Chemical potential

you get on the coaster. When our marble is released at the top of the initial hill, energy is transferred from potential energy to kinetic energy. Potential energy is higher than kinetic energy at the top of the hill, because the ride is barely, or not moving at all, and all of the energy is yet to be released. As the marble starts to go down the hill, energy is changed from potential to kinetic.…

Ava Lilienthal Science Barcus 7-4 The Physics Behind Soccer Soccer really has a lot to do with science. From Newton’s laws of motion to the momentum of the person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest…

allows calcium ions to enter the cell membrane, the synaptic vesicles move forward and release acetylcholine (ACH). ACH combined with membrane receptors on the endplate cause electronic potentials, potassium and sodium ions exchanging start to spread both sides of muscle cell membrane to form the action potentials, and long with the cell membrane so that both sides of the terminal cistern will release Ca2+, Ca2+ and troponin binding to change tropomyosin, let actin exposed binding site to the…

healthy tissue in the nervous system. Multiple sclerosis happen when T cell become activated. They enter CNS through blood vessels. T cells attacks myelin and produce damaging inflammation. Once in CNS, these T cell injured myelin and secrete chemicals which is cytokines to form scar tissues (sclerosis) that damage nerve fibers (axon) and recruit more damaging immune cells to the site of inflammation.When a part of myelin sheath is damaged, myelin sheath cannot act as insulator properly, so…

PKMz putatively facilitates LTP by maintaining trafficking of the Glu2R subunit of the AMPA receptor to the post-synaptic density, increasing the local synaptic potential and lowering threshold to depolarization at the membrane [28]. PKMz inhibitors can erase memories up to 3 months old, and GluA2 endocytosis inhibitors can block the loss of memory associated with ZIP [3]. Based on these observations, it has been…

COASTER LOOPS WORK When a roller coaster starts, there is most likely the first hill that is the biggest out of all the others. The reason for this is because at the top of the first hill, there is the maximum potential energy. As soon as the car starts moving down the hill, that potential energy turns into kinetic energy…

How one acts, thinks, or feels all come from the body’s nervous system. The nervous system is the body’s communication center that transmits thoughts and actions from the brain and spinal cord to a body part(s).The nervous system is made up of two parts- the peripheral nervous system and the central nervous system. The peripheral nervous system is a system outside the brain and spinal cord and it connects the central nervous system to the rest of the body. The central nervous system controls…

relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where the V_m moved away from 0 mV and became negative (Figure 1).…

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

###image messes with formatting). Some channels have evolved to also sense changes in the electrical potential across a membrane. A potential above a certain voltage will trigger the opening of these ion-conducting pores, releasing large stores of ions across the membrane. These voltage-gated ion channels allow for the generation of electrical stimuli (the firing of neurons via the action potential; Fig.1b###) that can travel long distances in the body, enabling functions such as heartbeat,…
