...Respiration Introduction Respiration is the processes through which human beings obtain energy from food. This process takes place in the mitochondria, which are cellular organelles located in the cytoplasm. There are two forms of respiration; aerobic and anaerobic respiration. For aerobic respiration to take place, oxygen must be present to facilitate this process. This fact explains the reason why human ventilate. On the other hand, anaerobic respiration only occurs when there is the absence or reduced amount of oxygen in the cells (Starr & McMillan 2012, p.55).

Anaerobic metabolism is more energy efficient because it helps in consuming the less useful carbon dioxide gas from the atmosphere. Anaerobic respiration can cause suffocation 3. Two ATP are produced at glycolysis stage a process known as substrate-level phosphorylation 4. When fermentation occurs in a sealed container, it means that there is no supply of oxygen and the process will be anaerobic.

This process involves glycolysis where the plant breaks down the glucose into two molecules pyruvate and again, an energy is released in the form of ATP. This process does not require oxygen and such called anaerobic respiration. In the next step of respiration, these pyruvate molecules are rearranged in a cycle and in the process produce carbon dioxide where electrons are pulled off and passed and generate ATP for the plant to use for it to grow called aerobic respiration (UCSB, nd). 2.

The anaerobic respiration is not a viable option for organisms to respire as it restricts the generation of FAD+ and NAD+ and may result in halting the whole process of respiration. However, for a limited time the pyruvate may accept electrons from NADH and thus form lactic acid but respiration can’t be continued for a long time in organisms (Starr 85).

...Anaerobic Metabolism & Acid base balance All cells are required to generate energy for survival, be it a eukaryotic or prokaryotic cell. The process involved in the production of cellular energy was defined by Hans A. Krebs in the year 1937. He proposed that the production of cellular energy is association with a particular metabolic pathway in the cells. This is called the Krebs cycle or the citric acid cycle which defines the oxidation of carbohydrates in animal tissues. Consequent to this finding it was later found that the acetyl derivation (a compound produced during fat degradation) has identical properties to the compound produced when... The Krebs cycle and its relationship to Aerobic and...

...respiration and mountain sickness Highaltitude: effects on respiration and mountain sickness Before understanding the effects of high altitude on respiration and mountain sickness, it is essential to first understand what high altitude means. "Altitude is defined on the following scale High (8,000 - 12,000 feet [2,438 - 3,658 meters]), Very High (12,000 - 18,000 feet [3,658 - 5,487 meters]), and Extremely High (18,000+ feet [5,500+ meters])" (Curtis, 1995). As a person goes up a higher altitude, both barometric pressure and the partial pressure of oxygen decrease. According to Ward et al (1995), barometric pressure falls... (Smith 2005). Although endurance activities are significantly...

...anaerobic respiration, when the metabolism of pyruvate was reduced. The end product of this alteration is lactic acid, and will trigger a metabolic acidosis leading to death (Black and Hawks, 2005). Moreover, since the liver metabolizes lactate, hepatic failure will further aggravate the elevation of serum lactate. The high mortality rate of lactic acidosis, which is above 50% (Gutierrez & Wulf, 1996), contributes to the high mortality rate in septic shock secondary to lactic acidosis. As the value of serum lactate reflects the degree of cellular damage... ?Septic Shock Introduction Septic shock is a life-threatening, debilitating medical emergency wherein the toxins released by microorganisms produces...

...Respiration and circulation Introduction Respiration and circulation are two different aspects, but their functionality involves the provision of oxygen and elimination of carbon dioxide in the body. During respiration, energy is released by oxygen from food. The process also involves removal of carbon dioxide (CO2) as a by-product. Circulation is movement of blood through the blood vessels in the body to and from the heart. Both components are related in that CO2 is a waste product that has to be eliminated from the body through the process of respiration. Other waste products such as dead blood cells are absorbed to the...
