Question
nsfromthe reartinn kite centernf nhotosuctem i are funneled to ATP energy to produce ATP from ADP Pi. Hydrogen ions in the thylakoid space combine with electrons from the stroma at ATP synthase, eleasing energy that can be used to produce ATP from ADP+Pi E. A hydrogen ion from NADPH is used by ATP synthase to power the production of ATP from ADP PL and an electron is released, splitting water. 39·The reactions in the thylakoid membrane provide power in the form of A. ATP and NADP+. B. ADP+ Pi. C. ADP+ Pi and NADP+. D. ATP and NADPH. E. ATP 40·ChlorophyWs to the reactions in the thylakoid membrane as is to the reactions in the A. NADP+ B. carbon dioxide C. ATP D. ATP synthase E. RuBP The following passage Is for questions 41-42 Glucose is an important compound for the production of energy. It is possible to reverse engineer glucose from pyruvate by a process called gluconeogenesis. To conserve enensy, the process of several steps of the breakdown of glucose is catalyzed by the same enzymes as in gluconeogenesis. According to the figure, the star indicates that the reaction is catalyzed by different enzymes 41. Where is this reaction taking place? Glucose 6 A. Mitochondrial Matrix B.

Aerobic Pathway 1,3, Bisphosphoglycerate C. Dark reaction 3-Phosphoglycerate D. Photorespiration E. None of the above 43. When too many nutrients are added to of a body of water, this is known as A a blogeochemical cycle. B. reservoirs c. 2-Phosphoglycerate uvate Pyruvate D. global warming E. nitrogen fixing.Explanation / Answer
39) answer is "A"
the chemical reactions in which water is oxidized to oxygen, NADP is reduced, and ATP is formed are known as the thylakoid reactions because almost all the reactions up to NADP reduction take place within the thylakoids.
40) answer is "B"
the dark reaction( light-independent reaction) occurs in the stroma of the chloroplasts when the products of the light reaction, ATP and NADPH, are used to make glyceraldehyde 3-phosphate from the reduction of carbon dioxide.
41) answer is "D"
glycolysis is an oxidative process in which one mole of glucose is partially oxidized into the two moles of pyruvate in a series of enzyme-catalyzed reactions. glycolysis occurs in the cytosol (the aqueous component of the cytoplasm of a cell).
42) answer is "A" and "B"
glycolysis is a unique pathway that occurs in both aerobic as well as anaerobic conditions and does not involve molecular oxygen.
43) answer is "C"
The eutrophication is the process of enrichment of a water body with nutrients, usually with an excess amount of nutrients is leads to the blooms of algae.
