← ScienceWhich consequence results when electron orbitals hybridize incorrectly in cytochrome oxidase?
A)Decreased oxygen reduction ATP synthase activity✓
B)Accelerated protein folding chaperone availability
C)Increased superoxide dismutase mRNA expression
D)Enhanced oxidative phosphorylation uncoupler selectivity
💡 Explanation
Incorrect hybridization alters the catalytic site geometry, leading to decreased oxygen binding and thus reduced function; therefore, oxidative phosphorylation is impaired rather than enhanced, because electron transfer is altered, rather than superoxide production.
