Atoms & Bonds
This negatively charged subatomic particle is found outside the nucleus.
What is an electron?
Water sticking to other water molecules demonstrates this property.
This macromolecule is generally the quickest source of usable energy.
What is carbohydrate?
These macromlecules are the major source of long term energy storage.
What are lipids?
These monomers join together to form proteins.
What are amino acids?
These are the monomers that build nucleic acids.
What are nucleotides?
An atom that gains or loses electrons becomes this charged particle.
What is an ion?
Water climbing up a narrow tube because it sticks to another surface demonstrates this property.
What is adhesion?
Glucose and fructose belong to this group of simple carbohydrate monomers.
What are monosaccharides?
Lipids provide this many calories per gram.
What is 9 calories per gram?
This type of bond joins one amino acid to another.
What is a peptide bond?
A nucleotide contains a phosphate, a nitrogenous base, and this type of sugar.
What is a 5 carbon sugar?
This bond forms when atoms share electrons.
What is a covalent bond?
Oil refuses to mix with water. Oil is described by this water fearing term.
What is hydrophobic?
Plants store excess glucose primarily in this polysaccharide.
This special lipid is a major component of the cell membrane.
What is a phospholipid?
A long chain of amino acids is called this.
What is a polypeptide?
DNR and RNA belong to this macromolecule group.
What are nucleic acids?
This weak attraction forms between the slightly positive hydrogen of one water molecule and a slightly negative region of another.
What is a hydrogen bond?
Water resists rapid temperature changes because it has this property.
What is high specific heat?
Animals store glucose primarily in this polysaccharide.
What is glycogen?
The phosphate head of a phospholipid has this relationship with water.
What is hydrophilic, or water loving?
Antibodies belong to this macromolecule group.
What are proteins?
This reaction builds a polymer by joining monomers while removing water.
Carbon is especially useful in biological molecules because it can form this many covalent bonds.
What is four?
A pond freezes on top while fish survive below because frozen water has this relationship to liquid water.
What is that ice is less dense than liquid water.
This carbohydrate polymer provides structural support in plant cell walls.
What is cellulose?
The fatty acid tails of a phospholipid have this relationship with water.
What is hydrophobic, or water fearing?
A protein loses its normal three-dimensional shape after exposure to extreme heat. This process is called this.
What is denaturation?
This reaction uses water to split a polymer into smaller units or monomers.
What is hydrolysis?
