The Aereobic Cellular Respiration Process

The next part of out project was respiration reactions. This happens in three parts. The first stage of cellular respiration is glycolysis. It takes place in the cytosol of the cytoplasm. The next stage in cellular respirations is the krebs cycle. Electron transport is the final stage of aerobic respiration. Glycolysis is used to break down 1 glucose molecule and produce 2 pyruvate molecules. The first part needs energy in order to take place. It splits glucose, and uses up 2 ATP molecules. If the concentration of pyruvate kinase is high enough, the second half of glycolysis can proceed. In the second half energy releases and 4 molecules of ATP and 2 NADH are released. Glycolysis has a net gain of 2 ATP molecules and 2 NADH. The krebs cycle starts with by combining a two-carbon with a four-carbon

In contrast, there are four metabolic stages happened in cellular respiration, which are the glycolysis, the citric acid cycle, and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm, in which catabolism is begun by breaking down glucose into two molecules of pyruvate. Two molecules of ATP are produced too. Some of they either enter the citric acid cycle (Krebs cycle) or the electron transport chain, or go into lactic acid cycle if there is not enough oxygen, which produces lactic acid. The citric acid cycle occurs in the mitochondrial matrix, which completes the breakdown of glucose by oxidizing a derivative of pyruvate into carbon dioxide. The citric acid cycle produced some more ATPs and other molecules called NADPH and FADPH. After this, electrons are passed to the electron transport chain through

Respiration consists of a complicated series of chemical reactions. The first step of cellar respiration, called glycolysis, takes place in the cytoplasm. The two main components are oxygen and

In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP.

To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2.

The acetyl group from pyruvate is oxidised in a series of nine reactions; the citric acid cycle. Also known as the Krebs cycle, it is the second stage of cellular respiration. Cellular respiration is a 3 stage process where organic fuel molecules are broken down, in the presence of oxygen, to harvest energy. These reactions occur in the mitochondrial matrix.

Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a

The first part of cellular respiration is glycolysis where energy is spent to break a glucose molecule down into two pyruvate molecules. A glucose molecule comes from your food and has 6 carbons on it. Glycolysis partially breaks

When cellular respiration is in process, hydrogen atoms are removed from glucose and transferred to oxygen atoms that form CO2 and H2O. A major process of cellular respiration is Glycolysis, which occurs in the cytoplasm just outside of the mitochondria. Glycolysis is the process by which glucose is broken down into two pyruvate molecules. Energy is used to release glucose, which gains 2 ATP. Oxidation follows which produces NADH. . (Mader, 2009)

The first step of cellular respiration is glycolysis (does not involve oxygen), which takes place in the cytoplasm of the mitochondria and it breaks glucose down

After completing the glycolysis stage, the two molecules of pyruvate acid that remains must be converted over so that you can start the Citric Acid Cycle. First the pyruvate must oxidize or reduce NAD+ to NADH where it will lose one of its carbons forming CO2 (carbon dioxide). Then each of the acetic acids will attach to a molecule called coenzyme A.

Glycolysis is followed by the Krebs cycle, however, this stage does require oxygen and takes place in the mitochondria. During the Krebs cycle, pyuvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. This begins when pyruvic acid produced by glycolysis enters the mitochondria. As the cycle continues, citric acid is broken down into a 4-carbon molecule and more carbon dioxide is released. Then, high-energy electrons are passed to electron carriers and taken to the electron transport chain. All this produces 2 ATP, 6 NADH, 2 FADH, and 4 CO2 molecules.

Next up is the Krebs cycle, which simply picks up where glycolysis left off. The Krebs cycle, or otherwise referred to as, the Citric Acid cycle, or the TCA Cycle, is extremely pertinent in cellular respiration. In fact, without this process, respiration could not be possible. Reason being, is the Krebs cycle takes the pyruvate molecules that were present in glycolysis in order to create high energy molecules necessary for the electron transport chain (ETC) which follows soon after. One of the interesting things about cell respiration is that it is part of an essentially universal "toolkit" that characterizes all of life, at least for life involving eukaryotic

Most of the reactions involved in the process are possible because of the redox reaction of NAD, an electron carrier

There are three important steps in cellular respiration, those are Glycolysis, Krebs cycle and Electron transport chain(ETC). The breakdown of glucose is called Glycolysis (Glycol = Glucose + Lysis = breakdown), it occurs in the cytoplasm and is the preliminary step in Glucose breakdown or respiration. It is an anaerobic process which means it
