This school year, there are 12 students who are enrolled in the AP Biology course, which is a college-level biology class. This course is opened for students to sign up, personally I signed up for this class because I want to understand the natural world around me, and the living organisms within our world. In addition, I believe that it would be helpful to understand the basic of this field especially because I want to attend medical school.
In this first term, we learned about Ecology Biology and we’re introduced to the Cell Unit. To further our understanding of the Eukaryotic Cell, our facilitator assigned each student with an organelle. Students had to do research regarding the functions of their organelle, and share the information with other students, by simulating that we are being interview for different job’s position of a company. So each student had to pretend to be their organelle, and tried to convince the facilitator and other student why they (the organelles) are important for a company.
Here is my speech as peroxisome, trying to convince others to hire me as an employee.
Hello, My name Peroxi-glyoxy.
Let me get one thing straight, I might not be able to move around the company by myself, however I have good communication skill that allow be to hitchhike other endosomes to move to places, and with all my skills you’ll be amazed on how I do this nearly all by myself.
Okay, so I understand that this company has cell wall to maintain the security of the company. Provide shield so that outsiders can’t intrude the business. But while cell wall is busy doing its jobs, sometimes there are enemies within our company, the one that can’t be killed by cell wall or any other employees. Such as hydrogen peroxides that can destroy the cell wall. Therefore I believe that both animal and plant department needs someone like me to be a staff member.
So at first glance, I might look like lysosomes, or one of the microbodies. However, we have a totally different role, actually roles.
I have over 50 different enzymes, that can be use to help and secure the company in different variety of biochemical ways.
As I have mentioned a second ago, hydrogen peroxide are really harmful for a company, since it is a by product of digestion, we can’t just stop getting energy to get rid of this H2O2, there for you should hire me. One of my enzymes call catalase is used to break down hydrogen peroxide, and convert it into water. For me since hydrogen peroxide can’t do me harm, I can use this toxic to break down other organic compound such uric acid, amino acids, and fatty acid though the process of oxidation. In addition, the oxidation of fatty acid can provide a major source of metabolic energy, the process of oxidizing fatty acid can be done by mitochondria and peroxisomes in the Animal Department, however for the plants department this job is only restricted to me.
For the Animal department, I can also do helps some other jobs such as synthesize cholesterol and dolichol those that use to make hormones, vitamin D, and digestive fluids, and especially in the Human sector of animal department, I also help to produce bile acid for the liver. And help with some aspect of energy metabolism.
For Plant department, I play a great role on converting of stored fatty acids to carbohydrates in seeds, so germinating plant has energy and raw materials that can be used for growth whereby here I am known as glyoxysomes or peroxisomes.
In the Leaves sector of the plant, I, peroxisome also involved in photorespiration, by allowing most of the carbon in glycolate to be recovered and utilized.
You must hire me because I am a hard worker and an essential aspect for the company to keep running.
