We need Oxygen for making Energy
Posted in 2013
Take a deep breath in and gently exhale. Every day, all day and all night, our lungs inhale and exhale air. Although calming, the goal of this process is to bring oxygen into the body. But ,why do we really need oxygen? Most students say to breathe, but this isn't quite accurate. We breathe to get oxygen, not the other way around. As it turns out, oxygen is the essential ingredient for making energy in a process called cellular respiration.
Cellular respiration is the process cells use to make energy. Our body cells need oxygen to do this process, although other organisms, like yeast or bacteria, don't always need it. They have other ways of making energy. But since the focus of this particular lesson is on the role of oxygen, we'll stick with animal cells, like the ones in our body.
All body cells engage in cellular respiration. They use oxygen and glucose, a sugar found in the foods we eat and convert them to ATP (adenosine triphosphate), or cellular energy, and carbon dioxide. Although this process can be represented by a single equation, there are actually many small steps that take place before we actually use oxygen to get ATP. Let's examine each of the three main steps in detail next.
My advise
1.... Cellular respiration has three main steps: glycolysis, the citric acid cycle, and oxidative phosphorylation, where oxygen is used.
a.... Glycolysis is the first step in cellular respiration, and it occurs in the main compartment of the cell: the cytoplasm. Cells let glucose in from the blood--the glucose comes from the food we eat. Next, cells convert glucose through several different compounds to make two ATP molecules and a molecule called pyruvate. A compound called NADH (nicotinamide adenine dinucleotide + hydrogen) is also created. This molecule stores electrons harvested from the glucose, which will be used later to create a larger amount of ATP.
b.... Citric Acid Cycle::Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water.
The name we'll primarily use here, the citric acid cycle, refers to the first molecule that forms during the cycle's reactions—citrate, or, in its protonated form, citric acid. However, you may also hear this series of reactions called the tricarboxylic acid (TCA) cycle, for the three carboxyl groups on its first two intermediates, or the Krebs cycle, after its discoverer, Hans Krebs.
c... Oxydative Phosphorylation::Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers. This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms
2... The human body is about two-thirds oxygen. In the human body, the oxygen is absorbed by the blood stream in the lungs, being then transported to the cells where an elaborated change process takes place. Oxygen plays a vital role in the breathing processes and in the metabolism of the living organisms.
3.... In the human body, the oxygen is absorbed by the blood stream in the lungs, being then transported to the cells where an elaborated change process takes place.
4... Oxygen plays a vital role in the breathing processes and in the metabolism of the living organisms.
5.... Probably, the only living cells that do not need oxygen are some anaerobic bacteria that obtain energy from other metabolic processes.
6.. The products are carbon dioxide and water (exhaled air has a relative humidity of 100%), which are eliminated by the human body through the lungs.
7... Appropriate levels of oxygen are vital to support cell respiration. Oxygen plays an important role in the energy metabolism of living organisms.
8... The living cell is the site of tremendous biochemical activity called metabolism. This is the process of chemical and physical change which goes on continually in the human body: build-up of new tissue, replacement of old tissue, conversion of food to energy, disposal of waste materials, reproduction - all the activities that we characterize as "life."
9... I explained you the important oxygen for body.
10.. If you are pregnant your child body cells of his brain, heart and all other parts need sufficient oxygen to develop properly. If oxygen is not sufficient to form the above he may be mentally or physically defective.
11.. The oxygen levels in your body is depend on your food. So follow healthy food to increase the levels oxygen in your body so that your child's body will develop properly.
