Nature of matter
What are the 3 subatomic particles
What is a proton, neutron and electron
Name one of the 2 types of weak bonds
What are Vander Walls forces or H bonds
Name the 4 macromolecules
What are carbohydrates, lipids, proteins and nucleic acids?
Enzymes are mostly made from this macromolecule
What are proteins.
Water and oil do not mix. Water is a polar molecule while oil is this.
What is non=polar?
List the charges of the 3 subatomic particles
What is proton- positive, neutron- neutral, electron- negative
These bonds create charged elements because they give or take electrons
Ionic bonds
The building blocks of starches (carbohydrates)
What are simple sugars (glucose, monosaccharides)
Enzymes make reactions go faster by doing this?
What is lowering the activation energy?
Water makes droplets/sticks to itself because of this property
What is cohesion?
These particles are in constant motion around the nucleus
What are electrons
THese bonds share electrons
Covalent bonds
the building blocks of proteins
What are amino acids
When a proteins shape is changed, I'd will not work. This is called what.
What is denatured
These bonds hold molecules of water together and are responsible for surface tension
What are H bonds
An element has a specific number of protons. When the number of electrons are different you get this.
What is an ion
NaCl is help together by this type of bond
What is ionic
Amino acids differ from each other by this
What is the R-group
These cause proteins to denature
What are temperature and pH
On the pH scale, bases are what number
What is 7.1 to 14
different forms of the same chemical element that have the same number of protons but a different number of neutrons
What is an isotope?
The elements of water are held together by covalent bonds, but electrons are unequally shared, this is called...
What is Polar (polarity)
This macromolcule is responsible for genetic material
What is a nucleic acid?
Latose is milk sugar. If a person is lactose intolerant they do not have this enzyme
What is lactase
These basic chemicals keep additional acids or bases from changing the pH of a substance
What are buffers?
