Why is carbon such a versatile element?
Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
What are the other three elements that carbon most frequently bond with?
Hydrogen, Oxygen, and Nitrogen
In what ways can carbon skeleton vary?
length, branching, double bond position, and presence of rings
What is a functional group?
A group of atoms in a molecule that determines how that molecule typically reacts
What is a peptide bond?
A covalent bond formed when the carboxyl group of one molecule reacts with an amino group of a different molecule
When cells link monomers together to construct polymers, which process is used to make the monomers form bonds with each other?
DNA and RNA are classified as
Antibodies and hemoglobin are classified as
Cholesterol and testosterone are classified as
Glucose and Glycogen are classified as
What process is used to break down polymers into monomer?
What are some examples of disaccharide?
sucrose, lactose, maltose
What are some examples of carbohydrates?
Cellulose, Glucose, Sucrose, Fructose, Starches.
What are some monomers, or building blocks, of nucleic acids?
What are some examples of monosaccharides?
glucose, fructose, galactose
Both DNA and RNA are made up of building blocks known as
What are traits of DNA that differs from RNA?
RNA uses uracil and DNA uses thymine. RNA is single stranded is double stranded
Are cellulose linear chains unbranched, moderately branched, or highly branched?
Are glycogen linear chains unbranched, moderately branched, or highly branched?
Are starch linear chains unbranched, moderately branched, or highly branched?
What are polymers?
molecules composed of smaller sub units linked together
What are monomers?
single molecules that can be linked together to form larger molecules
What are some examples of monomers?
amino acids and simple sugars
What are some examples of Polymers?
muscle protein, starch, and RNA.
How does a dehydration reaction differ from a hydrolysis reaction? (2 ways it does this)
1).A water molecule is removed during dehydration and added in hydrolysis. 2). Polymers break into monomers in hydrolysis and monomers join together in dehydration
