Metabolic Muscular And Nervous Systems - 1,731 words
The immediate source of energy for muscular contraction is the high-energy phosphate compound called adenosine triphosphate (ATP). Although ATP is not the only energy-carrying molecule in the cell, it is the most important one, and without sufficient amounts of ATP most cells die quickly. The three main parts of an ATP molecule are: an adenine portion, a ribose portion, and three phosphates linked together. The formation of ATP occurs by combining adenosine diphosphate (ADP) and inorganic phosphate (Pi). This formation requires a large amount of energy to and it is called a high-energy bond. In order for a muscle to contract, the enzyme ATPase breaks the ATP bond and releases energy which is ...

The Fight For Creatine - 1,254 words
Creatine is an amino acid that is produced in the pancreas, liver, and kidneys. The natural creatine that is produced in the body replenishes adenosine triphosphate, which fuels muscle use. Creatine helps to add in extra repetitions during a lifting program. When adding in extra repetitions there are better chances of building muscle bulk. Many people feel creatine should be banned just like anabolic steroids because of long-term side effects. However, creatine is not as dangerous as some think and it should not be banned. Creatine is not only produced naturally but can also be bought as a supplement. Whether you buy it in powder or pill form it seems to have the same effect. Within the past ...

Creatine Research - 804 words
What is it and where does it come from? Simply put, creatine monohydrate is the most popular and effective bodybuilding supplement on the market. Everyone consistently using creatine is making gains in lean mass. There is one good reason why three out of four of the '96 summer Olympic medallists used creatine: it works and it works well. A French scientist first discovered creatine in 1832, but it was not until 1923 that scientists discovered that over 95% of creatine is stored in muscle tissue. The first published report of creatine having bodybuilding effects was The Journal of Biological Chemistry in, get this, 1926! Although weve known about creatine for quite some time, the first real u ...

Snakes Motabolism - 1,421 words
Eating, or ingesting food, is one of the main characteristics of the animal kingdom. Most of these animals metabolize their food at a rapid passe. But the metabolism of a snake is much slower then many other animals. This is due to one major factor. That is the temperature in which their bodies are. The metabolism works the same as other animals. It is just slower in a snake. The metabolism needs to be slower since the snake doesn?t eat very often. This paper will prove that a snakes metabolism is slow because of 4 different reasons: A. behavior B. evolution C. temperature D. lifestyle. Most animals (including humans) eat at least once a day. If we go longer then about a week we could die of ...

Creatine - 869 words
In today's society, a lot of emphasis is placed on how you look. Almost everybody wants that "perfect body". But with all the things people have to do, not many are willing to put in the time to get it. So there must be an easy way to get it. Right? Not too long ago people steroids. They injected horse testosterone into their veins to increase the amount of muscle mass produced from lifting. But after a while, some professional athletes and high profile people started showing the side effects that are associated with them. For example, Lyle Alzado, a popular star in the NFL, developed a brain tumor and died. This scared a lot of people and the recreational uses of steroids decreased. With th ...

The Biochemistry Of Human Energy Systems - 1,615 words
With the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e.g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate System The Glycolytic or Lactic Acid system The Oxidative system (The Krebs cycle, Citric Acid Cycle or Tricarboxylic Acid Cycle) The first too are ANAEROBIC, the third is AEROBIC. I.Creatine Phosphate ...

Mitochondria's Evolution From The Chloroplast - 651 words
I discovered that mitochondria evolved from the chloroplast (Audersirk p. 369). The endosymbotic hypothesis championed most forcefull by Lynn Margulis of the University of Massachusetts, propose that cells acquired the precursors of mitochondria and chloroplast by engulfing certain types of bacteria. This happens by the aerobe bacteria that absorbs those molecules and used energy oxygen to complete their metabolism. By gaining a high range of energy, using large food resources, great amount of energy leak out a ATP and right back into the host of cytoplasm that is how mitochondria came about. The role of the mitochondria in our are bodies is to process oxygen, convert fatty acids. Carbohydra ...

Photosynthesis - Changing Carbon Dioxide And Water To Sugars - 631 words
6H2O + 6CO2 ----------> C6H12O6+ 6O2 Six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen Photosynthesis is the process that green plants and certain other organisms use to change carbon dioxide and water into glucose (sugar) using the suns energy. Photosynthesis provides the basic energy source for practically all living organisms. A very important byproduct of photosynthesis is oxygen, which we cant live without. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are major sugar factories, producing millions of new glucose molecules per second. Plants use the glucose, a carbohydr ...

What Are The Major Components Of Biological Membranes And How Do They - 1,279 words
... that span the membrane. Class 5. Lipid Anchored--------- These proteins undergo substitution with the carbohydrate groups of glycolipids, therefore binding covalently with the lipid. This classification is not definitive in including all proteins, since there may well be other examples that span the membrane with different numbers of anchor chains. The structure of proteins varies greatly. The first factor affecting structure is the proteins function, but equally important is the proteins location, as shown above. Those proteins that span the membrane have regions of hydrophobic amino acids arranged in alpha-helices that act as anchors. The alpha-helix allows maximum Hydrogen bonding, an ...
