chemical basis life


what are the organic substances carbonhydrates, lipids, proteins, nucleic acids
what are the uses in the body for carbohydrates immediate energy, shoot- term energy storage, cell structure
elements of carbohrdrates c,h,o
monomers of carbohydrates monosaccharides
examples of a monosaccharides fructose, glucose
examples of a disaccharides sucrose, lactose
examples of a polysaccharides starches, glycogen
lipose is what fat
elements in a lipid c,h,o,p
what are the three examples of lipids and their uses fats, energy storage...phospholipids, form cell membrane and other structures...steroids, form hormones, bile
fats,phospholipids,steroids what do they do energy storage...form cell membrane and other structures...form hormones, bile
what does a triglyceride monomers contain glycerol and 3 fatty acids
all single bonds b/w C atoms- fully filled with H is saturated
one or more double bonds b/w C atoms- spaces for more H unsaturated
what is a better energy source for the body carbs
elements in a protein c,h,o,n and sometimes s
uses in a protein in the body structures, hormones, enzymes, antibodies, energy
monomers of proteins amino acids
components of an amino acid amino acid, carboxyl group, side chain
how many diff amino acids exist 20
what creates the various diff proteins different R groups
3 dimenstional shape caused by different amino acids native conformation
shape changes or falls apart due to heating, beating, freezing, electricity,ph denaturation
elements in nucleic acids c,h,o,p,n
monomers of nucleic acids nucelotides
nucleotides are made up of sugar, phosphates, nitrogenous base
store info to make up proteins, pass on info to daughter cells?? functions of deoxyribonucleic
function of ribonucleic acid copy info to make proteins
synthesisrxns- building molecules anabolism
dehydration happens in what anabolism
as bond is formed h2o is released dehydration synthesis
breakdown molecules catabolism
consumes water in what catabolism
what is broken down to split a larger molecule hydrolysis
proteins that spend the rate of chemical reactions, they are biological catalysts enzymes
the molecule that a particular enzyme acts upon substrate
pockets on the enzyme where the substrate attaches active site
inorganic enzyme activator cofactor
organic enzyme activator coenzyme
a chemical from the enviroment needed by the body nutrient
body needs a large amount- carbs, lipids, proteins macronutrients
body needs small amounts- vitamins, minerals micronutrients
the amount of heat needed to raise the temputure of water, and cal or kcal = calorie, 1000cals
carbohydrates uses in the body immediate energy, short term energy storage, building some cell structures
broken into monosaccharides digestion
lipids uses in the body triglyceriods, phospholipids, steroids
kilocalories per gram in lipids = 9.3
essential fatty acids or what required for phospholipid synthesis also linolenic unoleic acid
kilocalories per gram in a protein 4.5
breaks down proteins into what amino acids
breaks triglycerides into what glycerol and 3 fatty acids
if inadequate glucose or fat is available, the liver converts amino acids into glucose and produces ATP through cellular respiration...the conversion requires what deamination producing NH3 waste
large organic molecules vitamins
vitamins can also be called coenzymes
there are two types of vitamins what are they fat soluble, and water soluble A,D,E,K and BS,C
small inorganic ions or compounds minerals
what are thease cooling, transport, waste removal, metabolism, shock absorber water uses in the body
rate of chemical reactions measured by heat produced metabolic rate
what are metabolic rate measured in kcals
rate in the body produces heat while at rest basal metabolic rate
in basal metabolic rate energy is used to what regulate body temp, breathing, heartbeat, anabolism
kilocalories per gram in a carbohydrates 3.7
