1. Prokaryotic Cells - ANSWER ✔ Lack nuclear envelope
2. Eukaryotic Cells - ANSWER ✔ have nucleus
3. RNA World - ANSWER ✔ The idea that RNA was the initial genetic
system. Early stages of chemical evolution was thought to be based off of
chemical evolution
4. Genes - ANSWER ✔ the functional units of inheritance, corresponding to
segments of DNA that encode proteins of RNA molecules.
5. Transcription - ANSWER ✔ the nucleotides being copied into RNA. (DNA
is copied into mRNA by RNA polymerase)
6. Translation - ANSWER ✔ mRNA -> protein
7. phospholipids - ANSWER ✔ make up the membrane of the cell
,8. amphipathic - ANSWER ✔ one portion of the molecule is soluble in water
(hydrophilic) and the other end is not (hydrophobic)
9. ATP - ANSWER ✔ Source of metabolic energy
10.Glycolysis - ANSWER ✔ the breakdown of glucose into lactic acid yielding
2ATP
11.Active Site - ANSWER ✔ The region of an enzyme that binds substrates
and catalyzes an enzymatic reaction.
12.active transport - ANSWER ✔ the transport of molecules in an energetically
unfavorable direction across a membrane coupled to the hydrolysis of ATP
or other source of energy
13.Adenine - ANSWER ✔ a purine that base-pairs with either thymine or uracil
14.allosteric regulation - ANSWER ✔ The regulation of enzymes by small
molecules that bind to a site distinct from the active site, changing the
conformation and catalytic activity of the enzyme.
15.alpha helix - ANSWER ✔ a coiled secondary structure of a polypeptide
chain formed by hydrogen bonding between amino acids separated by four
residues
16.amino acids - ANSWER ✔ building blocks of proteins
,17.amphipathic - ANSWER ✔ A molecule that has both a hydrophilic region
and a hydrophobic region.
18.Beta barrel - ANSWER ✔ A transmembrane domain formed by the folding
of beta sheets into a barrel-like structure.
19.beta sheet - ANSWER ✔ A sheetlike secondary structure of a polypeptide
chain, formed by hydrogen bonding between amino acids located in different
regions of the polypeptide.
20.Carbohydrates - ANSWER ✔ a molecule with the formula CH2O
21.carrier proteins - ANSWER ✔ a protein that selectively binds and transports
small molecules across a membrane
22.cellulose - ANSWER ✔ principal structural component of the plant cell
wall, a linear polymer of glucose residues linked by Beta 1,4 glycosidic
bonds
23.channel proteins - ANSWER ✔ a protein that forms pores through a
membrane
24.RNA - ANSWER ✔ Believed to have been the original genetic system
because it can catalyze the polymerization of nucleotides into another RNA
strand.
, 25.Membrane-enclosing RNA molecules - ANSWER ✔ Initially important
because they maintained these molecules as a unit capable of reproduction
and evolution.
26.Stanley Miller's experiment - ANSWER ✔ Showed that under a reducing
atmosphere of methane, ammonia, water, and hydrogen, amino acids can
form.
27.First energy-producing process in cellular evolution - ANSWER ✔ Thought
to be glycolysis.
28.Earth's atmosphere at the time life arose - ANSWER ✔ Contained abundant
amounts of H2, N2, H2S, but not O2.
29.Organisms using H2O in photosynthesis - ANSWER ✔ Radically changed
Earth by producing O2.
30.Distinguishing feature of eukaryotes - ANSWER ✔ The presence of a
nucleus in eukaryotic cells.
31.Cytoplasmic organelles - ANSWER ✔ Absent in prokaryotic cells and
present in eukaryotic cells.
32.Eukaryotic nucleus - ANSWER ✔ Contains multiple linear DNA molecules.
33.Studying Molecules, Cells, and Organisms - ANSWER ✔ - bacteria is great
to study what prokaryotes do, and yeast is good for studying eukaryotes -
