Metabolism, which encompasses a vital sequence of biochemical reactions, is essential for the survival of all living organisms. During activities such as marathon running, the body relies on its fat and carbohydrate stores to generate Adenosine Triphosphate (ATP) as an energy source. ATP plays a significant role in various biological processes, including movement and molecule formation.

An athlete can utilize anaerobic and aerobic pathways to enhance muscle energy during a marathon. However, these pathways are more significant at different stages of the race. Initially, the body breaks down fats as the primary source of energy. Tissues such as the heart, liver, and resting skeletal muscles prefer using fats for fuel while reserving glycogen stores for emergencies or high-intensity activities that require immediate energy.

Athletes accumulate lipids, or fats, in their adipose tissu


e. This storage method has a greater energy capacity per weight unit than carbohydrates. The stored lipids exist as triglycerides and can be affected by low blood glucose levels in athletes. This effect prompts the secretion of hormones such as glucagon and adrenaline, which activate the enzyme lipase and induce the release of fatty acids from adipose tissues.

The enzyme decomposes triglycerides into fatty acids and glycerol, while serum albumin transports the fatty acids in the bloodstream to adipose tissue and eventually muscle cells for oxidation. At the 45-minute mark of the marathon, there will be an elaborate discussion on Ÿ-axolotl, a specific process of fatty acid oxidation. After 5 minutes, the athlete will begin utilizing anaerobic pathways to acquire energy. Carbohydrates are mainly present in liver and muscle tissues, where they can be extracted and stabilized to serve as fuel.

TAP originating from carbohydrates is a faster energy source for muscles compared to fats. During the glaciology thaw, this enables athletes to sprint right at the beginning of a race. However, this rapid energy rate can only support the body for short durations. Consequently, the abundant fat stores will gradually be oxidized and become the primary source of energy for the rest of the marathon. At the start of the race, the anaerobic pathways involve Glycoside followed by lactic acid fermentation, with glucose as the initial product of Glycoside.

The body's energy status regulates the activity of Glycoside. If there is an accumulation of TAP, Glycoside will be inhibited. On the other hand, glycogen stored in the liver is converted into glucose-1-phosphate by the enzyme glycogen prophylaxes. However, glucose-1-phosphate still contains a, 1-4 linkages that cannot be broken down by glycogen phosphoresce. Therefore, an additional conversion to glucose-6-phosphate is necessary, facilitated by the enzyme phosphorescently which can break the a, 1-6 linkages.

In conclusion, glucose-6-phosphate can directly enter the glaciology pathway. The initial step of Glycoside involves a glucose molecule with a 6-carbon backbone that splits into two molecules of private with a 3-carbon backbone. This glaciology pathway takes place within cells and consists of 10 reactions, with 5 considered as the preparatory phase and the remaining 5 as the pay off phase. The preparatory phase is energy-consuming and relies on TAP for the reactions to occur.

One crucial reaction in Glycoside is the conversion of glucose to glucose-6-phosphate, which is facilitated by a physiotherapist. This reaction involves the transfer of hydrolysis from TAP, providing energy and ensuring irreversibility. The negative change in free energy

permits a spontaneous reaction within cells. In the preparatory phase, 2 molecules of TAP are consumed at the expense of energy. However, in the pay off phase, 4 molecules of TAP are synthesized and electrons are transferred through 2 hydride ions to 2 molecules of AND+.

Hence, the glaciology pathway alone leads to a net gain of 2 TAP. In the glaciology pathway, since oxygen cannot be supplied quickly enough for aerobic respiration, the athlete experiences lactic acid fermentation. In this process, the private formed from the glaciology pathway is converted to lactate with the help of the enzyme lactate dehydrogenate, while the NADIA is oxidized to AND+.

The product AND+ reenters the glaciology pathway to generate 2 TAP. This process of lactic acid fermentation yields 2 TAP per cycle, rapidly supplying a small amount of energy to the body. However, as lactic acid accumulates in the body, it eventually causes discomfort and soreness. After 45 minutes, fat metabolism resumes, similar to the start of the race.

The athlete's body will undergo the Ÿ-oxidation pathway to produce intermediates of the glaciology pathway, leading to the production of Acetylene-coca that can enter the CA. However, carnation transporters are needed for fatty acids to cross the plasma membrane. When fatty call-coca needs to move across the inner mitochondrial membrane into the mitochondrial matrix, it must combine with carnation to form fatty call-carnation in order to utilize the carnation transporters. This is necessary because fatty acids are insoluble in water and need assistance for entry into the mitochondrial matrix.

Once the fatty acyl-CoA molecule reaches the mitochondria, it undergoes a conversion to become fatty acyl-CoASH in preparation for

?-oxidation. This process includes four reactions that eliminate two carbons from the carboxylic end of the chain, resulting in the creation of acetyl-CoA. Simultaneously, FADH2 and NADH are produced as part of this conversion. Despite each cycle producing two ATP through FADH2 and NADH synthesis, fatty acid oxidation occurs within the mitochondrial matrix and involves eight reactions. Following this, the acetyl-CoA combines with oxaloacetate upon entering the citric acid cycle to form citrate.

In the following reactions, two molecules of carbon monoxide (CO) are removed, along with four pairs of electrons, resulting in the formation of one molecule of Guanidine troposphere (GET). In the final reaction of CA, which involves the oxidation of emulate to collocate, the regenerated collocate can react with another molecule of Acetylene-coca, completing the cycle. Despite being unfavorable, this reaction still occurs due to the low concentration of collocate.

In summary, CA is a significant contributor to the production of NADIA through the complete oxidation of Acetylene-coca. During this process, NADIA becomes an energy-carrying molecule that can enter the ETC and generate a majority of TAP. After following the CA pathway, NADIA combines with Villain Adenine Denunciative (FAD) and enters the ETC. This involves transferring electrons from these cofactors to flavorings and then to ubiquitous compounds, which eventually reduce oxygen to water. The ETC takes place in the inner mitochondrial membrane and consists of four enzyme complexes that facilitate electron transfers from NADIA or succinctness.

Among the 4 complexes, complex I, Ill, and IV have the ability to transport protons from the matrix to the intermediate space. This movement of protons creates a proton gradient, with a higher concentration of protons

in the intermediate space compared to the matrix. As a result, the proton gradient acts as a driving force for the protons to return to the matrix and establish an electron flow. Consequently, when the protons flow back into the matrix, the TAP synthesis facilitates the physiotherapist of ADAPT, leading to a total of 32 TAP per glucose molecule.

This text provides an overview of the metabolic pathways involved in a marathon. Initially, the athlete undergoes p-oxidation to utilize glycogen storage for quick activity within the first 5 minutes. The athlete then follows the glycolysis pathway and subsequent anaerobic respiration, which provides 2 TAP per glucose molecule but may lead to muscle discomfort due to lactic acid buildup. After 45 minutes, the athlete's fat oxidation becomes dominant again, resulting in a yield of 32 TAP.
