Atoms - ✔️✔️Building blocks of elements, smallest units of matter
Atomic number - ✔️✔️# of protons in the nucleus
Mass number - ✔️✔️Protons + Neutrons
Isotopes - ✔️✔️Atoms with the same number of protons but different number of
neutrons
Compounds - ✔️✔️Formed when electrons are exchanged between atoms
Molecule - ✔️✔️composed of two or more atoms that share electrons
Ion - ✔️✔️An atom has a positive or negative charge
Ionic Bond - ✔️✔️Atoms donates or accepts electrons from interacting atoms to create
a stable valence shell
Cation - ✔️✔️Positively charged ion
Anion - ✔️✔️Negatively charged ion
Covalent bond - ✔️✔️sharing of electrons either equally or unequally
Nonpolar - ✔️✔️Equally Shared
Polar - ✔️✔️Unequally shared
Hydrogen bonds - ✔️✔️Weakened bond
Put and ionic bond in a solution _________ - ✔️✔️it becomes weaker
Reactants - ✔️✔️atoms in the reacting substances
Products - ✔️✔️results
Metabolism - ✔️✔️all the actions being performed in your body
Work - ✔️✔️Movement of an object or change in physical structure
, Energy - ✔️✔️capacity to perform work
Kinetic - ✔️✔️Energy of motion
Potential energy - ✔️✔️stored energy
Cellular work includes - ✔️✔️-producing complex molecules
-Moving material into in out of a cell

Skeletal muscle cells are an example of what type of energy? - ✔️✔️Potential energy
Contraction - ✔️✔️turns potential to kinetic
Byproduct of Contraction - ✔️✔️Heat
Metabolic Pathway - ✔️✔️Series of complex reactions where the product is the
reactant for another reaction
Decomposition - ✔️✔️Reaction that breaks a molecule into smaller fragments
Hydrolysis- - ✔️✔️Take a compound, combined with water, and it splits a large
compound.
Catabolism - ✔️✔️Taking big and complex components and breaking them down into
their smaller components
Synthesis - ✔️✔️Take two individual pieces and throughout the process to form a
compound
Dehydration synthesis - ✔️✔️Formation of a complex molecule by removing a water
molecule
Anabolism - ✔️✔️Taking smaller components and combining them to make them
bigger and more complex
