Hodgkin and Huxley was significant in understanding how the neurons in our body work. They used a giant squid axon because it’s big and therefore makes it easier to measure voltages across the membrane of a cell. It help to understand how the action potential is reached by the cell by using an electrode measuring inside the cell and the ion flux content that’s outside the cell. Since nerve cells in humans are extremely small, they used giant squid axons to get a better understanding of how the…

speed, as electrical synapses allow action potentials to pass directly from neuron to neuron through the use of gap junctions. This direct passage and resulting speed of transmission isn’t present in chemical synapses. Chemical synapses rely on the transformation of the action potential into a chemical called the neurotransmitter, which is diffused across the synapse to bind to receptors in another neuron and then transformed into another action potential to continue the signal transmission…

Introduction: Temperature can affect the rate at which an action potential is generated to excite an action potential within a given skeletal muscle. Maximum contraction is the ability of the muscle to recruit and produce its greatest force during a contraction, and we can observe these effects by using a grip force transducer, which records the functional grip force of the hand. Therefore, the purpose of this lab was to discern how varying temperatures affect maximum contraction. I…

Genetic engineering is a very powerful and potentially dangerous scientific application used to modify/alter an organism 's DNA. This technique uses biotechnology, which is the use of genetic engineering for commercial purposes, to introduce a desirable trait into an organism by affecting it on a molecular level (UNL 's AgBiosafety for Educator). These kinds of methods involve the addition, replacement, or deletion of certain strands of DNA. Introductions of DNA can come from either the same or…

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…

Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…

This investigation focusses on an egg falling off a height of 4 metres in the fastest possible time without breaking the egg. In order to make this happen, an investigation must be conducted on the forces acting upon gravity, crumple zone theory, and energy transfer and absorption. The world is made up of matter and energy (Cool Cosmos, 2015). Matter is made up of atoms and molecules and these atoms and molecules are always in constant motion because of energy (Cool Cosmos, 2015). Gravity is…

Hydropower is power that is generated from a dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United…

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.…

###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,…
