Macromolecules Part 2
Chemical Reactions & Enzymes
100
a molecule that has a positive end and a negative end; aka unequal chargers
polar
100
water has a pH of 7, so it is considered
neutral
100
large biomolecules (proteins, lipids, Carbs, & nucleic acids) are also called
macromolecules
100
This macromolecule is passed from generation to generation and codes for genes
nucleic acids
100
Enzymes are this type of macromolecule
protein
200
Property of water where water hydrogen bonds/is attracted to other water molecules
Bonus 100 is you give me an example of cohesion
cohesion
200
This substance has a pH below 7 and a high concentration of H+ ions
acid
200
the building blocks/subunits of macromolecules
monomers
200
This macromolecule can be saturated ir unsaturated
lipids
200
An enzyme is considered a catalyst because it
speeds up chemical reactions and/or lowers the activation energy
300
Property of water by which water sticks to other substances
adhesion
300
This substance has a pH above 7 and releases OH- ions
Base
300
repeating chains of monomers form
polymers
300
This macromolecule is a quick energy source used in the body
carbohydrate
300
Draw an enzyme substrate complex on the board
(label the active site, enzyme, and substrate)
teacher checked
400
Waters ability to move up a thin tube
capillary action
400
Explain why water and oil do not mix
water is polar and oil is nonpolar
400
Name the monomers of proteins and carbohydrates
proteins: amino acids
Carbs: monosaccharides
400
This macromolecule is joined together by peptide bonds and contains the elements CHON
proteins
400
What is the optimal pH of Gastric Protease
3
500
Identify what time of bond is represented by 6 and 7 (no I did not label it this way on purpose, chill)
6. Covalent Bond
7. Hydrogen Bond
500
Due to it's polarity water is great at dissolving solutes. It is said to be the universal
solvent
500
Name the monomers of nucleic acids and lipids
NA: nucleotides
Lipids: glycerol and 3 fatty acids
500
the ratio of this macromolecule (C:H:O) is 1:2:1
carbohydrates
500
An enzymes shape determines its function. When it loses its shape it is said to be
denatured
600
Why does ice float?
Please mention something about bonds
When water freezes hydrogen bonds space out and expand causing ice to become less dense then water
600
Stomach acid has a pH of 1. How many times more acidic is it than tomato juice, which has a pH of 4
1000
600
examples of this macromolecule include myosin, keratin, hormones, and antibodies
proteins
600
ATP is an energy source in living organisms. It is considered a special
nucleotide
600
