Atoms
Particles that are found at the center of an atom with no charge.
neutrons
Macromolecule that stores genetic information?
nucleic acids
Water molecules are able to form droplets and are held together because of
Van der Waals
Macromolecules that are polymers are held together by this type of bond
covalent bond
The pH range that the body works to maintain for homeostasis.
6.5-7.5
The three subatomic particle of an atom.
protons, neutrons, & electrons
The 4 macromolecules.
lipids, proteins, carbohydrates, and nucleic acids
Bonds that are created through the sharing of electrons.
covalent bonds
Displays and groups elements based on similar chemical and physical properties.
Periodic Table
A type of protein that is a biological catalyst
enzyme
Positively charged particles found at the center of an atom.
Protons
Macromolecule that is a catalyst of biological reactions, provides structural support, and chemical signaling. This macromolecule is involved with most functions of the body and is a polymer.
protein
A homogenous mixture formed by dissolving a substance in a solvent.
solution
The subunits that make up polymers
monomers
Enzymes reduce this
activation energy
True or False: Elements with similar chemical properties are placed into groups on the periodic table.
True
Macromolecule that is responsible for helping form cell membranes, store energy, and chemical signaling. This macromolecule is NOT a polymer.
Lipid
Universal solvent, cohesion, and adhesion are all properties of
water
Two atoms of the same element that have the same number of protons, but differ in the number of neutrons.
Isotope
True or False: Enzyme activity is not influenced by pH levels.
False
Particles that have a negative charge, located in energy levels, and directly involved with bonding.
electrons
Macromolecule that is used for structural support, energy storage, and chemical signaling.
carbohydrates
A substance that releases hydroxide ions into solutions.
base
The 4 most abundant elements found in living things.
hydrogen, oxygen, nitrogen, carbon
This type of chemistry that studies carbon and it compounds.
