What are some examples of action potentials? + Example - Socratic
2014年9月28日 · The most famous example of action potentials are found as nerve impulses in nerve fibers to muscles. Neurons, or nerve cells, are stimulated when the polarity across their plasma membrane changes. The polarity change, called an action potential, travels along the neuron until it reaches the end of the neuron. If a depolarizing graded potential is sufficiently large, Na+ channels in the trigger ...
What is solute potential? - Socratic
2014年11月14日 · Solute potential (also known as Osmotic potential) is shown with this symbol: Ψ But getting to your question, solute potential is a component of water potential. It happens because solute molecules are present. It is always negative since solutes lower the water potential of the system. So if you fully want to understand solute potential, here is a quick explanation of water potential ...
Explain how force, energy and work are related? | Socratic
2015年9月30日 · Force is a push or a pull, and the displacement of an object due to the application of a force on it is work. The ability to do work is called energy. Force is a push or a pull. If an object of mass m kg at rest is pushed, or pulled, such that it has an acceleration of a m/s^2, the force is equal to m*a. The displacement of the mass due to the force, F, being applied is s meters, so the work ...
What is the Nernst potential? + Example - Socratic
2015年10月25日 · E=E^@-(RT)/(nF)logQ Nernst equation is derived from the thermodynamic expression of free energy: DeltaG=DeltaG^@+RTlnQ and we know that G=-nFE, therefore, Nernst equation will be: E=E^@-(RT)/(nF)logQ where Q is the reaction quotient, R is the universal gas constant R=8.3145 J/(mol.K), F is Faraday's constant F=96485 C/(mol e^-) and T is the temperature in Kelvin.
What is the ionization potential? + Example - Socratic
2017年10月21日 · Ionization potential is the energy associated with the formation..... Ionization potential is the energy associated with the formation of ONE MOLE of gaseous cations PLUS one mole of gaseous electrons FROM one mole of gaseous atoms..... And thus it is the enthalpy change of the reaction.....
What are the ways that drugs can affect synaptic transmission?
2016年4月3日 · Example: Hydrazinopropionic acid inhibits biosynthesis of GAD enzyme required for GABA biosynthesis. Rate of release of neurotransmitters Neurotransmitters are released into the synapse via exocytosis. Exocytosis is a complicated process requiring many structural proteins such as SNARE proteins. Selectiveness of exocytosis is also a ...
What are some examples of the principle of conservation of …
2015年10月5日 · Examples include a pendulum, a ball tossed up in the air, a skier sliding down a hill and the generation of electricity inside a nuclear power plant. The principle of the conservation of energy says that energy within an isolated system is neither created nor destroyed, it simply changes from one type of energy to another. The most difficult part …
When wood is burned, new substances are produced. What kind
2018年4月16日 · See below: Wood is mostly made up of Cellulose, which is a polymer made up of many beta-glucose molecules.- The breakdown of cellulose by burning it is a combustion reaction as we burn something in oxygen. So technically, burning wood is chemically similar to the metabolic breakdown of carbohydrates in your body to produce energy. So the reaction of burning wood would more or less be ...
Physical and Chemical Changes - Chemistry - Socratic
Acting upon matter can cause it to change, but it is useful to separate these changes into two different categories: physical and chemical. A chemical change describes a process that changes one material into another. Burning wood causes it to turn into ash, a different material. A physical change is simply changing the shape or state, such as cutting a piece of wood into two pieces.
What is the equation that connects pH and its effect on electric ...
2017年8月7日 · Well, first off, you'll need to begin with the Nernst equation: E_(cell) = E_(cell)^@ - (RT)/(nF) lnQ where: E_(cell) is the overall cell potential. ""^@ indicates "1 atm" and 25^@ "C". R and T are known from the ideal gas law. n is the mols of electrons reportedly transferred in the redox reaction. F = "96485 C/mol e"^(-) is Faraday's constant. Note that "pH" only affects reactions that are ...
