Question

The minerals involved in water-splitting reaction during photosynthesis are ___________

(a) Manganese and chloride

(b) Magnesium and sulfur

(c) Magnesium and potassium

(d) Magnesium and phosphorus

I got this question in semester exam.

I'm obligated to ask this question of Cell Nutrients in portion An Overview of Biological Basics & Enzymes of Bioprocess Engineering

Answer 1

The correct answer is (a) Manganese and chloride

The best I can explain: Water splitting is catalyzed by the oxygen-evolving complex (OEC) of protein complex photosystem II (PSII), producing dioxygen gas, protons and electrons. O (2) is released into the atmosphere, sustaining all aerobic life on earth; product protons are released into the thylakoid lumen, augmenting a proton concentration gradient across the membrane; and photo-energized electrons pass to the rest of the electron-transfer pathway. The OEC contains four manganese ions, one calcium ion and (almost certainly) a chloride ion.
