BIOL 102 Exam 3 Digestive And Immune
System| All Correct Answers| Update 26
digestive system - Ans--mouth->pharynx->esopaghus->stomach->small
intestine->large intestines
carbohydrates - Ans--monosaccharides, disaccharides, polysaccharides
monosaccharide - Ans--A single sugar molecule such as glucose or
fructose
basic building block of the digestive system
5-6 carbon molecules
chains or ring structure
disaccharide - Ans--2 monosaccharides chemically joined, cannot be
absorbed, must be broken down into monosaccharides, sucrose, lactose,
maltose
polysaccharide - Ans--starch, glycogen, cellulose
chains
cellulose - Ans--non digestible, main component of fiber
protein - Ans--keratin (hair scale feather), collagen (skin elasticity), muscle
fibers (contract relax), bones, enzymes
basic structure is amino acids
amino acids - Ans--contain a nitrogen containing group (amino) and a
carbon containing group, R's vary per acid, amino acid + amino acid =
peptide bond
protein structure - Ans--primary- contains both groups of the amino acids
, secondly- helix with a bunch of primary's
tertiary- bunch of secondary's contain heme which can hold up to 4 O
molecules, 1 heme per polypeptide, 4 polypeptides
lipids - Ans--fats and oils, butter, cream, nuts, egg yolk; long term energy
storage
triglycerides - Ans--saturated and unsaturated fat, type of lipid, formed from
glycerol and 3 fatty acids
saturated fat - Ans--carbon has only single bonds, solid at room
temperature, (meat)
unsaturated fat - Ans--carbon has double bonds, liquid at room
temperature, (plant)
cholesterol - Ans--type of lipid, in the steroid family
nucleic acid - Ans--dna (CGAT) and rna (CGAU), broken down into
nucleotides in digestion
nucleotides - Ans--phosphate, sugar, nitrogen bas; digestion uses
phosphate and sugar components
mouth (oral cavity) - Ans---incisors: cut food
-canines: tear/shred food
-molars: grind/crush food
mechanical form of digestion (voluntary)
mucus, water, saliva
saliva - Ans--lysozimes enzymes- destroy bacteria
amylase enzymes- digest polysaccharides
1st use of enzymes in the digestive process
bollus - Ans--food ball
parastulsis - Ans--involuntary, motion that pushes food down the
esophagus
