2C. A “pulse-chase" experiment using "C-labeled glucose can be carried out on a yeast extract that is maintained under strictly anaerobic conditions. The experiment consists of incubating a small amount of "C-labeled substrate (the pulse) with the yeast extract just long enough for each intermediate in the fermentation pathway to become labeled. The label is then “chased" through the pathway by the addition of excess unlabeled glucose. The chase effectively prevents any further entry of labeled glucose into the pathway. 2 ADP 2 ATP Glucose ---> CH3 2 NAD* 2 NADH 2 Pyruvate H H H-C-OH C=0 CH3 CH3 2 co, 2 Ethanol 2 Acetylaldehyde (1) If [1-"C]glucose (glucose labeled at C-1 with "C) is used as a substrate, will there be any "C in the product (ii) Lactic acid is the final fermentation product in vertebrates, while ethanol is the final fermentation product in yeast.

J. C. Servaites, in Plant Physiol. (1985) 78:839–843, observed that Rubisco from tobacco leaves collected before dawn had a much lower specific activity than the enzyme collected at noon. This difference persisted despite extensive dialysis, gel filtration, or heat treatment. However, precipitation of the predawn enzyme by 50% (NH4)2SO4 restored the specific activity to the level of the noon-collected enzyme. Suggest an explanation.

Inorganic Nitrate (N03-) contaminated the soil around their plant. Scientists developed mechanisms for removing Nitrite (N02-) from the soil, but have not found one for Nitrate (N03-). Is there any types of bacteria that could metabolize Nitrate (N03-) to give rise to Nitrite (N02-)? Indicate ALL metabolic pathways that could be used (aerobic respiration, anaerobic respiration, aerobic chemolithotrophy, and anaerobic chemolithotrophy) to carry out this reaction? Which of these reactions can oxidize or reduce inorganic materials
