Matter & Atoms
Atomic mass is determined by adding what two things together
What are protons and neutrons
This type of bond is formed when atoms share electrons
What is a covalent bond
What type of reaction combines smaller molecules into larger ones?
What is a synthesis reaction
What is the pH range of a healthy human adult?
What is 7.35 to 7.45
What are the building blocks of proteins?
What are Amino acids
These give an atom their identity
What is a proton
What type of bond is the strongest?
Ionic bonds
These special proteins speed up chemical reactions without being used up
What is an enzyme
What roles does water play in physiology?
These organic molecules provide the body's main energy source
What are carbohydrates
This term describes an atom with an unequal number of protons and electrons
What is an Ion
What determines the type of bond that will form?
What is electronegativity
The minimum amount of energy needed to start a chemical reaction
What is activation energy
What is the difference between solution, colloid, and suspension
Solution = small particles evenly dissolved
colloid= medium particles that are dispersed
suspension= large particles not evenly distributed
These organic molecules act as enzymes, hormones, and structural molecules
What are proteins
The outermost shell of electrons that determine its chemical behavior and reactivity
what is a valence shell
This type of bond is responsible for DNA base pairing
This type of energy is stored in the bonds of molecules
What is potential energy
Salts are essential for maintaining what in the human body?
What is fluid balance, pH, and overall homeostasis
These molecules store and transmit genetic information
What are nucleic acids

What are isotopes
What is formed when an atom gives an electron to another atom? what is the one that received the atom called?
What is a cation and an anion
what is the name of the energy molecule needed for most cellular processes in your body?
What is ATP
What is the importance of acids and bases in the body?
help maintain enzyme function, support chemical reactions, and contribute to overall homeostasis
