Unit 3 Reflection

     In this unit, the 2 major concepts we learned were photosynthesis and cellular respiration.

     Photosynthesis is the process of making sugar or glucose for the plat to grow. There are are light independent and light dependent reactions. One process, known as the Calvin cycle, uses carbon dioxide (CO2) and enzymes to produce these sugars that the pant needs. A light dependent reaction requires light in order to function. Their is a organelle in the plant cell called the chloroplast that converts solar energy into sugar with water (H20) and carbon dioxide and it produces Oxygen (O2) and sugar.

     Cellular respiration takes place in the mitochondria and requires oxygen and sugar to produce carbon dioxide, water, and ATP. ATP is one of the only molecule that can be "recharged" through adding one phosphate molecule. their are thee steps in cellular respiration, the first being Glycolysis, the second is the Krebs Cycle, and lastly the Electron transport chain. Glycolysis requires 2 ATP and occurs in the cytoplasm for every glucose molecule. The next step is the Krebs Cycle or the Citric acid Cycle. This step needs glucose to form 2 ATP, CO2, and electron carrying molecules. The next step named Electron Tranceport Chain occurs in mitochondria and uses oxygen, NADH, and FADH to convert ADP to ATP. This whole process produces 36 ATP, 6 molecules of CO2, and 6 molecules of H2O.
     In this unit the most trouble I had was trying to memorize all the steps to cellular respiration
     I would like to learn more about cellular respiration because I felt like it was the most interesting but photosynthesis was a close second. 
     From my experiences of this unit I now know how complicated plat or animal can be. but we only scratched the surface of that.
