What are the base building blocks of macromolecules called?
Monomers
What do enzymes reduce?
activation energy (needed for a chemical reaction)
The sub-atomic particle that occupies the space outside of the nucleus called the energy levels.
electrons
This property of water is the reason that the ocean stays cold during the spring.
resists temperature change (able to absorb a large amount of heat energy)
Has a high concentration of H+ ions.
Acids
The macromolecules that store genetic information.
Nucleic Acids
The molecules that connect to the active site of the enzyme are called
substrates
When an electron is transferred from one atom to another atom, what kind of bond is formed?
Ionic Bond
The uneven distribution of charge causes water molecules to be this.
Polar

This macromolecule contains Nitrogen and Phosphorous.
Nucleic Acids
What type of macromolecules are enzymes?
Proteins
Atoms of the same element that have a different number of neutrons are called
Isotopes
Water molecules being attracted to water molecules is
cohesion
The substance being dissolved in a liquid is called the
solute
This macromolecule is responsible for forming bones, cell processes, and transport materials around the body.
Proteins
