Question

what is the first photosystem in the thylakoid membrane called? photosystem ii photosystem i chlorophyll glycolysis

Explanation:

In the light - dependent reactions of photosynthesis in the thylakoid membrane, the first photosystem is photosystem II. It is named so despite being the first in the sequence of electron - transfer reactions. Chlorophyll is a pigment involved in photosynthesis but not a photosystem. Glycolysis is a part of cellular respiration, not related to photosystems in the thylakoid membrane.

Answer:

photosystem II
