A chemical bond that forms between 2 water molecules

What is a hydrogen bond?
100

What element is the building block for all organic molecules?  It is versatile because of it's ability to form 4 covalent bonds at a time.

What is Carbon?

100
A term for a single unit or building block of a biomolecule (macromolecule).

What is a monomer?

100

This biomolecule is the primary source of energy for living organisms.  

What are carbohydrates?

100

This is the sugar found in a DNA nucleotide.

What is deoxyribose?

200

A chemical bond that forms between the oxygen and hydrogens within one water molecule. 

What is a covalent bond?

200

These three elements are found in all biomolecules (macromolecules). 

What are Carbon, Hydrogen, and Oxygen?

200

A monomer of proteins, they consist of an an amino (NH2) end and a carboxyl (COOH) end.

What are amino acids.

200

This biomolecule serves as a back up energy source for animals.  It also serves to form membranes and insulation.

What are lipids?

200

These three molecules united make up a single nucleotide.

What are phosphate, sugar, and nitrogen base?

300

A term for two or more water molecules connected by a hydrogen bond.  This property is responsible for many other properties of water such as surface tension.

What is cohesion?
300

A term for a double layer of phospholipids.

Phospholipid Bilayer

300

A term meaning two monomers are separated by a water molecule breaking the covalent bond between them.

What is hydrolysis?

300

This biomolecule is the only one that does not serve to provide regular source of energy for the body.  It does make up many cell structures and aid in cell communication.

What are proteins?

300

This type of bond connects the phosphate group to the 5 carbon sugar, and the 5 carbon sugar to the nitrogen bases.

What are covalent bonds?

400

A term for a water molecule that attaches to another charged or hydrophilic molecule via hydrogen bond.

What is adhesion?

400

Of the biomolecules (macromolecules) this element is found only in proteins and nucleic acids.  It makes up the rungs on a DNA latter.

What is nitrogen?

400

A term meaning that two molecules are joined together via the removal of a water molecule to form a covalent bond.

What is dehydration synthesis? 

400

This biomolecule serves as a usable source of cell energy.  It is produced from breaking down carbohydrates.

What is ATP? or What are nucleic acids?

400

Nitrogen bases Adenine and Guanine that have double ringed structures.

What are purines?

500

This property of water is responsible for the formation of hydrogen bonds forming between water molecules and other charged particles.

What is polarity?

500

Of the four biomolecules (macromolecules) this element is normally found only in nucleic acids. On occasion it can be found in lipids.

What is phosphorous? 

500

A sugar molecule with branching chains that is difficult to break down. It is most often found in the muscles of animal tissue.

What is Glycogen?

500

This word refers to the breaking of chemical bonds within a formed protein resulting in the inability to perform expected functions.

What is denatured?

500

The chemical bond that connects nitrogen bases in the center of the DNA helix (unites purines with pyrimidines)
