Draw dehydration synthesis of a disaccharide

Boom

Draw hydrolysis of a disaccharide

Boom

Draw dehydration synthesis of a triglyceride

Boom

Draw hydrolysis of a triglyceride

Boom

Draw dehydration synthesis of a polypeptide

Boom

Draw hydrolysis of a polypeptide

Boom

Functional groups - hydrocarbons

Non polar —> required a lot of energy to break bonds, therefore makes good fuel

Add hydroxyl to a hydrocarbon

Becomes polar, lowering melting and boiling point

Functional group - hydroxyl (draw)

OH

Functional group - carboxyl (draw)

COOH

Functional group - amino (draw)

NH2

Catabolism

Larger molecule —> energy + smaller units. When bonds are broken energy is released

Anabolism

Energy + smaller units —> larger molecule. Uses energy to make bonds.

Dehydration synthesis

Remove/produce water —> make bigger molecules

Hydrolysis

Add water —> break apart molecules

Oxidation

LEO —> loss of electrons

Reducation

GER —> gaining electrons

Exergonic

Reactant releases energy (ex. cellular respiration) (draw)

Endergonic

Reactant gains/uses energy (eg. photosynthesis) (draw)
