Much like cells are the fundamental unit of a living being‚ neurons are the fundamental unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the

These two pyruvates oxidize to release CO2 as waste‚ and turn into acetyl-CoA. Each acetyl-CoA then goes through the Kreb’s cycle‚ with multiple reactions producing a net total of six NADH‚ two FADH2 [another coenzyme]‚ two CO2‚ and two ATP. The NADH and FADH2 coenzymes then travel to the electron transport chain‚ where most of the ATP production begins. The NADH and FADH2 undergo redox reactions to send electrons through one member of the transport chain to another‚ which creates energy

everything from energy production in the body‚ to maintaining blood vessels to hormone metabolism. Most B vitamins work together and‚ in many cases‚ provide the greatest benefit when supplemented together in the correct ratios. The B vitamins act as coenzymes‚ compounds that unite with a protein component called an apoenzyme to form an active enzyme. The enzyme then acts as a catalyst in the chemical reactions that transfer energy from the energy drinks to the body. These vitamins are essential for the

use of a process known as oxidation to make fat acids and pyruvate acid into (indirectly) ATP and Pi (inorganic phosphate). The process goes as follows: 1) Oxidation of pyruvate acid into acetyl coenzyme A. 2) Oxidation of fat acids into acetyl coenzyme A. 3) Oxidation of acetyl coenzymes from step one and two into CO2 and NADH2. 4) Oxidation of NADH2 by oxygen forming water. 5) Synthesis of ATP coupled to NADH2 oxidation by process of oxidative phosphorylation. Most of this is

Today I will inform my audience of the history of Alzheimer’s ‚ what happens to the brain in alzheimers disease; the stages as well as treatment. Alzheimer’s disease is an irreversible‚ progressive brain disease that slowly destroys memory and thinking skills and‚ eventually even the ability to carry out the simplest tasks of daily living. In most people with Alzheimer’s‚ symptoms first appear after age 60 but it can precent itself sooner. Alzheimer’s disease is the most common cause of dementia
