My Lab on Cellular Respiration

Cell respiration, also known as oxidative metabolism, is important for converting biochemical energy from nutrients in living cells to useful energy called adenosine triphosphate (ATP). Without cellular respiration, organisms can not sustain life just because nutrients can not be metabolized during production. In this laboratory cell respiration was performed by measuring the amount of O2 consumed / used by placing a respirometer consisting of germinated pea and ungerminated pea in a room temperature bath and a low temperature bath.

The term cellular respiration refers to a biochemical pathway in which cells release energy from the chemical bonds of food molecules and provide energy to the basic process of life. All living cells must undergo cell respiration. You can do aerobic respiration in the presence of oxygen or anaerobic respiration. Procaryotes undergo cellular respiration in the cytoplasm or on the inner surface of cells. Here more emphasis will be placed on eukaryotic cells where mitochondria are the sites of most reactions. The energy currency of these cells is ATP, and one way to observe the results of cell respiration is as a production process for ATP.

Plant cells produce cellular respiration and produce ATP molecules after the production of sugar molecules by photosynthesis. Animals obtain food molecules from plants and other organisms, and then perform cell respiration to obtain ATP molecules. All organisms use these stored ATP molecules for their metabolic processes

Cellular respiration is a metabolic process that occurs in mitochondria of eukaryotic cells. In contrast to respiratory photosynthesis, photosynthesis uses light energy to make glucose molecules. Breathing catabolizes glucose and produces ATP. ATP is an energy molecule that is used to move most cellular functions. The general formula of respiration is C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + energy. When respiration occurs in the presence of oxygen, it is aerobic respiration. There are three processes of aerobic respiration: glycolysis, Krebs cycling, oxidative phosphorylation. When all three processes are completed, 36 net ATPs are generated.

Cellular respiration is a group of metabolic reactions and processes occurring in biological cells that convert biochemical energy from nutrients to adenosine triphosphate (ATP) and then release waste products. The reaction involved in breathing is a catabolic reaction that decomposes a macromolecule into smaller molecules and releases energy during this process, as weak "so-called high energy" bindings are replaced by stronger bonds in the product . Breathing is one of the important ways that cells release chemical energy to promote cellular activity. Cell respiration is thought to be an exothermic redox reaction that releases heat. All reactions occur in a series of biochemical steps, the majority of which are redox reactions themselves. Although cell respiration is technically a combustion reaction, it is clearly different from what happens in living cells, as a series of reactive energy is released slowly.
