The Reflection Of The Three Stages Of Cellular Respiration

Respiration is a complicated series of chemical reactions. The first step of cellular respiration, called glycolysis, takes place in the cytoplasm. The two largest segments are oxygen and glucose. Lungs take in the oxygen, and the glucose is taken in by eating food. The function of glycolysis is to split a glucose molecule into two molecules of pyruvate so that it is modest enough to fit into the mitochondria. A C6 or glucose molecules are taken in and split into two C3 molecules. C3 molecules called pyruvic acid (PA) molecules. Glycolysis results in the manufacturing of two ATP’s, two pyruvic acid molecules, and one NADH. All of this is done without oxygen. The second step of cellular respiration is the oxidation of pyruvate, which takes place

Protons proceed back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transit chain, oxygen accepts electrons and takes up protons to form water.

Glycolysis can take place without oxygen in a process called fermentation. The other three phases of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative

However, while cellular respiration is concluded through animals (and some plants) by modifying food and organic molecules to energy, photosynthesis is the procedure of changing energy from light sources, especially the sun, into chemical energy for plants, algae, and some bacteria. Photosynthesis is a process that ensues within organelles called chloroplasts. These organelles can absorb light and are located inside of leaves. Within the leaf are tiny pores described as stomata, in which carbon dioxide can enter, and oxygen can exit, the reverse process that in which most animals breathe. Comparable to animals, the process of photosynthesis needs water, although rather than drained, water is absorbed through the plant's roots and carried up to the leaves. The stomata are perhaps the most critical piece to this process, as this is where CO2 enters and can be reserved, and where water and O2
