Transcript of A Carbon Atom Through Photosynthesis and Cellular Respiration

A Carbon Atom Through Photosynthesis and Cellular Respiration Animal Cell Plant Cell This is the Cell Membrane of the Animal Cell The Cytoplasm is the Jelly-like substance that is in the cell. This is the nucleus of the cell. It is the storehouse for all DNA. Animal cells only have mitochondrion So all the energy goes through chemical reactions here for cellular respiration Onto the Plant Cell The Plant Cell has both a Cell Membrane AND and Cell Wall for protection. The cytoplasm is in both types of cells Both also have a nucleus Now Plant Cells have both mitochondrion AND Chloroplast The chloroplast does all the photosynthesis for the plant The Carbon Atom will be taking the journey through Photosynthesis first,
since CarbonDioxide is a reactant (or first element) of the entire cycle. Photosynthesis C O O C The Chloroplast The Carbon Atom starts out in photosynthesis as part of a CarbonDioxide molecule Carbondioxide is broken down into oxygen and carbon Photosystems II and I begin The Photosystems create only a few ATP in the stroma and the thylakoid membrane that can be used later After the Photosystems (Light-dependent reactions) have finished, the Calvin Cycle (Light-independent reaction) starts. This is where the carbon atoms are rearranged many times to create a glucose molecule. Many ATP molecules are made after this step. They are then used for energy throughout the plant of where it needs the energy most. Oxygen is also released from Photosynthesis The Oxygen and the Carbon-based molecules are then released. The animal cell then takes in the glucose and the oxygen for cellular respiration. The Mitochondria C C C C C C The Glucose molecule enters the mitochondria for cellular respiration, but before anything else can happen, the molecule must go through Glycolysis, which is the breakdown of Glucose, because it's too big of a molecule. Glycolysis happens in the cytoplasm first, then it is transported to the mitochondria. Once the Glucose molecule is broken down into Pyruvate, it enters the Krebs Cycle in the mitochondria. A few ATP are made in both Glycolysis and the Krebs Cycle. The carbon molecule is then trasnformed and rearranged many more times. The process of the electron transport chain is then in occurance. Many ATP are made here. The ATP is then used throughout the cell and through the body for all of its needs. The carbon atom is then transfered through the entire cycle again. Without this cycle, we would be functioning a very different way, or maybe not at all. And thus, It is the journey of... The Carbon Atom continues over to the animal cell, where it will be processed and rearranged again to produce ATP for the animal/ human. Cellular Respiration C
