Answer:

Control of Cell Volume and Membrane Potential Basic

Basic problem

• The cell is full of components like Proteins, ions, fats, etc.

• Ordinarily, these would cause huge osmotic pressures, sucking water into the cell.

• The cell membrane has no structural strength, and the cell would burst.

Basic solution to the problem above

• Cells carefully regulate their intracellular ionic concentrations in order, to ensure that no osmotic pressures arise

• Consequently, the major ions Na+, K+, Cl- and Ca2+ in the cell have different concentrations in the extracellular and intracellular environments.

• And thus a voltage difference arises across the cell membrane.

Essentially two different kinds of cells: excitable and nonexcitable.

• All cells have a resting membrane potential, but only excitable cells modulate it actively.

Explanation:

In the case where there is a poisoning of the Na-K exchange pump.

Inhibition kicks off.

The pump requires binding by Na+ , K+ and ATP for its operation. Therefore , if the concentration of any of these substances is too low, the pump does not function.

When the temperature is reduced. During oxygen lack. Metabolic poisoning thus prevents the formation of ATP.

Potential buildup in the Na+ ion will be used by many different processes e.g cotransporter, neuron signalling etc.

Three substances A, B, and C melt at 00C,500C and -1500C
Drupady [299]
Answer:

That information is better presented and analyzed in a table.

This table shows you all the information and the answers:


Substance         melting point   boiling point    room temperature    conclusion
                                    °C                  °C                      °C                    (state)


A                                  0                    100                    25                    liquid

B                                  50                  200                    25                    solid
C                               -150                   10                     25                    gas

Explanation:

1) Substance A at 25° is above the melting point and below the boiling point, then it is liquid (just like water)


2) Substance B at 25°C is below the melting point, so it is solid.

3) Substance C at 25°C is above the boiling point, so it is gas.

the average kinetic energy of the particles in a gas increases as the temperature of the gas increases. explain​
sveticcg [70]

Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.
