Atoms
This subatomic particle has a negative charge and orbits the nucleus.
What is an electron?
This is the body's primary and quickest source of energy. (Hint: Don't overthink it)
What are carbohydrates?
This type of biomolecule includes fats, oils, and waxes and is hydrophobic.(Hint: Don't overthink it)
What are lipids?
These are the building blocks of proteins.
What are amino acids?
DNA and RNA are examples of this type of biomolecule.
What are nucleic acids?
The center of an atom contains these two types of particles.
What are protons and neutrons?
The simplest form of carbohydrates, like glucose and fructose, are called this.
What are monosaccharides (or simple sugars)?
The building blocks of most lipids are these two molecules.
What are glycerol and fatty acids?
This type of bond links amino acids together in a protein chain.
What is a peptide bond?
The three components that make up a nucleotide are a sugar, a phosphate group, and this.
What is a nitrogenous base?
This number tells you how many protons are in an atom's nucleus and defines the element.
When two monosaccharides bond together, they form this type of sugar.
What is a disaccharide?
Lipids are characterized by being insoluble in this common substance.
What is water?
Unlike carbohydrates and lipids, proteins contain this essential element in addition to carbon, hydrogen, and oxygen.
What is nitrogen?
DNA contains these four nitrogenous bases.
What are adenine (A), thymine (T), guanine (G), and cytosine (C)?
Atoms of the same element (same number of protons) with different numbers of neutrons are called this.
What are isotopes?
This polysaccharide provides structural support in plant cell walls and cannot be digested by humans.
What is cellulose?
The cell membrane is primarily made of this type of lipid with a hydrophilic head and hydrophobic tails.
There are this many different amino acids that can be combined to make all the proteins in the human body.
What is 20?
This five-carbon sugar is found in RNA but not in DNA.
What is ribose?
Atoms bond together to form these, which are the smallest unit of a compound that retains its chemical properties.
What are molecules?
This element, along with hydrogen and oxygen, is found in all carbohydrates in a 1:2:1 ratio.
What is carbon?
Triglycerides store more than twice as much energy per gram as carbohydrates, making them the body's most efficient form of this.
What is energy storage (or long-term energy)?
The unique sequence of amino acids in a protein is called this level of protein structure.
What is the primary structure?
What nitrogenous base in DNA is replaced by uracil in RNA?
What is thymine?
