of three phosphate groups to adenine‚ hence the name adenosine tri-phosphate. The bonds holding these three phosphates are known to be highly energetic. Two of the phosphates are easily broken down to release energy and are added in a covalent bond during processes like respiration. ATP is the source for driving active transport and reactions like cellular respiration and photosynthesis. ATP is broken down by hydrolysis. This results in adenosine diphosphate and an inorganic phosphate. Along with this

-endocytosis -exocytosis -reproduction 1. You hear someone mention the molecule “AMP.” Based on what you learned about the structure of ATP and the way in which energy is released‚ what do you think AMP stands for and how do you think it would be created? Adenosine monophosphate. It can be produced during ATP synthesis by the enzyme adenylate kinase by combining two ADP molecules: 2 ADP → ATP + AMP. 2. Explain how the recycling of ATP helped save Mauro Prosperi. Why is the ability to recycle this molecule

biological molecules. ATP‚ which stands for adenosine tri-phosphate‚ is an energy rich compound having 3 phosphate group attached to adenine (nitrogen base)‚ called adenosine. Of the 3 phosphate groups‚ the terminal one has a weak linkage. This phosphate group can break spontaneously whenever ATP forms a complex with an enzyme. The breaking up of this bond releases chemical energy causing an immediate shift in the bond energy giving rise to ADP which is adenosine di-phosphate. This eventually leads to

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0

Protists‚ Fungi‚ and Plant cells use Cellular Respiration to produce the energy they need. In the process of Cellular Respiration‚ an organism’s cell will transform molucles such as starch or glucose into a form of cellular energy known as Adenosine Triphosphate(ATP). There are two ways cellular resperation can occur‚ Anarobic and Aerobic. Aerobic Respiration is the most productive form of cellular resperation. In Aerobic resperation‚ cells need oxygen to breakdown glucose. The cell does so through

Field event that uses various energy systems and muscles. The three energy systems used within all sports include: • ATP – PC System (Anaerobic System): This system works by breaking down food energies (stored in the cells) to produce energy and Adenosine Diphosphate (ADP). From here Phosphate Creatine (found in muscles)‚ a chemical compound‚ combines with ADP to produce more ATP. This system is used best for high intense events using large bursts of energy. • Lactic Acid System (Anaerobic System):
