Biology 1 Exam 3 Questions with Answers Latest Update

How is ATP made? - Correct Answershydrogen bonds Where does photosynthesis occur? - Correct Answersthylakoids Why is water split during photosynthesis? - Correct Answersto release O2 and get hydrogen atoms where does the oxygen go in photosynthesis? - Correct Answersreleased into the air what accepts the light energy in photosynthesis? - Correct Answersthe pigments how many ATP are used per calvin cycle? - Correct Answers How many NADPH are used in the Calvin Cycle? - Correct Answers how many calvin cycles are needed to produce a 6 carbon sugar? - Correct Answers balanced formula for respiration - Correct AnswersC6H12O6+6O2+6H2O—

energy+CO2+12H2O Balanced formula for photosynthesis - Correct Answers6CO2 + 12H2O + light ------> C6H12O6 + 6O2 + 6H2O the O2 in the CO2 that you breathe out comes from where? - Correct AnswersBlood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.

if an organism lived on a planet without breathable oxygen but had access to a lot of sugars, would it survive? - Correct Answersyes, the organism would go through glycolysis and then an aerobic process of fermentation to make ATP how many mitochondria in a plant cell? - Correct Answersa lot how many chloroplasts in an animal cell? - Correct Answersnone primary function of calvin cycle - Correct Answerssynthesis simple sugars from CO your friend lost a lot of weight. how did the weight leave her body? - Correct Answersconverts to urine and is eliminated from body the O2 consumed during a cellular respiration is involved in which process? - Correct Answersaccepting electrons at the end of the electron transport chain When O2 is released as a result of photosynthesis, it is a direct by-product of - Correct Answerssplitting water molecules A plant has a unique photosynthetic pigment. The leaves of this plant appear to be reddish yellow. What wavelengths of visible light are being absorbed by this pigment? - Correct Answersblue and violet (every color but yellow and red) The reactions that produce molecular oxygen (O2) take place in - Correct Answersthe light reactions alone In addition to ATP, what are the end products of glycolysis? - Correct AnswersNADH and pyruvate in cellular respiration the energy for most ATP synthesis is supplied by - Correct Answersa protein gradient across a membrane During glycolysis, when each molecule of glucose is catabolized to two molecules of pyruvate, most of the potential energy contained in glucose is - Correct Answersretained in the two pyruvates

if you are in a forest at night, what will happen to CO2 levels? - Correct AnswersCO2 will rise as a result of both animal and plant respiration which layer of leaf contains the majority of the chloroplasts? - Correct Answersepidermis in photosynthesis, electrons from photo system 1 are passed down an electron transport chain and donated to what? - Correct AnswersNADP+ the electrons that leave photo system 2 are replaced with electrons donated by which of the following? - Correct Answerswater which of these molecules is produced during the light dependent stage of photosynthesis?

  • Correct AnswersNADPH and ATP the wavelength of light that the chlorophyll a pigment found at the reaction center in photo system 1 absorbs is: - Correct Answers700nm would the following figure best represent photosynthesis or respiration. why? - Correct Answersphotosynthesis because it is an endergonic process and is not spontaneous. it brings in the light from the sun what is meant by an absorption spectrum? how is that important in photosynthesis? - Correct Answersit is what colors the leaves absorb from the sun. when the light hits it, it shoots the electron up the gradient. what is the ultimate electron acceptor for photosynthesis - Correct AnswersNADPH How many ATP are created in glycolysis? - Correct Answers net gain/loss of ATP in glycolysis - Correct Answers Where does glycolysis occur? - Correct Answerscytosol how many ATP are expended in glycolysis - Correct Answers

what is removed and added to the original molecule in the oxidation of pyruvate - Correct AnswersCO2 removed, coenzyme A and NADH+H is added where does oxidation of pyruvate occur - Correct Answersmitochondria how many carbons are lost in the krebs cycle? - Correct Answers how many ATP are produced/expended per krebs cycle? - Correct Answers how many NAD+/NADH are produced/expended per krebs cycle? - Correct Answers how many FADH2 are created/expended per krebs cycle - Correct Answers how many cycles does the krebs cycle run per glucose molecule - Correct Answers Where does the Krebs cycle occur? - Correct Answersmitochondria What molecules are created at the end of the electron transport chain - Correct AnswersATP Where does the electron transport chain occur? - Correct Answersmitochondria How many ATP are created in the electron transport chain - Correct Answers26- 32 Where does the energy to create ATP come from in the electron transport chain - Correct Answershydrogen atoms What are the advantages and disadvantage is of alcohol fermentation - Correct Answersadvantage = you get more energy disadvantage = it takes longer Identify an organism that uses alcohol fermentation - Correct AnswersYeast

What are the advantages and disadvantages of lactate fermentation - Correct Answersadvantage = faster process disadvantage = doesn't produce much energy Identify an organism that uses lactate fermentation - Correct AnswersHumans
