ATP And Cellular Respiration

ATP is often referred to as the energy currency of life. The cells use a form of energy called ATP to power almost all activities, such as muscle contraction, protein construction, transportation of substrates, communication with other cells and activating heat control mechanisms. Adenosine Triphosphate (ATP), an energy-bearing molecule found in all living cells. Formation of nucleic acids, transmission of nerve impulses, muscle contraction, and many other energy-consuming reactions of metabolism are made possible by the energy in ATP molecules. The energy in ATP is obtained from the breakdown of foods.

Adenosine triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including active transport, respiration, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used.

Introduction: Cellular respiration and fermentation are used in cells to generate ATP. All cells in a living organism require energy or ATP to perform cellular tasks (Urry, Lisa A., et al. , pg. 162). Since energy can not be created (The first law of thermodynamics) just transformed, the cell must get its energy from an outside source (Urry, Lisa A., et al. , pg.162). “Totality of an organism’s chemical reactions is called metabolism” (Urry, Lisa A., et al., pg. 142). Cells get this energy through metabolic pathways, or metabolism. As it says in Campbell biology, “Metabolic pathways that release stored energy by breaking down complex molecules are called catabolic pathways” (Urry, Lisa A., et al. pg.

Cellular respiration and effects of pollutants and carbohydrates on its rate is determined . its purpose is to determine the importance of cellular respiration on the process of life. Respiration is process that take place in cell to convert the biochemical energy to ATP.

• With 6 ATPs being consumed and used, but only 2 ATPs being synthesized. 4 ATPs are being wasted and lost. Less ATP will be produced if the entire Cori cycle occurred and remained within that single cell.

Cellular respiration is creating ATP from ADP and a phosphate inorganic using the energy which was released from breaking apart glucose. The equation that summarizes this process is (ADP + Pi) + C6H12O6 +6O2 → 6H2O + 6CO2 + heat + (ATP). ATP is made up of a sugar ribose, 3 phosphate groups, and adenine. ATP is the energy used to complete processes in the body. ATP also has a very high potential energy because of its phosphate groups. Potential energy has to do with energy due to location. For example, a person on a diving board has a higher potential energy than a person already in the water. This is because the girl on the diving board has more potential to fall or convert the potential energy into kinetic energy by using her location to power her fall. The ATP has higher potential energy because its phosphate groups have oxygen ions. The negatively charged oxygen ions repel each other and do not want to be near to one another. Because of this, if the third phosphate group was to break off of the ATP molecule, an amount of energy would be released, lowering the potential energy. This is why ATP has such a high energy and is used for so many processes. The ATP would become ADP with a phosphate group becoming inorganic and would release energy.

There are three energy pathways. Each pathway has two identifiable exercises that utilizes each pathway.

ATP-PC - Adenosine triphosphate (ATP) is the usable form of chemical energy for muscular activity. It is stored in most cells, particularly in muscle cells. Other forms of chemical energy, such as that available from the foods we eat, must be transferred into ATP form before they can be utilized by the muscle cells.

All living cells require energy in order to proceed with cellular processes such as active transportation, and the synthesis of molecules. ATP (Adenine Tri-Phosphate) is a molecule, which provides energy in a form that cells can use for such cellular processes. Cellular

The amount of ATP in the cells stay constant when physical activities increase. In the lab, students are experimenting their pulse rate in beats/min through three physical activities. An observation that is noticed is how everyone breathed really hard when they are faking to jump rope in the third activity. In addition, the average pulse rate for the relaxation activity is 60, the moderate activity is 121, and the intense activity is 155. As displayed in figure 1, the trend of the first bar and second bar double as the intensity of the activity increases. When performing an intense activity, the body requires an abundance of oxygen to produce energy which is also ATP. That process is called cellular respiration which uses glucose and oxygen

ATP serves as a cellular signal in the body as the cells use ATP to help them regulate. If a cell has enough ATP, the ATP signals the cell to store nutrients when there is enough ATP. It acts as an on-off switch to control chemical reactions and to transmit messages. The shape of the protein chains that produce the building blocks and other structures are determined by weak chemical bonds which are simply broken and reconstructed. These chains can lengthen, shorten and change shape depending on the input or output of the energy from ATP. The changes the chains modify these shapes of the protein and its function, making it become either active or inactive. Furthermore, the energy from ATP is used to pump The transmembrane ions across the cell

Mitochondria are double membrane bound organelles that are essential for producing 95% of our cells energy in the form of ATP1. We have around a hundred to a thousand of these organelles present in each of our cells and they are unique to other organelles in that they contain their own DNA1. But why is this? And how has this benefited the cell in evolutionary terms? Mitochondria are most commonly thought of as the ‘power house’ of the cell due to ATP production being their main function however they have also evolved with many other abilities. I plan to focus how the mitochondria came about and how its structure and function have changed. As mitochondria have many functions I will be looking specifically into mitochondria’s roles in ATP production

The ATP / CP Energy system (more commonly known as the Adenosine Tri Phosphate) empowers the Skeletal muscle, for all movement. This energy system consists of Adenosine & three Phosphate groups. When this third Phosphate group brakes away, the energy is released & therefore ATP becomes ADP, Adenosine Di (2) Phosphate. To replenish & replace the limited stores of ATP & to continue to produce energy, food is broken down via a number of complex chemical reactions to add a phosphate group to ADP to produce ATP. With oxygen, this process is called Aerobic Metabolism, & without oxygen, anaerobic Metabolism. The human body will initially rely on the ATP accumulation in the body to produce energy for the first 3 – 4 seconds. After this point, the body
