  • Process Of Photosynthesis
    415 words
    Process of Photosynthesis Photosynthesis is process by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the air in the presence of light. Green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis has f...
  • Free Energy
    517 words
    The second law of thermodynamics states that energy transitions are imperfect. No matter what, energy is lost. In machines an 75% loss of energy is considered average. In biological reactions there is usually a 60% loss. Since all reactions are constantly losing a percentage of the energy they give, it is necessary to have a constant intake of energy to make up for what is lost. This intake of energy helps life to remain ordered. If something disrupts that order, entropy begins to take effect. I...
  • Glucose For Later Use As Energy
    1,094 words
    The Chemistry of Carbohydrates The chemistry of carbohydrates most closely resembles that of alcohol, aldehyde, and ketone functional groups. As a result, the modern definition of a carbohydrate is that the compounds are polyhydroxy aldehydes or ketones. The chemistry of carbohydrates is complicated by the fact that there is a functional group (alcohol) on almost every carbon. In addition, the carbohydrate may exist in either a straight chain or a ring structure. Ring structures incorporate two ...
  • Alpha D Glucose And Beta L Fructose
    4,253 words
    Glucose is one of the most essential and plentiful carbohydrates found on Earth. It is very important and crucial for many life functions, and procedures. Glucose also known as a aldohexose is a monosaccharide with 6 carbons and an aldehyde group. It has many forms and isomers and each one of them has its own importance and function. Glucose is known to be the most important carbohydrates partially because of its effects on functions of life. Glucose is essential for many causes such as photosyn...
  • Reactions Transfer Electrons And Energy
    2,232 words
    By GERARD CHRETIEN BIOLOGY Cellular Pathways Several principles govern metabolic pathways in the cell: A. Complex chemical transformations in the cell do not occur in a single reaction, but in a number of small steps that are connected in a pathway. B. Each reaction is catalyzed by a specific enzyme. C. Metabolic pathways is catalyzed by a specific enzyme. D. Many metabolic pathways are compartmentalized, with certain steps occurring inside an organelle. E. Metabolic pathways in organisms are re...
  • 2 Atp Produced
    404 words
    Extracting energy from glucose Two different pathways are involved in the metabolism of glucose: one anaerobic and one aerobic. The anaerobic process occurs in the cytoplasm and is only moderately efficient. The aerobic cycle takes place in the mitochondria and is results in the greatest release of energy. As the name implies, though, it requires oxygen. Anaerobic metabolism Glucose in the bloodstream diffuses into the cytoplasm and is locked there by phosphorylation. A glucose molecule is then ...
  • Net Profit Of Two Atp Molecules
    2,297 words
    With the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e.g. ATP ADP + Pi There are three energy systems that do this; oThe Creatine Phosphate S...
  • Fat Stores In Adipose Tissues

    Absorptive And Postabsorptive States Absorptive And Postabsorptive States Essay, Research Paper Absorptive and Postabsorptive States The absorptive state is the time during and right after eating a meal. The absorptive state lasts for four hours, during and after each meal. During this state glucose is the most important energy fuel. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. Metabolites are transformed to fat if they are not used for anabo...
