In vertebrates this protein is found in retinal cells, where it transduces the energy of light into a nerve signal to the brain.

在脊椎动物中这个蛋白主要存在于视网膜细胞中，在那里它将光能转化为传入大脑的神经信号。

Before we complete, we ask you to do something very special. Take a moment, and direct your energy to feel the energy of Light, of Angels.

在我们完成之前，我们要求你们做一些非常特殊的事情。花一小会儿，并且制定你的能量取感受“光的能量”，“天使的能量”。

The collective energy of light I am speaking of is an angelic realm that is deeply connected to humanity and earth because it helped to create man and earth.

我所谈到的集体光能是一个天使王国，它与人类和地球的关系很密切，因为是它帮助创造了人类和地球。

Plants naturally take in carbon dioxide they need for photosynthesis, the process of changing light energy to chemical energy.

And what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.

我们预测，两个能级之间的能量差，我们知道，它要么和发出的光有关,如果它发出光子的话，要么它吸收光子,从低能级跃迁到，更高能级上去。

No, OK and that's correct, because each photon of light actually has more energy than is needed to eject an electron.

没有，好，对了，因为每一个光子实际上,都有更多的能量去逐出一个电子。

When this sort of star implodes, to create a black hole, it generates jets of material that punch their way out of the collapsing mass at near light-speed, to produce extremely high-energy emissions of light.

Using different types of light bulb can also help reduce energy usage and makers of light emitting diodes (LEDs) have seen demand surge.

When a current is applied across the sandwich, the electrons and holes team up at the junction of the two materials and release energy in the form of light.
