#Question id: 10130


manganese (Mn) is an essential cofactor in the water-oxidizing process, and a classic hypothesis in photosynthesis research postulates that Mn ions undergo a series of oxidations—known as S states, This hypothesis has received strong support from a variety of experiments, which of the following techniques detect the manganese ions directly and Analytical experiments indicate that how much Mn ions are associated with each oxygen-evolving complex?

#Unit 6. System Physiology – Plant
  1. X-ray absorption is involve to detect eight Mn ions
  2. Only magnetic-resonance technique known as electron spin resonance (ESR) are involve to detect the four Mn ions with each oxygen evolving complex
  3. Both X-ray absorption and electron spin resonance (ESR)  are involve to detect the four Mn ions
  4. Nuclear Magnetic resonance (NMR) spectroscopy is involve to detect the eight Mn ions
