What is the source of the electrical energy in the brain?
The source of electrical energy in the brain is the movement of ions, such as sodium and potassium, across the cell membranes of neurons. This creates electrical impulses that allow for communication between brain cells.
When or where is ATP required in the process of water transport?
ATP is required during the active transport of ions across the cell membranes, particularly in the process of maintaining the concentration gradient of ions (like sodium and potassium) driving water movement in and out of cells. This energy is necessary for the functioning of specific ion pumps involved in water transport, such as the sodium-potassium pump.
When electric current is passed through a strong solution of brine then what will happen?
When electric current is passed through a strong solution of brine (sodium chloride in water), electrolysis occurs. Chlorine gas is produced at the anode, sodium metal at the cathode, and sodium hydroxide remains in solution. This process is known as the chlor-alkali process.
What transport mechanisms require energy?
Active transport mechanisms, such as the sodium-potassium pump in cell membranes, require energy in the form of ATP to move substances against their concentration gradient. Endocytosis and exocytosis, which involve the uptake and release of large molecules or particles by cells, also require energy.
Why do our sensory organs perceive light?
Rods and cones in the retina have photosensitive channels that open when a certain wavelength of light comes in contact. The open channels then either allow neurotransmitter or sodium to enter causing a chain reaction of the voltage gated Sodium Potassium pumps sending a signal down the bipolar neuron leading to the optic nerve.
What is the concentration of sodium chloride for haemolysis to occur in transport membranes?
ii dun knw
What is salt split technique?
It is a method used to split a salt ( for example sodium chloride ) in the corresponding ACID and BASE (i.e Hydrochloric acid and Sodium chloride in the example which has been taken ) . It is an eletrochemical process where we use ANION EXCHANGE MEMBRANES and CATION EXCHANGE MEMBRANES to serve our purpose of separating the Sodium and Chloride ions.
What would happen when sodium react with vinegar?
it produces sodium ethanoate
How did the discovery of sodium happen?
By bumping into it
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Yes, most animal cell membranes have protein pumps known as sodium-potassium pumps that actively transport sodium ions out of the cell and potassium ions into the cell. This helps maintain the cell's electrochemical gradient essential for various cellular functions.
What happen when Sodium chloride added with sodium rhodizonate?
Any reaction occur.
Which reaction will happen faster sodium with water or magnesuim with water?
Sodium wins!
Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?
The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.
Does sodium chloride effectively kill bacteria?
Yes, sodium chloride, also known as table salt, can effectively kill bacteria by disrupting their cell membranes and causing them to die.
What would happen if a chemically gated sodium channel in the postsynaptic membrane were completely blocked?
Blocking the chemically gated sodium channel in the postsynaptic membrane would prevent sodium ions from entering the neuron, hindering depolarization and transmission of the signal. This would effectively inhibit the neuron from responding to neurotransmitters released by the presynaptic neuron, leading to a disruption in neuronal communication and a potential loss of function in the neural circuit.
Which reaction will happen faster sodium with water or magnesium with water?
Sodium is MUCH faster.
What happens when sodium reacts wth sodium hydroxide?
nothing would happen. As there is sodium in both compounds nothing would react. At most depending on the levels and concentrations in this reaction you may get the sodium to disolve a little otherwise nothing will happen
