5481932986State of MatterWater- Liquid(rare) Gas- least dense that a liquid Solid - Densest1
5481939641Hydrogen Bonds (weak)holds together water molecules to each other (2 or more) Form quickly and Break Quickly2
5481945541Covalent Bonds (stronger)almost impossible to break3
5481950334Cohesionsame substance attraction H2O to H2O4
5481954006Surface TensionBugs walk over water5
5481957799Adhesion characteristicsdifferent substance attractions stronger than cohesion Example- water up a tree6
5481965313Heat capacity/ Specific heat characteristicsThermal Capacity ... energy in/out to change the temperature of substance. Related to numbers of hydrogen bonds. Small amount of hot coca takes awhile to heat up7
5481972240Lake Michigansummer-water is cold- air conditioning Fall-lake water warm - heat8
5481979192Carbohydrate characteristicsBread,grains,pasta,sugar,starch,fiber. Saccharides9
5481986441Simple Carbohydrate characteristicsQuick energy Milk refined sugar "pretty bad" "mono"10
5481990387Complex Carbohydrate characteristics"Poly" "big" Fiber11
5481993813Carbohydrate Functionmain source of energy makes up cell parts in both plants and animal cells12
5481996804Lipids characteristicsFats Glycerol and Fatty Acid13
5481999580Saturated Lipid characteristicssingle bond solid at room temperature "unhealthy in comparison" animal14
5482002058Unsaturated Lipid characteristicsdouble bond liquid at room temperature "healthier" plant15
5482005152Lipid functionstore energy and provide the waterproof coat to your cells16
5482008332ProteinAmino acids need food to make nine of them17
5482010601Protein Characteristicsamino acids- biochemicals- most important18
5482011369Protein function"building blocks"19
5482016067Organic Compound types ( Carbohydrate)"mono", "poly", and "di" saccarides Mono to mono- di - dehydration synthesis "di+mono = mono+mono (hydrolysis) can be... sugar/starches Smaller carbohydrate=smaller "mono" saccaride Complex carbohydrate=bigger "poly" saccaride20
5482018186Organic Compound types (lipids)examples- oils,wax,and butter21
5482018187Organic Compound types( protein)humans-20 amino acids R chain changes but everything else stays the same22
5482035191Enzyme-substrate complexCatalyst are protein based catalyst known as enzymes which bind to only one substrate. Enzymes work by lowering the activation energy needed to start a chemical reaction which begins with recants and combined to from a product or products23
5482041498EnzymesProteins- long chains of amino acids Needed to survive or food will not digest Work in either a neutral, acidic, or basic environment- only one contains an active site24
5482048890Factors that effect Enzymes (Temperature)Can increase or decrease effectiveness's humans-98.6 degrees Fahrenheit25
5482048891Factors that effect Enzymes (PH level)Thrive under certain conditions Acid- stomach Base- cleaners Neutral- water based26
5482048892Factors that effect Enzymes (Numbers)the more enzymes you have the faster the reactions27
5482049447Factors that effect Enzymes (Regulatory molecules)chemicals within a cell which can turn enzymes on or off28
5482061751PH level0-7 = Stronger acid 7-14 = Stronger base 7 = Neutral29
5482065350Small intestine (PH level)8 or 9 base related enzymes30
5482066003Buffersfound inside cells to stabilize the internal PH of a cell31
5482067411Water (PH level)neutral or 7 polar molecule32
5482069807Stomach acid (PH level)2 acid related enzymes33
5482072613Salivary Amylasestart to break down large poly-saccarides before it enters the mouth34
5482076332Lactasebreaks down diary di- sacarides to a mono-sacardies35
5482079576Cellulosebreaks down plant material humans lack this36

5482082084Typsinbreaks down proteins38
5482082595Lipasebreaks down lipids39
5482085108Peptidebreaks down to amino acids40
5482086508Digestion Step Oneingestion41
5482086509Digestion Step Twofood is broken down into pieces absorbed by our small intestines42
5482086908Digestion Step ThreeAbsorption- small intestines absorb nutrients into blood. Large intestines absorb water43
5482086909Digestion Step FourElimination- passes through the large intestines where any material not digested becomes "rough agel"44
5482097201Digestion Process in bodyMouth Esophagus stomach small intestines large intestines-colon rectum anus45
5482100161Mechanical Digestionmouth chews Esophagus and stomach muscles contract46
