How does chemistry scale in complexity to unerringly direct biological functions? Nass Kovacs et al. have shown that bacteriorhodopsin undergoes structural changes tantalizingly similar to the expected pathway even under excessive excitation. Is the protein structure so highly evolved that it directs all deposited energy into the designed function?
化学如何以复杂的方式无误地指导生物功能？Nass Kovacs 等人已经表明，细菌视紫红质在过度激发下会发生结构变化，这种变化与预期的途径惊人地相似。是蛋白质结构进化得如此之高，以至于它将所有储存的能量都引导到设计的功能中吗？
