To study the mechanism of excitation in the reaction center of a photosystem, on what timescale would you need to capture data? A) Seconds B) Milliseconds (10^-³ sec) C) Microseconds (10^-⁶ sec) D) Nanoseconds (10^-⁹ sec) E) Picoseconds (10^-¹²sec)

Question

Quizplus · Accepted Answer

The mechanism of excitation in the reaction center of a photosystem involves very fast processes that occur on the picosecond timescale. This is because the excitation energy is transferred almost instantaneously among pigment molecules until it reaches the reaction center.
