visual pigment 中文意思是什麼
visual pigment
解釋
視覺色素-
Some wavelengths are absorbed better than others, and each visual pigment is characterized by a spectrum that describes how absorption varies with wavelength
這是因為錐細胞對不同波長的吸收能力不同,而且,每個視色素的差異在於其吸收光譜,也就是對不同波長的吸收率差異。 -
A visual pigment may absorb two wavelengths equally, but even though their photons contain different energies, the cone cannot tell them apart, because they both cause the retinal to change shape and thus trigger the same molecular cascade leading to excitation
同一個視色素可能對兩種不同波長的吸收能力一樣好,但即使這兩種波長的光子能量不同,錐細胞也無法將之區分開來,因為這兩種光都會改變視黃醛的形狀,因而引發同樣的分子事件,造成錐細胞的興奮。
