after water what is the most abundant molecule in the cell? | proteins |
what are polymers made up of amino acids? | proteins |
define primary structure | sequence of amino acids in a protein |
define secondary structure | specific shape the long chain of amino acids assumes because of hydrogen bonds and other interactions between atoms |

Beta Alpha Beta motifs or BAB motifs are often involved with the binding of? | DNA |
define domain | functional unit within the tertiary and primary structures of large proteins |
define chaperones | proteins that help newly formed proteins fold into their correct secondary structures |
define denaturation and example | irreversible change of shape of a protein ex excessive heat low ph or high ph |
define renaturation | refolding protein back to proper shape |
why do proteins unfold | because of a disruption of the weak forces holding it in shape |
what makes up a nucleotide? | a hydrophilic phosphate group, a hydrophilic sugar and a nitrogenous base |
what makes up DNA ? | phosphate group a sugar and a base |
bases of DNA | A-G-C-T |
bases of RNA | A-G-C-U |

A= | adenine |
G= | glamine |
C= | cytosine |
T= | thymine |
U= | Urasil |
what does DNA replication use in prime? | goes from 5 prime to 3 prime |
hydrogen bonds always have the pattern | A-T G-C |
what is the difference between DNA and RNA | DNA has ATCG double helix and deoxyribose phosphate backbone RNA has AUCG single strand and ribose phosphate backbone |
what does A.T.P stand for? | adenosine triphosphate |
Define adenosine triphosphate (ATP) | a molecule that transfers energy from place to place in the cell |
define lipids | generally hydrophobic they have lots of carbon to hydrogen bonds that can produce energy |

what are all living things made of? | a double layer of phospholipids (cell membranes) |
define cells | everything a living thing is made up of and does is because of cells |
what is the cell theory | all living things are made of cells and cell products cells are the basic structural and function units of living things and ALL CELLS come from preexisting cells |
