Question Answer Prepared by: A.McDonough WHS A-200 ANSWER: Plants contain chlorophyll which reflects green wavelengths. QUESTION: Why do plants appear to be green? (Explain in terms of light)

Question Answer Prepared by: A.McDonough WHS A-300 ANSWER: Stomata QUESTION: How do gases enter and leave the leaf?

Question Answer Prepared by: A.McDonough WHS A-400 ANSWER: Light Reaction-Thylakoid Calvin Cycle- Stroma QUESTION: Where in the leaf do the light reaction and the Calvin Cycle occur?

Question Answer Prepared by: A.McDonough WHS A-500 ANSWER: Electrons are coming from the splitting of water molecules. QUESTION: The electrons that are lost from photosystem II must be replaced. What is the source of electrons?

Question Answer Prepared by: A.McDonough WHS ANSWER: Electrons, and thus energy are transferred. Loss of electrons= Oxidation Gain of electrons= Reduction QUESTION:What is a redox reaction? B-100

Question Answer Prepared by: A.McDonough WHS B-200 ANSWER: C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O QUESTION: What is the balanced equation for cellular respiration?

Question Answer Prepared by: A.McDonough WHS B-300 ANSWER: Glycolysis, Krebs Cycle, ETC, Chemiosmosis QUESTION: What are the stages of cellular respiration (In order please!)

Question Answer Prepared by: A.McDonough WHS B-400 ANSWER: Krebs cycle, ETC, Chemiosmosis QUESTION: If there is not oxygen available to the cell what 3 stages of cellular respiration cannot occur?

Question Answer Prepared by: A.McDonough WHS B-500 ANSWER: NADH, ATP, Pyruvate QUESTION: What are the 3 products of glycolysis that are needed in later steps of aerobic cellular respiration?

Question Answer Prepared by: A.McDonough WHS C-100 ANSWER: A-T G-C QUESTION: What are the complementary base pairs found in DNA

Question Answer Prepared by: A.McDonough WHS C-200 ANSWER: Nitrogen bases, Phosphate groups, deoxyribose QUESTION: What are the three parts of a DNA nucleotide?

Question Answer Prepared by: A.McDonough WHS C-300 ANSWER: Two identical strands of DNA are produced each consisting of one original parent strand and a newly constructed daughter strand. QUESTION: What does semiconservative replication of DNA mean?

Question Answer Prepared by: A.McDonough WHS C-400 ANSWER: Because DNA polymerase is directional and the DNA strands run in opposite directions, one strand will be constructed in fragments. QUESTION: What are Okasaki fragments and why do they occur?

Question Answer Prepared by: A.McDonough WHS C-500 ANSWER: Ligase QUESTION: What enzyme will connect Okasaki fragments?

Question Answer Prepared by: A.McDonough WHS D-100 ANSWER: Photosynthesis QUESTION: Which reaction takes inorganic carbon and uses it to create organic molecules, increasing biomass?

Question Answer Prepared by: A.McDonough WHS D-200 ANSWER: Photosynthesis- H 2 O Cellular Respiration- Air QUESTION: What is the source of oxygen gas in both reacions?

Question Answer Prepared by: A.McDonough WHS D-300 ANSWER: A H+ concentration gradient is produced that will in turn be used to produce ATP in chemiosmosis. QUESTION: What are two effects of the electrons passing through an ETC?

Question Answer Prepared by: A.McDonough WHS D-400 ANSWER: Photosynthesis-endergonic QUESTION: Which reaction is an endergonic reaction? Why?

Question Answer Prepared by: A.McDonough WHS D-500 ANSWER: Cellular Repiration QUESTION: Which reaction occurs in all living cells?

Question Answer Prepared by: A.McDonough WHS E-100 ANSWER: Alone, the mouse will use up the oxygen in cellular respiration. The plant replenishes oxygen in the process of photosynthesis. QUESTION: If a mouse is placed in a closed container it will die. If a plant is placed in the container along with mouse it will survive. Why?

Question Answer Prepared by: A.McDonough WHS E-200 ANSWER: Plants need light for the light reaction in order to produce ATP and NADP for carbon fixation (Calvin Cycle) and thus the production of sugars. QUESTION: A plant placed in a dark room will die. An animal in a dark room can survive. Why?

Question Answer Prepared by: A.McDonough WHS E-300 ANSWER: The carbon dioxide and water that has been used in photosynthesis to create biomolecules. QUESTION: A tree is planted in a pot of soil. After 5 years the soil has lost a mass of 4gms. The tree has gained a mass of 200kg. Where does the mass come from?

Question Answer Prepared by: A.McDonough WHS E-400 ANSWER: Radioisotopes can be detected. Thus we can detect the carbon compounds that are being built with the C radioisotope. QUESTION: Calvin placed plants in sealed containers with radioisotope-marked carbon dioxide. How did this help him uncover the steps of the light independent cycle of photosynthesis?

Question Answer Prepared by: A.McDonough WHS E-500 ANSWER: Radioisotopes containing P could trace the DNA of cells infecting bacteria, the radioisotopes of S would be left with the protein coats of viruses outside of the infected cells. QUESTION: How did using viruses containing radioisotopes of P and S help scientists determine if nucleic acids or proteins were the source of genetic material?

Question Answer Prepared by: A.McDonough WHS FINAL JEOPARDY ANSWER: STUDY! QUESTION: How can you get an A on the QPA?
