They can be single, double, or triple
They can bind together to make new elements. - 6What is a polymer?Water being removed from one molecule to create a larger one.
- 7What is polymerization?Monomers joining together to form a polymer.
- 8What are the 3 functional groups?Carboxyl (COOH)
Hydroxyl (-OH)
Amino group (NH2) - 9What's in a carbohydrate?Carbon
Hydrogen
Oxygen - 10What is a polysaccharide?Multi-chained polymers.
- 11What is glycogen?Simple sugars stored in a polysaccharide.
- 12What is cellulose?A building block for cell walls of plants.
It's a complex-carbohydrate for plants. - 13What is Fructose?cyclic glucose rearranged
Penta-sugar - 14What is Sucrose?Glucose+Fructose
- 15What is maltose?Glucose+Glucose
- 16What is a Lipid?Carbon
Hydrogen
Oxygen
BUT is INSOLUBLE in WATER - 17What is a Triglyceride?A glycerol head joined with 3 fatty acid chains.
Long time energy storage. - 18What is a Saturated Fat?A fatty acid chain of carbon atoms joined by single covalent bonds
- 19What is Unsaturated Fat?A fatty acid chain of carbon atoms joined by DOUBLE bonds.
- 20What is a characteristic of Saturated fat?Solid at room temperature
Has a rigid barrier
Is not permeable - 21What is a characteristic of a Unsaturated fat?Oily not solid
Selective barrier can let water/ other solutions through. - 22What is a protein?A large polymer(s) that aid in movement and structural support.
- 23What is an Enzyme?Proteins that increase the rate of a chemical reaction.
- 24Describe Amino Acids:Contain a Carboxyl (COOH) group and Amino group(NH2)
- 25How many types of amino acids are there?20
- 26What is a peptide?When two amino acids are joined together through dehydration
- 27What is a polypeptide?Multiple peptides linked together as a chain.
- 28What is a Nucleic Acid?Polymers made of :
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphorus - 29What are Nucleotides?Monomers that form the links of a nucleic acid chain.
- 30What are the 3 parts of a Nucleotide?Penta-sugar
phosphate group (sugar)
Nitrogenous base - 31What are Purines?Adenine & Guanine
- 32What are Pyrimidines?Cytosine & Thymine
- 33What are the 4 nucleotides?Adenine
Thymine
guanine
Cytosine - 34What is DNA?DeoxyriboNucleicAcid
Double helix - 35What is RNA?RiboNucleicAcid
Single strand - 36What is ATP?Adenosine TriphosPhate
- 37What is ADP?Aenosine DiphosPhate
- 38What is the difference between ATP & ADP?ATP: Unstable bond, consist of 3 phosphates bonded together.
ADP: Stable bond, releases energy, aids in cell activities. - 39What is the Empirical formula for Glucose?C6-H12-O6
- 40What is the empirical formula for Fructose?C6-H12-O6

- 42What is the empirical formula for Maltose?C12-H22-O11
- 43What is an Isomer?Molecules that share the same empirical formula but have different shapes.
- 44What are some examples of Isomers?1.) Glucose and Fructose
2.) Sucrose,Maltose and Lactose
