What allows an insect to walk on water?
Surface Tension
100
Which macromolecule contains Phosphorus?
Nucleic Acid
100
What elements do ALL macromolecules have?
C, H, and O.
100
Enzymes speed up reactions. This makes them a(n) ____________.
Biological Catalyst
100
Which one can you associate with DNA and RNA?
#4 (Nucleic Acid)
200
Define cohesion and adhesion.
Cohesion - water sticking to water
Adhesion - water sticking to another surface
200
What is the purpose of lipids/fats?
Insulation, long-term energy storage, cell membrane
200
What is the MONOMER of nucleic acids?
Nucleotide
200
We know enzymes break down things? If lactase is breaking down lactose, what macromolecule would we classify lactose as?
Carbohydrate (remember, -ose means it's a sugar! Carbs are made up of saccharides/simple sugars).
200
What are the bonds that hold proteins together?
Peptide bonds
300
What is the property of water that allows it to dissolve other substances? (Ex: Water can dissolve salt)
Universal Solvent
300
What type of saccharide is this?
Disaccharide (two rings)
300
What is the monomer/building block of proteins?
Amino acids
300
What is it called when an enzyme changes shape? What causes this?
Denaturing, high and low pH and temperature.
300
Where is the catalyst?
Y (The enzyme). How do we know this is the enzyme?
400
What is capillary action and what 2 properties of water can we associate with it?
Movement of water against the force of gravity (ex: water moving from roots to stem/leaves in a flower). We are seeing cohesion and adhesion.
400
What is the monomer of a lipid?
Glycerol backbone and 3 fatty acid tails.
400
What is the function of carbohydrates?
Energy storage (fast energy)
400
Which of these can act as a biological catalyst?
#2 (Protein)
400
Why are enzymes different shapes?
They all have a different active site. Their shape allows them to have a specific substrate bind to them.
500
What property of water allows water to be an universal solvent?
Polarity (negative and positive charges)
500
What are the three parts of a nucleotide?
Nitrogenous base, sugar, and phosphate.
500
What elements does each macromolecule have?
Carbs?
Lipids?
Proteins?
Nucleic Acids?
Carbohydrates - CHO
Lipids/Fats - CHO
Proteins - CHON
Nucleic Acids - CHONP
500
Enzymes speed up reactions by lowering the ______________ ____________. Also define what the blank is.
Activation energy - the amount of energy needed to start a reaction.
500
Which one can be a sugar?
#1 (carbohydrate)
