A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations? The mutation is disrupting glycolysis.
The mutation is disrupting fermentation.
The mutation is disrupting the citric acid cycle.
The mutation is disrupting the electron transport chain.
