电子传输链：产生能量的过山车

这是全长的“电子传输链”模拟。对于较短的，更具针对性的版本，请参见下面的相关模拟。华体会赞助ac米兰

In the Electron Transport Chain simulation, you’ll meet Roxy, the lead engineer for a project in north Alaska. Here, environmental protection has been made a priority. With VR, you will fly over the ocean on a journey to discover that the most problematic facilities are the coal power plant and the fish farm, which are causing glacier melting and eutrophication. But fear not, Roxy has come up with a brilliant idea to produce biofuel from algae using the excess of nutrients from the fish farm and the heat and CO2 from the coal plant. When scuba diving, she found some mysterious dark algae and now she needs your help to figure out if the algae can use green light to perform photosynthesis.

Use the Hill reaction and spectrophotometry

Most plants are green, so they reflect this colour and absorb other wavelengths, which they use for photosynthesis. However, green is a major component of the visible light spectrum, so combining algae that use green light with algae that use other wavelengths maximises the use of sunlight. In this simulation, you will use the Hill reaction and spectrophotometry to measure electron flow and find out if the pigments can use green light for photosynthesis.

看叶绿体内部

To understand how photosynthesis works, you will shrink to a tiny size and see what happens during the electron transport chain. You will be able to click on the different molecules to see electrons and protons moving, water molecules splitting and the ATP synthase spinning around to pump protons and produce ATP.

Don’t forget your controls!

One博士已经为您提取了颜料。有一个虚拟助手可能非常方便！现在，要查看颜料是否可以使用绿灯，您将设置一个实验。为了正确检验您的假设，您需要准备和测量样本以及阳性和负面对照。

Measure photosynthesis

山丘反应使用DCPIP，一种氧化还原染料，有助于测量来自光系统II的电子流。通过将仅在分光光度计中暴露于绿光的色素样品的吸收光谱与控件的吸收光谱与对照组的吸收光谱，您将能够弄清黑藻是否能够使用绿光进行光合作用。
