cone pigments 中文意思是什麼
-
Rhodopsin is similar in both structure and absorption characteristics to the cone pigments most sensitive to wavelengths in the middle of the visual spectrum, and it evolved from those pigments hundreds of millions of years ago
就構造與吸收光譜特性而言，視紫質與中波長錐色素最為相似；幾億年前，視紫質從這些中波長錐色素演化了出來。 -
The more intense a light, the more photons are absorbed by the visual pigments, the greater the excitation of each cone, and the brighter the light appears
光越強，視色素吸收到的光子數目就越多，每個錐細胞的興奮程度也越大，所感受到的光也就越亮。 -
We can trace four lineages of vertebrate cone pigments, named descriptively after the spectral region in which they are most sensitive : long - wavelength, mid - wavelength, short - wavelength and ultraviolet
我們可以追溯出脊椎動物四種錐細胞視色素的演化路徑，名稱分別反應出它們最敏感的光譜波段：長波長、中波長、短波長與紫外光。 -
Mammals, however, typically have only two cone pigments, one maximally sensitive in the violet and the other sensitive at long wavelengths
但哺乳動物通常只有兩種錐色素，一種對紫光最敏感，另一種則對長波長的光敏感。 -
Consequently, they lost two of the four cone pigments that their ancestors once possessed ? pigments that persist in most reptiles and birds
於是哺乳動物喪失了祖先曾經擁有四種錐色素中的兩種，而這些錐色素則仍保存在多數的爬行類與鳥類身上。
