给这个题目生成讲解视频---Here's the extracted content from the image: **Question (Fragment, appears to be part of a larger question sequence):** (3) 如图所示，肥胖患者的饮食中谷类和肉类的摄入量较正常人偏多，多余的能量会转化为______，作为备用能源物质储存在人体。 **Question Set 3:** 3. 2021年9月，中科院团队首次实现了在实验室反应器中人工合成淀粉这一重大颠覆性技术。下图是农作物光合作用和人造淀粉装置示意图的对比。请回答下列问题： **Chart/Diagram Description:** * **Type:** Comparative diagram/schematic illustration. * **Main Elements:** * The diagram presents two distinct processes, labeled 甲 (Jia) and 乙 (Yi), showing a comparison between natural photosynthesis and artificial starch synthesis. Both processes show a sun symbol (太阳) at the top, indicating a light source. * **Process 甲 (Plant Photosynthesis):** * A green leaf is depicted. * Arrows indicate inputs: 二氧化碳 (Carbon dioxide) entering the leaf from below, and 水蒸气 (Water vapor) exiting the leaf from above. * Arrows indicate outputs: 氧气 (Oxygen) exiting the leaf from above, and 有机物 (Organic matter) being produced and transported downwards. * The overall process utilizes sunlight. * **Process 乙 (Artificial Starch Synthesis):** * A 太阳能板 (Solar panel) is shown on the left, receiving energy from the sun (太阳). * An arrow indicates 二氧化碳 (Carbon dioxide) entering a 生物反应器 (Bioreactor) from above. * The solar panel is connected to the bioreactor via a dashed line, suggesting energy transfer. * An output labeled 淀粉 (Starch) is shown exiting the bioreactor to the right, represented by a stylized starch molecule. * **Labels:** 甲 and 乙 differentiate the two processes. **Sub-questions:** (1) 人造淀粉通过太阳能板获取能量，太阳能板相当于叶绿体中的______。 (2) 乙装置生产出的产物是否为淀粉，可以用实验室中的常用药品______来检测。 (3) 植物通过光合作用制造的有机物，由______（填“导管”或“筛管”）运输到根、茎和果实等其他器官。 (4) 淀粉属于糖类物质，对人体的重要作用是______。
