Energy, Metabolism, and Cells Photosynthesis is the process that pretty much every organism on earth needs, because of the nutrients produced which is needed in order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis, it takes the sun’s energy and chlorophyll found in chloroplasts in the green leaves of plants, to turn inorganic carbon dioxide into glucose (sugar) to make oxygen which we all need to live.
So, when animals eat the plants, and take the carbon in the sugars, inside their cells they take the energy from the food, this is cellular respiration, which takes oxygen (product of photosynthesis) and makes carbon dioxide (also used in photosynthesis) , it then gives energy by breaking down the food molecules, this is the link between the two. There are two types of cellular respiration; aerobic and anaerobic. Both use the same steps, where the sugar created during photosynthesis is broken down. (Audesirk, T., Audesirk, G., and Byers, B. (2008) A process known as glycol sis occurs. However they differ in that one uses oxygen and more energy and one uses less energy (or stored energy) and no oxygen. This biological molecule is used to store energy.
When the chlorophyll takes in the sunlight’s energy it then turns it into chemical energy, like glucose, simple sugars and ATP (Adenosine triphosphate), which is in all living cells.
In the absence of oxygen, the anaerobic cellular respiration occurs which is called fermentation.
In anaerobic respiration produces ethyl alcohol (Audesirk, et al, 2008, p.58). We use fermentation as a process in the making of various foods and wines. We use the alcohol and yeast to make certain foods and the process used is called fermentation.
