Question: How does the presence of light affect the production and consumption of carbon dioxide in plants?
The initial energy that lights gives to the chloroplasts ultimately affect the amount of carbon dioxide that is consumed and produced. To start the light dependent stage of photosynthesis, sunlight is needed for the initial energy in which the chlorophyll in the chloroplast harnesses. Water is taken in by the xylem tissues in the roots. The water molecules are split and oxygen is released into the air. The same oxygen we are using to breathe currently. The other product of the water splitting is the hydrogen ions. The light is there to power the transport of the hydrogen molecules through each Photosystem with the electron transport chain. Each photosystem is made up of proteins with chlorophyll on the inside. The …show more content…
Light is being introduced at both Photosystem two and one. This all occurs in the thylakoids of the chloroplasts. The process converts the original sunlight and the splitting of the water molecules into ATP and NADPH. The light independent reactions use the ATP and NADPH that was made in the light dependent reactions to produce food(sugars) for themselves and indirectly humans. ATP and NADPH with the help of the enzyme rubisco is able to speed up the chemical reaction used to fix carbons from RUBP and carbon dioxide into usable energy. It then produces G3B, which can be assembled to make glucose, or other sugars. The end product which are carbohydrates make up the following formula; C6 H12 O6. Once these sugar molecules are being produced, photosynthesis has occurred. Once this process happens, the
