8291087119	noncompetitive inhibition	binds to allosteric site (not the active site) of an enzyme causing shape to change	7
8291096936	Oxidation	is the lost of an electron	8
8291101337	Reduction	is the gaining of electrons	9

8291194968	the final electron acceptor in the ETC of cellular respiration is	oxygen	14
8291206498	NADH and FADH2 job is to	carry electrons to the ETC	15
8291219752	after glycolosis if there is no oxygen available the pyruvate molecules can be converted into	ethanol or lactic acid	16
8291254227	the two functions of fermentation	produce a little ATP and oxidize NADH to NAD+	17
8291271838	What occurs as the electrons move from protein to protein in the ETC of cellular respiration?	H+ protons are pumped out into the intermembrane space	18
8291277583	ATP synthase	produces ATP	19
8291280327	Chemiosmosis	the diffusion of ions (H+) from area of high concentration to an area of low concentration	20
8291301627	as the electron passes through the ETC the proteins embedded in the inter mitochondria membrane	alternate between being reduced and being oxidized	21
8291315502	oxygen produced in the light reactions of photosynthesis comes from	the water	22
8291331871	what are the products of the light reaction of photosynthesis	Oxygen, ATP, NADPH	23
8291352725	where do the light reaction take place?	thylokoid membrane	24
8291357896	what replaces the electron lost by P680	the electrons from the splitting of water	25
8291370057	what replaces the electrons lost by P700	the electrons from P680 that has traveled down the ETC	26
8291388022	RuBP is a 5 carbon molecule that	combines with CO2 in the Calvin Cycle	27
8294049427	what enzyme combines RuBP with CO2	RuBisCo	28
8291437955	the primary function of the Calvin Cycle is to produce	G3P/PGAL that will be used to make glucose	29
8291541422	CAM plants keep stomata close in the daytime and are able to fix CO2 into ______________________	organic acids during the night and covert it back to CO2 in the morning to undergo the Calvin Cycle	30
8291555332	photorespiration	uses oxygen instead of CO2 in the Calvin cycle	31
