1st law of thermodynamics - CORRECT ANSWER: matter can not be created note

destroyed, matter/energy can be transformed

2nd law of thermodynamics - CORRECT ANSWER: every transformation increases

entropy, in all energy transformation usable energy is lost as heat

a site - CORRECT ANSWER: tRNA enters and binds to ribosomes

acid - CORRECT ANSWER: A substance that increases the hydrogen ion concentration of a solution.

actin filaments - CORRECT ANSWER: smallest. microfilaments, long, thin fibers. cell migration and endocytosis. dynamic instability

activation energy - CORRECT ANSWER: initial input of energy to start reaction, brings molecules close together to cause bond rearrangement

active transport - CORRECT ANSWER: uses energy to move molecules from a low

concentration to a higher concentration (pump)

aerobic respiration - CORRECT ANSWER: requires oxygen, bacteria-cytoplasm,

eukaryotes-mitochondria

• / 4

alpha helix - CORRECT ANSWER: A spiral shape constituting one form of the

secondary structure of proteins, arising from a specific hydrogen-bonding structure.coiled structure

alternative splicing - CORRECT ANSWER: one gene can make several products

amino acid - CORRECT ANSWER: Building blocks of protein (monomer)

amphipathic - CORRECT ANSWER: A molecule that has both a hydrophilic region and

a hydrophobic region.

anabolism - CORRECT ANSWER: Building up of molecules. dehydration

anaerobic respiration - CORRECT ANSWER: does not require oxygen, found in all cells, occurs in cytoplasm for eukaryotes and prokaryotes

anaphase - CORRECT ANSWER: sister chromosomes pulled opposite poles

anaphase 1 - CORRECT ANSWER: (Step) Spindle fibers pull each homologous

chromosome pair toward opposite ends of the cell

anaphase 2 - CORRECT ANSWER: Centromere divides; sister chromatids separate;

happens in two cells at once

anion - CORRECT ANSWER: A negatively charged ion

anti porter - CORRECT ANSWER: move 2 molecules in opposite directions

• / 4

antioxidants - CORRECT ANSWER: neutralize free radicals, donate electron to free radicals without becoming unstable

apoenzyme - CORRECT ANSWER: protein part

apoptpsis - CORRECT ANSWER: cell death. damage triggers a cascade of events in

which cell '"commits suicide". prevents webbed fingers and toes

atomic mass - CORRECT ANSWER: Number of protons and neutrons

atomic number - CORRECT ANSWER: Number of protons in an atom

atoms - CORRECT ANSWER: elements are composed of

ATP - CORRECT ANSWER: energy currency of cell

ATP synthase - CORRECT ANSWER: uses energy from H+ gradient to make ATP

AUG - CORRECT ANSWER: start codon, methonine

autophagy - CORRECT ANSWER: self eating

autosomes - CORRECT ANSWER: Any chromosome that is not a sex chromosome

autotrophs - CORRECT ANSWER: plants and other organisms that make their own food

base - CORRECT ANSWER: A substance that decreases the hydrogen ion

concentration in a solution. 3 / 4

base pairs - CORRECT ANSWER: Any of the pairs formed between complimentary

bases in the two nucleotide chains of DNA, such as A-T and C-G (DNA) A-U and C-G (RNA)

beta sheet - CORRECT ANSWER: One form of the secondary structure of proteins in

which the polypeptide chain folds back and forth, or where two regions of the chain lie parallel to each other and are held together by hydrogen bonds. pleated structure

biomolecules - CORRECT ANSWER: Carbohydrates, lipids, proteins, nucleic acids

buffer - CORRECT ANSWER: A solution that minimizes changes in pH when

extraneous acids or bases are added to the solution.

calvin cycle - CORRECT ANSWER: occurs in stroma, uses ATP and NADH to "fix" CO2 in carbs

capping - CORRECT ANSWER: at 5' end a modified guanosine cap is added, RNA can't leave nucleus without cap, needs cap to bind to ribosomes in cytoplasm

carbohydrate - CORRECT ANSWER: A simple or complex compound composed of

carbon, oxygen and hydrogen. sugars, starches, cellulose. glycosidic bonds

carbon reduction - CORRECT ANSWER: 12NADPH and 12 ATP are used to make 12

G3P molecules and 2 carbs
