- While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
- Kelly is walking to the park with her mother. Kelly loves plants.
- A campfire breaks chemical bonds in wood, releasing stored energy as light and heat; respiration breaks chemical bonds in glucose, releasing stored energy and transferring some to ATP and some energy is lost as heat.
- When she got to the park, the first thing she did was wonder how the plants were able to grow. Kelly then remembered that the plants get carbon dioxide from the air. Water from the environment and light from the sun. The carbon cycle is the pathway through which carbon is recycled in the biosphere. During respiration, glucose molecules are decomposed into simple carbon dioxide and water molecules. Also, heat is used in breaking up glucose to release energy. Hence, respiration is a thermal decomposition reaction, or more specifically, an exothermic reaction.
- To dig deeper into how photosynthesis works, Kelly was able to remember that light-independent reaction and the Calvin Cycle. The light-dependent reaction is part of photosynthesis. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in ATP.
- Plants take in CO2 from the air and water from the ground to make ATP energy in order to survive.
- What they do is both of them take place in different parts of the plant but they help photosynthesis to happen since the light-dependent reaction takes place in the thylakoid membrane and helps to make ATP and NADPH.
- As Kelly was thinking about inputs and outputs of cellular respiration, she noticed that cellular respiration is also needed for plants because it helps them use that food from photosynthesis to create usable energy. Cellular respiration inputs glucose and carbon and produces carbon dioxide and water.
- Kelly wants to tell you guys more about cellular respiration and the different steps that included glycolysis, the Kerbs Cycle, and the electron transport chain because they all play the part in giving oxygen to the air. The hydrosphere and the atmosphere overlap because there is always water in the atmosphere.
