Photosynthesis Light Reactions Diagram

A clean Swiss-grid scientific diagram of the light-dependent reactions of photosynthesis occurring in the thylakoid membrane. The membrane is shown as a horizontal teal band across the middle of the image. Photosystem II (labelled "PSII") on the left emits electrons (white dots with motion lines) to a plastoquinone carrier (orange hexagon, "PQ"). The electron transport chain is shown as a sequential chain of protein complexes (rectangular blocks in blue gradients). Photosystem I ("PSI") on the right feeds into ferredoxin ("Fd") and NADP+ reductase producing NADPH (labeled green flask). ATP synthase complex (mushroom silhouette) spans the membrane in the center with H+ ions flowing downward, labeled "ATP synthesis". Sunlight arrows (yellow lightning bolts) strike PSII and PSI from above. White background, primary CMYK palette, 1.5 pt rule lines, 9 pt Helvetica-style labels throughout.

一幅瑞士网格风格的光合作用光反应科学图，场景设于类囊体膜。青色横带代表膜。左侧 PSII 发出电子（白色小点加运动线）传递至 PQ（橙色六边形）；蓝色渐变矩形块代表电子传递链蛋白复合体；右侧 PSI 连接 Fd 与 NADP+ 还原酶，产生 NADPH（绿色烧瓶标注）。ATP 合酶（蘑菇轮廓）位于膜中央，H+ 向下流动，标注 「PSII」。黄色闪电箭头从上方照射 PSII 与 PSI。白色背景，CMYK 配色，Helvetica 风格 9 pt 标签。
