Matter Monday
This positively charged subatomic particle is found in the nucleus and determines an element’s identity.
What is a proton?
This type of bond occurs when two atoms share electrons.
What is a covalent bond?
This level of structure is defined by the amino acid sequence of the protein.
What is the primary structure?
This type of nucleic acid is single stranded and conveys information out of the nucleus to the ribosome.
What is RNA?
Cellular membranes are made of a bilayer of this kind of amphipathic molecule.
What is a phospholipid?
This structure around the nucleus of an atom can fit up to two electrons.
What is a shell or s orbital?
This type of bond forms between hydrogen and an oxygen or nitrogen atom.
What is a hydrogen bond?
Mammalian proteins consist of twenty amino acids, distinguished from each other by this group.
What is the R group?
This nucleotide is only found in DNA.
What is thymine?
This type of fatty acid contains only single bonds in its carbohydrate chain, allowing it to form solid complexes at room temperature.
What is a saturated fat?
This structure around the nucleus of an atom is not present in hydrogen or helium, and can hold up to six electrons.
What is a p orbital?
Ionization occurs when a molecule formed by ionic bonds is dissolved in this kind of solvent.
What is a polar solvent?
What is the secondary structure?
These two nucleic acids have two rings and are known as purines.
What are adenine and guanine?
Monosaccharides have this three letter suffix.
What is “-ose”?
A solution with a pH of 6 has this many more times hydrogen ions than a solution with a pH of 7.
What is 10X?
This type of weak bond is formed between polar molecules.
What are van der Waals forces?
This describes a protein whose functional, three-dimensional form has been disrupted by heat, acid, alcohol, or other chemicals.
What is denatured?
The removal of the third phosphate of this molecule releases energy that can be harnessed to do work in a cell.
What is ATP?
This molecule binds to fatty acid chains and a phosphate group in a phospholipid.
What is glycerol?
This unit is equal to 6.022x1023 and is used in the laboratory to convert between molecules and grams.
What is a mole?
This type of covalent bond is formed when two electrons come from one atom, and is common in bonds with metals.
What is a coordinate covalent or dative bond?
This type of bond between cysteine groups helps stabilize the protein's tertiary structure.
What are disulfide bonds?
This base pair has three hydrogen bonds holding it together.
What is G-C?
This molecule is found in the outer membrane of gram-negative bacteria and can cause fever and shock in humans.
What is lipopolysaccharide?
