线粒体 ATP 合成循环图

一幅线粒体 ATP 合成的等轴测扁平科学信息图。线粒体以 3/4 等轴视角斜切，暴露出内膜（深红色嵴状结构）。内膜上的呼吸链复合体（I-IV）从左至右以彩色矩形块表示：复合体 I（板岩蓝）、II（橄榄绿）、III（酒红）、IV（铁锈红）。NADH（黄色箭头）和 FADH2（绿色箭头）喂入电子传递链；橙色小上箭（H+）堆积于膜间隙。ATP 合酶（涡轮图标）在右端，ADP+Pi 进入，琥珀色发光箭头表示 ATP 输出。线粒体基质中有柠檬酸循环小圆圈。暗泥土色调，9 pt 标签，细胞器外为深海蓝背景。

An isometric flat scientific infographic of ATP synthesis in a mitochondrion. The mitochondrion is shown in isometric 3/4 view, sliced diagonally to expose the inner membrane (deep-red corrugated cristae on a maroon interior). On the inner membrane, the respiratory chain complexes (I, II, III, IV) are shown as color-coded rectangular blocks from left to right: Complex I in slate-blue, Complex II in olive, Complex III in burgundy, Complex IV in rust. Electron carriers (NADH — yellow arrow, FADH2 — green arrow) feed into the chain. H+ proton gradient arrows (small orange upward chevrons) accumulate in the intermembrane space. ATP synthase (Complex V) is shown as a turbine icon at the far right, with ADP+Pi entering and ATP exiting via a glowing amber arrow. Citric acid cycle wheels (small clockwise circle) connect to the matrix. Muted earthy palette, 9 pt labels, dark navy background outside the organelle.
