Essay Comparing And Contrasting Photosynthesis And Respiration

Inside the cytoplasm glucose molecules are broken down into smaller pieces and then release energy.

are complementary processes by which living things obtain needed substances.

Cellular respiration is a process in which water and carbon dioxide are produced through the break down of chemical bonds of glucose or the oxidizing of food molecules. Retrieved on June 18, 2010 from Palomar College: Chem Web. Metabolism, Cellular Respiration and Photosynthesis.

Energy is released during cellular respiration and is captured as Adenosine Triphosphate (ATP) and then utilized by different cell activities that consume energy.

During photosynthesis there is a two­stage process.

The first step is to capture the Sun’s energy, which occurs in the leaves and other green parts of the plant, and once there pigments start absorbing the light; while the same time it gets CO2 through the surrounding air, which enters the plant by going into the stomata.They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need.After everything has been captured the first thing that happens is that inside the chloroplasts, both water and CO2 undergo a complex series of chemical reactions which is powered by the energy from the Sun, which results as sugars(glucose) and oxygen.Considering all of this, why is this essential for life?Then it gets water through its roots into the plant itself.The second stage would be using the captured molecules, energy, and soil, to produce food.Just like photosynthesis, respiration requires a 2­step process.The first step occurs in the cytoplasm of the organism’s cells.
