Metabolic pathway

Chapter 6 You will discover many unexpected beneficial effects when you begin to fast. One thing fasting does is to make more of your energy available, so that your body can heal itself naturally. Fasting can be used as remedy for the way we often over indulge. Food is made to be enjoyed, but sometimes we overdo it. Too much food over a long period of time takes its toll on your body. Your body suffers if it is forced to handle more than what is comfortable and appropriate for it. When your body…

sensory division nerve fibers convey impulses to the Central Nervous System while the motor division carries impulses from CNS to effector organs, muscles, and glands (Marieb 2003). The neuron’s anatomy consists of the cell body (also known as the metabolic center of the cell) which contains the nucleus and abundant in nissl substance and neuro-fibrils. There are also the fiber…

With natural selection its major driving mechanism, evolution is the change over time in the makeup of genetics of a population. Supported by evidence from many scientific methods, Charles Darwin, in On the Origin of Species, asserts that inheritable variations occur in individuals in a population. In the process known as natural selection, due to competition for limited resources, individuals with more favorable characteristics or phenotypes are more likely to survive and better reproduce,…

Research Question Is the carbon dioxide emission rate per gram (ppm/s/g) of an outer onion (Allium cepa) layer, greater than the carbon dioxide emission rate per gram (ppm/s/g) of an inner layer? Scientific Context Cellular respiration is a catabolic pathway that breaks down complex molecules to more simple ones which release stored energy (World of Biology). The process of cellular respiration produces carbon dioxide (CO₂). It is powered by the oxygen that we take in as we breathe and CO₂ is…

the Rate of Photosynthesis of Elodea in the Aquarium Aim The aim of this experiment was to investigate the relation between the light intensity and photosynthesis rate of Elodea in an aquarium using a simulator. Background Photosynthesis is metabolic pathway in which plants use carbon dioxide and water to produce glucose by the aid of light energy from the sun. Light energy is usually absorbed by chlorophyll; a green pigment in plants. The equation of photosynthesis is as follows: Although…

Toothpickase Activity Lab Report By: Rohan Shah Michael Chan, Bravo Zayas Kimonas Valais, Ronan Murphy, Matthew Sultana, Orlando Santiago Teacher: Mrs. Istrico November 3rd, 2014 A Period Abstract: This report is a demonstration of different conditions an enzyme is exposed to and how the enzyme reacts in response. The conditions the enzyme was exposed to include: ideal conditions, the presence of a competitive substrate, denaturation for a short amount of time, and complete…

Discussion: Each test is a pertinent contribution to drawing an educated conclusion. After performing the gram staining and observing which unknown culture was gram positive, a catalase test was performed. The catalase test allows lab workers to differentiate Staphylococci and Streptococci genus. The test was performed only on the gram-positive culture. Bacteria that respire by the use of oxygen, otherwise known as aerobic respiration, produce enzyme or “catalase”. This protects the bacteria…

may also have dysregulation of the afferent signals, central nervous system integration, and efferent signals. Many of these factors are influenced by genetic predispositions in different populations. The occurrence of obesity and its pathogenesis as described above is influenced by both environmental and genetic components. In previous sections the environmental aspect was discussed, here the genetics behind obesity will be reviewed. Within the genetic component, there are degrees of…

whether it will live or die. The word “signals” in this context refers to nothing more than chemical molecules that are floating around the cells. In general, these signals bind to cell-surface receptors that activate several intracellular signaling pathways, so that the intracellular signals generated from different receptors will interact with one another in complex ways. Cell signaling affects virtually every aspect of cell structure and function. Cell signaling is also intimately involved…

How often has someone made the comment “He comes from a long line of alcoholics?” Perhaps you have even heard someone say, in a heated moment, “He’s a drunk, just like his father!” Most of us have heard about someone who grew up in an alcoholic home. We may have even witnessed the tragic and senseless episodes of drunkenness and its effects on the family. But does this automatically mean the offspring is doomed to repeat the lifestyle? Is alcoholism hereditary or environmentally influenced? Or…
