Upgraded B002 Ntbi1003 Site Textmn Action Photosystem — a labelled NEET Biology diagram with a definitions lexicon.
Diagram showing the specific site of Mn 2+ action in Photosystem II. Labelled parts: Electron Transport Chain, Photosystem II, Cell Division, Photosystem I, Chloroplasts, Chloroplast, Enzyme, Growth, Auxin, Androecium, Catalytic Roles. A series of membrane-bound carriers that transfer electrons via redox reactions to generate a proton gradient for ATP production. FYI: In mitochondria, the final electron acceptor is oxygen, whereas in chloroplasts, the final acceptor in non-cyclic flow is NADP+. A protein-pigment complex in the thylakoid membrane that absorbs light at 680 nm and initiates non-cyclic electron transport. FYI: It is uniquely associated with the oxygen-evolving complex (OEC) which performs the photolysis of water. The process by which a parent cell divides into two or more daughter cells, essential for growth and reproduction. FYI: In unicellular organisms, cell division is synonymous with reproduction, increasing the population size. A protein-pigment complex in the thylakoid membrane that absorbs light at 700 nm and participates in both cyclic and non-cyclic photophosphorylation. FYI: In non-cyclic transport, PS I receives electrons from PS II via the mobile carrier plastocyanin. Organelles in plant cells responsible for photosynthesis, containing chlorophyll. A double-membraned plastid containing chlorophyll pigments that performs photosynthesis to convert light energy into chemical energy. FYI: Chloroplasts are found mainly in the mesophyll cells of leaves and are thought to have evolved via endosymbiosis. A biological catalyst, usually a protein, that accelerates chemical reactions by lowering the activation energy. FYI: Almost all enzymes are proteins, except for ribozymes which are catalytic RNA molecules. Increase in size or mass; can occur in non-living matter like crystals. A plant hormone that promotes root initiation and apical dominance. The androecium is the collective term for all the stamens of a flower. Each stamen consists of an anther (pollen-producing sac) and a filament. FYI: The number of stamens can be used to classify plants; for example, in the family Fabaceae, the androecium is often diadelphous (9+1 arrangement). Catalytic Roles is a labeled feature or concept in this upgraded BioAtlas image: A highly labeled diagram of the thylakoid membrane within a chloroplast, specifically highlighting the Oxygen-Evolving Complex (OEC) where Mn ions are critical for water splitti...
