atoms at all possible places on carbon backbone

35
Q

Unsaturated fats

A

liquid at room temp, plants - corn oil, peanut oil - will have double bonds between carbons, thus fewer Hydrogens

36
Q

Trans fats

A

man made solid fat - oil turned into solid - margerine and shortening

37
Q

Why are trans fats bad for your health?

A

Sticks to artery walls, causes narrowing of arteries; increased blood pressure

38
Q

Anabolic

A

build molecules - estrogen, progesterone, testosterone

39
Q

Catabolic

A

break molecules down -anti - inflamatory steroid - cortisone, prednisone

40
Q

What are nucleic acids used for?

A

DNA, RNA, and ATP

41
Q

DNA

A

deoxyribose, double stranded, instructions on how to make protein, stays in the nucleus

42
Q

RNA

A

ribose sugar, single stranded, does what DNA tells it to - move around in the cell

43
Q

Where are nucleic acids digested in?

A

The small intestine

44
Q

Dehydration Synthesis

A

BUILDING MOLECULES - BY FIRST REMOVING A WATER anabolic PROCESS

45
Q

Hydrolysis

A

BREAKING MOLECULES BY ADDING WATER - CATABOLIC REACTION

46
Q

Properties of water

A

Cohesion, Adhesion, Thermal Properties, Solvent Properties

47
Q

How far is each level on the pH scale?

A

10x the next number

48
Q

Donate H+ in water

49
Q

Gain H+ in water

50
Q

Neutralization Reaction

A

Acid + Base = Salt + Water

51
Q

How do water molecules bond?

A

Positive Hydrogen to Negitive Oxygen

52
Q

What do buffers do?

55
Q

Caused by acidosis

56
Q

Causes Alkadosis

A

Kidney failure, UTI, Vomiting, Gastric Suction

58
Q

Insulin is produced by

A

Beta cells
