Adenosine triphosphate

aerobic endurance. Physical activity is fueled by three different sources of energy depending on necessity; ATP Production, The glycolytic system, The oxidative system.  Adenosine triphosphate (ATP) is the molecule that stores and transports chemical energy within cells for cellular functions. When ATP breaks into ADP (adenosine diphosphate) and Pi (phosphate), energy is released. During exercise the body requires ATP sources for muscle contraction in which ATP binds to myosin,

earth were microbes. Aerobic cellular respiration and oxygenic photosynthesis both play a big role in our evolution. Cellular respiration is a process that mostly takes place in the mitochondria where cells break down food and turn in it into adenosine triphosphate(ATP), or in more simpler terms, energy for the cell. Although cellular respiration can do either anaerobic or aerobic cellular respiration processes, it is usually used to describe aerobic cellular respiration because it actually was created

An Overview of Thermodynamics and Bioenergetics with respect to Biochemistry What is Thermodynamics? It is that field of physical science which describes the relationship between heat and other forms of mechanical, chemical and electrical energy. It basically deals with the basics of heat to the kinetic theories to the laws of thermodynamics. Thermodynamics is widely used by biochemists to understand chemical reactions and processes taking place in an organism. Thermodynamics is based to three laws

Respiration is the release of energy. All cells in our bodies respire to get energy. This energy can be used to release heat to keep our bodies at a regular temperature or make ATP (Adenosine triphosphate).

the purpose of chemical reaction (Krebs cycle) that require oxygen to produce ATP (Freudenrich, 2008). This is due to the contractions and extension of muscle and respiration will require a large amount of energy that stored in the form of adenosine triphosphate molecules (ATP), for the neurons to send impulses to the muscle cells, as well as for the chemical reaction of muscle cells itself. In this situation, the sequence of chemical reaction will happen continuously. ATP will be produced and used

referred to as the light-independent reactions (Damon, 2007). The light-independent reactions predominantly involve photosynthetic pigments (including chlorophyll) absorbing light energy and undergoing a conversion into chemical energy known as Adenosine Triphosphate (ATP). Also, light energy is utilised by the plant to undergo

supply of O2 has depleted (or never existed initially). Aerobic respiration utilises the resulting product of glycolysis (which is pyruvate) in the Krebs cycle, also known as citric acid cycle, to create much more energy in the form of ATP (Adenosine Triphosphate) . The equation for aerobic

The Krebs cycle also known as the Citric Acid cycle, is the second part of the three steps in which cellular respiration happens. The Krebs cycle was discovered and named after Hans Krebs, a German scientist. The Krebs cycle takes place in the mitochondrial matrix of the cell, occurring between glycolysis, which breaks down glucose turning into pyruvate, and oxidative phosphorylation, which is what creates ATP. This is processes where the body harvests energy from the food we consume. The Krebs cycle

Photosynthesis and Solar cells In order for humans to live, as well as all living organisms, photosynthesis used by plants to create solar energy is essential. The way cells are created and regenerated is fascinating and we are still making new discoveries each and every day. A solar cell converts light energy from the sun directly into electricity. Plant cells contains chloroplasts and absorbs light energy from the Sun. Plant growth and development are driven by continuous generation of new

respiration occur in the mitochondria, which the peas contain, through a series of reactions. Since all cells need energy, the primary source of cellular energy is carbohydrate, which are broken down into glucose to release energy, stored in adenosine triphosphate (ATP), from the bonds. Plants obtain glucose through photosynthesis while animals obtain it through consuming food. Cellular respiration can be summarized through the equation: C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + 36 ATP.
