1) Discuss the three energy systems that are responsible for the production of ATP. Adenosine triphosphate (ATP) is the immediately usable form of chemical energy use for muscular activity. It is stored in most cells‚ especially muscle cells. Other forms of chemical energy‚ such as that available from foods we eat must be transforming into ATP before they can be utilized by muscle cells . Human body cells generated ATP by three methods which are: I. ATP-PC system II. Glycolytic system

Briefly explain the meaning of‚ and reasons for‚ strict liability. For strict liability offences it can be said that the prosecution does not have to prove the existence of mens rea for one or more of the elements of the actus reus of the offence. It is often said that no mens rea is needed for strict liability offences. This is probably an over simplification. A more complete answer would be that the prosecution does not have to prove the existence of mens rea for one or more of the elements of

Lab: Energy Stored in Food Background Questions (5 points each = 10 points): 1. What happens to the molecules of the food that we eat during digestion? 2. What type of metabolism is this? Background information: In this lab we will attempt to set a variety of different types of food on fire and capture the heat energy that is given off. The heat energy from the burning comes form the energy stored in the chemical bonds of the food. The more energy in the bonds‚ the more heat the food will

List the three roles of ATP in muscle contraction: 1.Energize the power stroke of the myosin cross bridge. 2.Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3.Energizing the calcium ion pump 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called Write the end products of this process: ATP (+ H2O) ______ADP___________ 3. Rebuilding ADP into ATP with a new source of energy is carried out by a process

ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi)‚ and needs energy. The overall reaction sequence is: ADP + Pi → ATP‚ where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium or H+‚ moving down an electrochemical

Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20

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

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
