Matter & Energy
Anything that has mass and takes up space.
What is matter?
This subatomic particle has a positive charge.
What is a proton?
This subatomic particle is responsible for chemical bonding.
What are electrons?
This inorganic molecule accounts for more than two-thirds of the bodies weight.
What is water?
The most important carbohydrate used by body cells to create energy.
What is glucose?
The type of energy that is stored in the bonds of food and released when you chew and digest your food.
What is chemical energy?
The basic building block of matter.
What is an atom?
The valence shell of an atom can hold up to this many electrons (unless it is the only energy level).
What is 8?
NaCl is an example of this type of inorganic molecule, which are required by the human body as electrolytes.
What is salt?
These monomers are the building blocks of proteins.
What are amino acids?
This state of matter does not make up any components of the human body, but does circulate throughout it when exchanged with the environment.
What is gas?
In a particular electrically neutral atom of carbon, the electron number is 6. This is the number of protons.
What is six?
This charged molecule is formed when an atom gains or loses an electron.
What is an ion?
This kind of inorganic molecule has a low pH and is considered a proton donor.
What is an acid?
These chemical catalysts are specific type of protein that help reactions occur faster by lowering the amount of energy needed for them to occur.
What are enzymes?
Energy directly involved in moving matter such as when you pedal a bike.
What is mechanical energy?
These are formed when two or more different atoms are chemically joined together.
What are compounds?
This type of bond is created when electrons between two molecules are unequally shared due to a difference in electronegativity.
What is a polar covalent bond?
These chemicals are in the body and help to maintain pH level by taking up excess hydrogen or hydroxyl ions.
What are buffers?
This type of reaction is used to combine molecules such as when creating disaccharides or protein molecules by the removal of water.
What is a dehydration reaction?
This type of energy is used by the nervous system to create nerve impulses to transmit messages from one part of your body to another.
What is electrical energy?
Carbon has an atomic weight of 12.011, where as the mass number is 12. Sometimes, it can be found as Carbon-12 and sometimes it can be found as Carbon-14. These two molecules are considered isotopes, which result from a differing number of these.
What are neutrons?
This anabolic type of reaction occurs when two or more atoms or molecules combine to form a larger, more complex molecule.
What is a synthesis reaction?
This type of exchange reaction occurs when acids and bases are mixed and ultimately create water and a salt.
What is a neutralization reaction?
This lipid molecule is the most important steroid and plays are role in cell membrane fluidity.
What is cholesterol?
