Matter and Bonds | Water and Solutions (pH) | Carbon Compounds | Energy and Metabolism | Miscellaneous |
---|---|---|---|---|
What are atoms?
These particles are the smallest unit of matter that cannot be broken down by any chemical means.
|
What is cohesion?
100 PT EC: Which property of water is where it sticks to other things, like glass?
This property of water can be observed when water makes round droplets, essentially sticking to itself.
|
What is Carbon?
EC: What's special about Carbon?
This element is the basic unit of all biomolecules?
|
What is reactant?
EC: What's the term for what the result of a chemical reaction?
In a chemical reaction, this is the substance that is changed. It's like the ingredients in a recipe.
|
What is valence electrons?
These electrons are the ones that actually take part in bonding.
|
What are electrons?
These sub-atomic particle have a negative charge, and are the particle that take part in chemical bonds.
|
What is acidic?
EC: A solution with a pH of 4 will have how many more H+ compared to a solution with a pH of 7?
This type of solution is one that has many "free" H+ in the solution. It's pH is less than 7.
|
What is a carbohydrate?
EC: What's the monomer (basic unit) of carbohydrates?
This biomolecule is responsible for supplying immediate energy to the body and structural support,like the cell walls of plants/fungi and exoskeleton of insects.
|
What is the Law of Conservation of Mass?
EC: Which law states energy cannot be created nor destroyed, only transferred from one form to another?
This law states that matter cannot be created nor destroyed in a chemical reaction.
|
What is homeostasis?
This term means that organisms maintain a stable internal environment (like pH, and temperature).
|
What is a covalent bond?
EC: What does an ionic bond do with valence electrons? Provide and example.
This type of bond is formed when valence electrons are shared between atoms.
|
What is "less dense as a solid"?
EC: Without this property of water, the Earth's temperature would be much less stable.
This property of water is why ice floats...perfect for ice tea.
|
What is a lipid?
EC: What's the term for a lipid that functions as a hormone?
This biomolecule acts to store long-term energy in the body, forms a water barrier, and can act as a chemical signal in the body (hormone).
|
What is an enzyme?
This protein molecule works to speed up chemical reactions by lowering the activation energy and aligning molecules just right.
|
What are substrates?
|
What are gluons?
These sub-atomic particles are responsible for holding multiple quarks together, which work to form protons and neutrons.
|
What is "almost all of our chemical reactions need to live occur in solutions"?
EC: Why is the pH of these solutions important?
Why are solutions important for living organisms?
|
What is a protein?
EC: What's the monomer of a protein?
This biomolecule functions to allow movement of the body, transport materials (like oxygen) in the body, and as an enzyme.
|
What is "meet the minimum activation energy", and "the atoms are aligned correctly".
[Activation Energy and Alignment]
In order for a chemical reaction to take place, these two conditions must be met.
Hint: think about what enzymes do. |
What is active site?
|
What are mesons?
These sub-atomic particles are responsible for holding neutrons and protons together.
|
What are hydrogen bonds?
EC: What about water molecules allows them to hydrogen bond?
These bonds are the whole reason why water has all its unique properties.
|
What is nucleic acids?
EC: What is the energy carrying molecule in organisms? Hint: it's a nucleotide with 2 extra phosphates.
Which biomolecule functions to store genetic information?
|
What is metabolism?
This is the term for all of the chemical reactions in the body.
|
What are proteins?
500 EC: What type of bond is unique to proteins?
Enzymes are this type of macromolecule, which also functions as antibodies, to transport oxygen, to move muscles, and as structural components in your skin and hair among many other functions.
