75. The diagram below illustrates (a) Carbon-fixation (b) the Krebs cycle (c) Cyclic phosphorylation (d) the electron transport chain (e) the mobilization cycle
76. Products of this pathway then enter which pathway? (use choices from # 75)
77. The molecule present at every step of glycolysis and the Krebs Cycle where hydrogen is released is (a) ADP (b) FAD (c) NADP (d) PGAL (e) NAD (THINK!)
78. Water, in photosynthesis, (a) is split, with the release of O2 + removal of electrons + H+ ions (b) is added to NAD+ (c) absorbs light energy + is oxidized (d) combines with RuBP (e) combines with chlorophyll P680
79. Chlorophyll P700 is reduced by electrons that arrive directly from (a) both photosystem I + water (b) photosystem I only (c) NADPH (d) photosystem II only (e) water only
80. When H2O is formed in aerobic respiration, where do the oxygen atoms in the H2O come from? (a) pyruvate (b) CO2 (c) lactic acid (d) glucose (e) oxygen in the air
81. When H+ ions diffuse into the matrix-across the inner mitochondrial or thylakoid membrane, the result is (a) the reduction of NAD+ (b) the formation of ATP by ATP synthase (c) the hydrolysis of ATP by ATPase (d) the formation of H2O molecules for release from the cell
