Answers to Photosynthesis/Cellular Respiration Worksheet

PS:
1.  Water 
2.  Thylakoid Membrane
3.  Oxygen
4.  To pump protons from stroma to inside of thylakoid; ultimately to generate ATP as the protons flow back to the stroma
5.  ATP  and NADPH + H⁺
6.  Rubisco is light-activated (and these reactions require the products of the light reactions indicated in #5).
7.  Rubisco also fixes oxygen
8.  First molecule formed upon fixing CO₂ is a 4 carbon molecule; PEPC (PEP carboxylase)
9.  Dry and warm
10.  Open stomates at night to avoid water loss.
11.  Magnesium.

CR:
1.  NADH + H⁺
2.  Cristae of the mitochondria
3.  Oxygen molecules; they are the final electron acceptor.
4.  True
5.  38; 3
6.  Glycolysis and fermentation (aerobic respiration is glycolysis, the Krebs' cycle and oxidative phosphorylation)
7.  (two) pyruvates
8.  in the cytoplasm; to recycle NAD⁺ for use in glycolysis
9.  exergonic
10.  2; 2
11.  as waste Carbon Dioxide (produced inside the matrix of the mitochondria, mostly during the Krebs' cycle).
12.  2 carbons; Acetyl CoA

Chemiosmosis:
        A channel protein and the enzyme ATP synthetase; from inside thylkoid to stroma (inside chloroplasts); from intermembrane space to matrix of mitochondria
