the process of digestion

the equation. ATP, Adenosine Triphosphate, is the major source of energy in the human body. ATP plays a major factor in fueling our bodies by providing and storing energy. A normal ATP molecule has a strong bond called a phosphodiester bond, which stores energy that only releases when the body needs it (Ballard, 2003). The structure of the ATP molecule is very exclusive; because it has an oxygen molecule that is connected to three phosphorous groups, hint the name triphosphate. When one phosphate...

Anatomy cells and chemistry

oxydation reactions is used to form adenosine triphosphate ( ATP ), the Energy currency of the cell. 5. Name the two initials steps in glycolysis. The initial steps are the additions of two phospates to the glucose molecule at the expense of two molecules of ATP. 6. What are the three molecules that results? The three molecules that result are a 6 carbon sugar diphosphate molecule and 2 low energy adenosine diphosphate molecules. 7. What then occurs...

muscle fatigue

gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down, a phosphate molecule is broken off, reducing the phosphate molecules, from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue, the ATP has to rebuild from ADP and p (ADP+P+= ATP). As this occurs, more energy is released and so more energy is...

Energy Systems - ATP/CE, Lactic Acid & Aerobic

Energy Systems The ATP – CP system is primarily used for short duration exercises (about ten to twelve seconds) which involve a high intensity or explosive movements. Energy is stored within the chemical bonds between the Adenosine and the three phosphate molecules. Water is added in the chemical reaction, causing one of the bonds to break, which releases one molecule of energy from the phosphate. This molecule is used for the muscle contraction. The ATP then turns into ADP as it’s lost a phosphate...

Mitochondria: Cellular Respiration and Inner Membrane

Mitochondria Mitochondria are responsible for energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP), which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy, such as the flagellum. The role of the mitochondria is very important in respiration. In the presence...

Plasma Membrane

process is called active transport. Proteins take an active role in this process by regulating and controlling the transport of the molecules. In combination with proteins, energy is needed for the transport. An energy-carrier molecule called adenosine triphosphate (ATP) is binded to a transport protein, which enables it to carry the calcium ion across the membrane. Other active-transport proteins are used as pumps to help move the molecules against the concentration gradient. Sometimes a particle is...

Lab Report/Mealworms

is the intake of oxygen and energy in the form of glucose, and the cells ability to break it down into carbon dioxide, water, and energy required for the body to function. More scientifically, it is a three-step pathway that produces ATP (adenosine triphosphate.) The three stages of cellular respiration are: glycolysis, the citric acid cycle, and electron transport. Ethanol is a volatile, colorless liquid and is considered a psychoactive drug. Ethanol is generally known to have depressant effects...
