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?

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

cells spend most of their time in interphase
