2.07 Photosynthesis
Storyboard Text
- Hi, everyone. I'm Professor Richardson, and I think you need to know about photosynthesis, cellular respiration, and the transition from photosynthesis and respiration.
- In this plant cell, there is an organism called a chloroplast. The chloroplast is filled with stacks of thylakoids called grana, it has an outer and inner membrane, a stroma which is the stuff that surrounds the thylakoids, and little bridges between the grana called lamella. Chloroplasts are where photosynthesis takes place. The Process of Photosynthesis begins when plants absorb carbon dioxide and water and ends when it releases Oxygen and Glucose or sugar.
- ATP
- Cytoplasm
- Animal cells go through a different type of process. They go through cellular respiration. Cellular respiration starts when we eat and breathe and ends by releasing Carbon dioxide and water. As we all know, animals can't make their own food like plants which is why we eat and breathe.
- Goodbye
- The molecules in photosynthesis and the molecules in cellular respiration are very similar. They perform similar functions and ultimately give the animal or the plant the energy they need to survive. There are two types of reactions in photosynthesis, the light dependant reactions and the light-independent reactions. The light-dependent reactions include the release of Oxygen, ATP, and NADPH, which start the Calvin cycle, which takes in carbon dioxide and ends when it releases sugar.
- Now cellular respiration starts in the Cytoplasm of a cell, with the intake of glucose and the process of Glycolysis. It then takes the end product of Glycolysis into the Mitochondria and releases two ATP. This portion of Cellular Respiration is called the Krebs cycle. Once it's done with that, it releases two things, two ATP and Carbon dioxide. The end product of the Krebs Cycle then goes into the Electron Transport Chain, which ends by releasing Thirty Two ATP.
- Anyways, thank you for listening to my little spiel about photosynthesis and Cellular Respiration. But, for now, I bid you Adieu!
