What Is Neurotransmitter? Neurotransmitter is a chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve‚ muscle‚ organ or other tissue. (Webster new world medicine dictionary. http://www.medterms.com/script/main/art.asp?articlekey=9973) What are Hormones? Hormones are chemicals that carry messages from organs of your body to your cells. The glands that secrete hormones are part of the endocrine system (pituitary‚ thyroid‚ adrenals

Acute data analysis Due to the insignificant difference in the buffered and unbuffered D. magna acute studies‚ my hypothesis of the unbuffered concentration having a lower LC50 concentration was not supported. However‚ the indifference might suggest that the toxicity comes from the structure of the compound and not the fact that it is acidic. The pH in the buffered 625 mg/L was essentially neutral and yet it had caused the same mortality of its unbuffered counterpart. This information rejects the

Daphnia are cold-blooded poikilotherms that rely on heat from the surrounding water to maintain their body temperature. An increase in the water temperature should equate to an increase in metabolic activity due to enzymes working at a temperature closer to their optimum level. However‚ once the optimum temperature has been exceeded‚ the enzymes will begin to denature. Hydrogen bonds‚ which keep the protein conformation‚ begin to break‚ causing a change in shape of the active site; substrates

stimulatory signal produced when excitatory neurotransmitters activate different neurons in the central nervous system (CNS). Thus‚ when they are inhibited by caffeine‚ the stimulatory signal remains active for a longer period of time resulting in a greater sense of alertness (a CNS effect) but also a higher heart rate‚ blood pressure and respiratory rate. Caffeine also acts as a stimulant drug‚ causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption

that if Daphnia are placed in differently concentrated solutions of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of calcium chloride‚ one or more of the Daphnia died

Our environment is affected by many pollutants on a daily bases forming a threat to natural stability. For example some of the most polluted parts of the environment are bodies of water like that explained in our lab. Once pollution occurs

Neurotransmitter Switching in Adult Brain According to one dogma of neuroscience‚ neurotransmitter population was thought to be fixed and immutable throughout life once developmental stages have passed. For over 100 years‚ a central assumption in the field of neuroscience has been that the brain of the adult mammals should remain structurally constant. New neurons‚ as well as new neurotransmitters were thought not to be added to the adult mammalian brain and that the production of new neurons would
