B3 + B4
B3
Proteins
Amino acids
Fats
saturated, unsaturated,
Carbohydrates
Glucose, galactose, fructose
Larger molecules are made from smaller molecules
Starch and Glycogen is made from glucose
Protein is from amino acids
Fats and oils from fatty acids and glycerol
Organic building blocks
Tests
Iodine solution = test starch
Results meaning
Benedict's solution = test sugars
Results meaning:
Biuret = proteins
Results meaning:
Ethanol emulsion test - fats and oils
Water is important as a solvent
helps cells transport and use substances like oxygen or nutrients
B4
Enzymes : proteins that function as biological catalysts
Enzymes speed up chem rxn by lowering activation energy
Not consumed by reaction
Enzyme shape:
Effects of changes in temperature on enzyme activity
Kinetic energy
Increase temperature, kinetic energy will increase
Shape and fit
Decrease temperature, shape and fit are unaffected but if you increase temperature, protein will denature
frequency of effective collisions
increase temperature, KE will increase, and frequency of collisions increase
Denaturation
Process in which protein loses its shape, generally irreversible and proteins cannot regain its shape
