Prokaryote metabolism activity

I wrote this activity to emphasize that prokaryotic organisms can carry out 6 different types of metabolisms (as presented in Freeman’s Biological Science textbook) and this contrasts to eukaryotes, which can only use 2 metabolism pathways (photoautotroph and heterotroph). For in class materials I remove the red box (upper right corner) and print slides 3-10, place them back-to-back and laminate them. The students get a key (slide 2) and a two-sided organism sheet. They are instructed to answer the questions based on the info provided. After class the slides (with the red box restored) are provided on-line as a pdf so they can use to prepare for the exam. Exam questions are taken from sheets: for example, the students may be given the picture and notes about Thaumarchaeota and asked “This organism would be considered a…. (a) prokaryote (b) eukaryote (c) fungi (d) chordate” If you have questions or improvements to this activity please email me Lori Biederman Iowa State University [e-mail]

本活动旨在强调：原核生物（prokaryotic organisms）可进行6种不同类型的代谢过程（正如《弗里曼生物学》（Freeman’s Biological Science）教材中所呈现的内容），这与仅能利用2种代谢途径的真核生物（eukaryotes）形成鲜明对比——这两种途径为光能自养型（photoautotroph）与异养型（heterotroph）。针对课堂教学材料，我会移除右上角的红色框，打印第3至10页幻灯片，将其背对背放置后进行覆膜处理。学生将获得一份答题指引（对应第2页幻灯片）与一张双面印制的生物资料单，并需根据所提供的信息作答题目。课后，我会将恢复红色框的幻灯片以PDF格式上传至线上，供学生备考使用。考试题目均取材于上述资料单：例如，学生会拿到关于泉古菌门（Thaumarchaeota）的图片与注释，并被提问："该生物应被归类为……（a）原核生物（b）真核生物（c）真菌（d）脊索动物"。若您对本活动有任何疑问或改进建议，请致信洛里·比德曼（Lori Biederman），美国爱荷华州立大学，邮箱：[e-mail]
