B) 5 CO_2 + 6 H_2O rightarrow C_5H_12O_6 + 6 O_2 + energy.Explanation / Answer
29. ANS: D. 36 ATP
Cellular respiration has a potential to produce between 36 and 38 moles of ATP per mole of glucose (C6H12O6).
30. ANS: C. Glycolysis
All cells can perform anaerobic respiration by glycolysis. Additionally, most organisms can perform more efficient aerobic respiration through the citric acid cycle and oxidative phosphorylation.
31. ANS: A. Glycolysis
Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
32. ANS: D. The citric acid cycle and oxidative phosphorylation
A drug is tested in the laboratory and is found to create holes in both mitochondrial membranes. Scientists suspect that the drug will be harmful to human cells because it will inhibit the citric acid cycle and oxidative phosphorylation. It is very evident that citric acid cycle occur in the matrix of mitochondria and the oxidative phosphorylation occur in the inner mitochondria membrane.
33. ANS: C. Delivers its electron load to the first electron carrier molecule in the ETC.
34. ANS: D. It is carried by electrons.
Some energy is used to produce ATP, and some energy is lost as heat. Not 100% efficient. Some energy is stored in bonds of energy carriers like ATP.
35. ANS: C6H12O6 + 6 O2 ------> 6 CO2 + 6 H2O + energy
