photosynthesis ceased there would be little food or organic matter on Earth. Most organisms would disappear‚ and in time Earth’s atmosphere would become nearly devoid of oxygen. b. ATP is formed by the addition of a phosphate group to a molecule of adenosine diphosphate (ADP). Courtney S. 4th Period

for any muscle contraction to occur‚ obviously when exercising at a high level like sprinting more ATP are needed to supply the energy‚ but because stores only last for up to 4 seconds the body needs a system that can re-synthesise adenosine die phosphate in to Adenosine tri phosphate very quickly when an individual starts to exercise. Carbohydrates‚ fats and proteins are digested to provide a source of energy. Carbohydrates are usually in the short term and fats are mainly used in the long term‚ protein

temporary stores of energy. They can be broken down more readily than other‚ more complex molecules for a quick source of usable energy. The process by which usable energy is released from carbohydrates and captured in the bonds of ATP (adenosine triphosphate) for use by cells is known as cellular respiration. Many metabolic processes in cells require energy derived from ATP‚ so ATP is considered to be the “universal energy currency” of the cell. All energy pathways can be traced back to sunlight

PLASTIDS Plastids are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants

Cellular respiration is the process that mainly important in our daily life and supply energy to your body. The main purpose is to turn food into usable chemical energy called ATP. Your body can use ATP as a source of energy to function. Cellular respiration is also the procedure by which cells in plants and creatures separate sugar and transform it into energy‚ which is then used to perform work at the cell level. The reason for cell breath is straightforward: it gives cells the vitality they have

respiration is taking place. This is respiration involving the consumption of oxygen gas‚ producing carbon dioxide and water‚ as shown below. C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36ATP This process allows energy to be produced in the form of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported into the mitochondrial matrix via active transport. Numerous reactions‚ catalyzed by a multi enzyme complex then occur‚ where the pyruvate

Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether

ABSTRACT: Availability‚ low price‚ and high degree of reduction have made glycerol a highly attractive and exploited carbon source for the production of fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis
