Question

what systems are embedded in the thylakoid membrane? citric acid cycle enzymes ribosomal secretion proteins photosystem i and photosystem ii

Explanation:

The thylakoid membrane is part of chloroplasts and is involved in photosynthesis. Photosystem I and Photosystem II are protein - pigment complexes embedded in the thylakoid membrane that are essential for the light - dependent reactions of photosynthesis. Citric acid cycle enzymes are involved in cellular respiration and are located in the mitochondrial matrix (and some in the inner mitochondrial membrane), not in the thylakoid membrane. Ribosomal secretion proteins are related to ribosomes and the process of protein secretion, and they are not embedded in the thylakoid membrane.

Answer:

photosystem I and photosystem II
