| 中文简介: |
在这门课程中，你们将穿越物理、化学和生物反应的网络，这些反应共同构成光合作用。我们将从光收获开始，跟随光子到初级光化学的位置:光反应中心。分子尺度的观点将显示这些蛋白质复合物如何捕获和激发电子的原子细节。然后，我们将遵循电子在执行其工作时所采取的多种途径。后续反应，如ATP的合成和碳水化合物合成过程中CO2的还原，也将在结构细节上进行讨论。最后，我们将深入研究这些系统的进化，并讨论其他光合作用策略，如光驱动质子泵和无氧光合作用。本课程将包括参观电子显微镜，让学生直接观察与光合作用有关的蛋白质。这门课程是麻省理工学院生物系提供的许多高等本科生研讨会之一。这些研讨会是为有兴趣利用初级研究文献在高度互动的环境中讨论和学习当前生物研究的学生而设计的。许多本科生高级研讨会的讲师都是对教学有浓厚兴趣的博士后科学家。

| 课程简介: |
In this course, you will journey through the web of physical, chemical, and biological reactions that collectively constitute photosynthesis. We will begin with light harvesting and follow photons to the sites of primary photochemistry: the photoreaction centers. A molecular-scale view will show in atomic detail how these protein complexes capture and energize electrons. Then we will follow the multiple pathways electrons take as they carry out their work. Consequent reactions, such as the synthesis of ATP and the reduction of CO2 during the synthesis of carbohydrates, will also be discussed in structural detail. Lastly, we will delve into the evolution of these systems and also discuss other photosynthetic strategies, such as light-driven proton pumps and anoxygenic photosynthesis. The course will include a visit to an electron microscope to allow students to directly observe proteins involved in photosynthesis. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.
