What do you know? True or False Thumbs up for TRUE Thumbs down for FALSE Sugar is a carbohydrate. TRUE

What do you know? True or False Thumbs up for TRUE Thumbs down for FALSE Protein stores energy. FALSE

What do you know? True or False Thumbs up for TRUE Thumbs down for FALSE Hydrolysis is when monomers bond to form a polymer. FALSE

What do you know? True or False Thumbs up for TRUE Thumbs down for FALSE Lipids store more energy than carbohydrates. TRUE

What do you know? True or False Thumbs up for TRUE Thumbs down for FALSE Amino acids store genetic information. FALSE

Macromolecules Review Enzymes – Lower activation energy (energy needed to start a chemical reaction). – Enzymes bind to molecules that are involved in reaction. – Enzymes release products and are ready for the next reaction.

Denatured When an enzyme changes shape. Due to pH and temperature changes.

Dehydration Synthesis (Condensation Rxn.) Monomer + monomer  polymer + H 2 O

Hydrolysis Polymer + H 2 O  monomer + monomer

Nucleic Acid DNA or RNA Base + phosphate + sugar Store genetic info Help make proteins Monomer = triglyceride

Protein Structure, hormones, antibodies… Monomers are amino acids. Amine group (NH 2 ) + carbon group + carboxyl group

Carbohydrate Monomers are simple sugars (monosaccharide). Starches in animals = glycogen, plants = cellulose.

Lipids Store long-term energy Steroids Cell membrane Glycerol Where we get Triglyceride (the monomer)
