Enzymes, Cellular Respiration, and Photosynthesis- Week 2

This week in biology we mainly learned more about enzymes and the processes it undergoes. We also learned about photosynthesis and cellular respiration. Photosynthesis is a chemical process through which plants produce glucose and oxygen only using light energy. It provides the oxygen in which all living organisms must have to survive! We did a small poster this week and me and my partner had photosynthesis. While researching stuff on the poster I learned that the glucose that photosynthesis creates is used during respiration to release energy. Cellular respiration is the process that uses the energy is glucose to transfer it to ATP. Cellular respiration allows organisms to use/release energy stored in the bonds of glucose. This week we also did a lab where we put raw chicken liver in hydrogen peroxide. We saw that the peroxide was breaking down the enzymes in the liver making the peroxide water. I learned alot about enzymes in this lab!
