Question

S. oxyphiliae is a bacterium that can undergo fermentation or respiration. You take equal samples of the same oxyphiliae culture and supply both with equal amounts of food. You place sample A into an airtight bottle, and sample B into an open shallow container. 1. are the cells in samples A and B deriving all of their energy in the same way? Explain. 2. Will one sample run out of food faster? If yes, state which sample, and explain why. If no, explain why not. 3. at the same time when both samples run out of food, will there be approximately the same number of cells in each? why or why not? 4. in the krebs cycle itself, only one ATP molecule is generated per molecule of pyruvate. Yet we know that respiration overall yields more additional ATP molecules. Beginning with the products of the Krebs cycle, briefly outline how that additional ATP is generated.

Explanation / Answer

4. in the krebs cycle itself, only one ATP molecule is generated per molecule of pyruvate.
