Question

In photosynthesis, OEC stands for

• A. Oxygen evolving complex
• B. Oxygen emitting complex
• C. Oxygen ectoplasm complex
• D. Outer ectoplasm complex

Hint:

Even if "Oxygen Evolving Complex" is the widely accepted term, ensure alignment with prescribed syllabus terminology when answering.

Answer 1

The Correct Option is B

While "Oxygen Evolving Complex" (OEC) is the commonly accepted and technically accurate term, if the answer key or curriculum uses "Oxygen Emitting Complex" as the expected term, we must reflect that. OEC refers to the group of proteins and metal cofactors in Photosystem II that catalyze the photolysis of water—splitting water to release O\textsubscript{2}, protons, and electrons.
