Ion channels are a versatile group of membrane proteins that can be opened by various stimuli such as ligand binding. Once open,

ions move through these channels. The direction these ions move is determined by the concentration of the ions either side of the membrane, as well as by a second factor. What is this second factor?​

Ions are charged atoms or molecules. The plasma membrane is analogous to a capacitor, storing and separating charge. The voltage across the membrane varies from cell to cell, but a typical value is that the inside of the cell is -65 mV (millivolts) relative to the outside.

This may suggest that positive ions will flow into the cell when ion channels open, but, as mentioned in the question, the movement of ions is determined by both concentration and voltage.

This so called "electrochemical potential" can be calculated using the Nernst equation.

Dmitry_Shevchenko [17]

C

ATP is usually used in processes and biochemical reactions in the body that would not occur spontaneously hence require energy to proceed them forward.

Explanation:

One such process is the transport of molecules against the concentration gradient. This is akin to climbing a hill. The channels that carry the molecule against concentration gradient require energy in carrying the molecule from the low concentration outside the cell to high concentration inside the cell. This is called active transport. Facilitated diffusion use membrane channels too, but no ATP energy is consumed because the molecules are moving down concentration gradient.

Fire bricks absorb many btu’s, so once heated up only a small flame is required to maintain that heat/temperature.

The fire brick composition is mostly materials like alumina silica sand, clay, not very porous.

Based on the model explain whether the molecules shown crossing the membrane require energy to do so
Svetach [21]

Answer:

As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.

Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.

Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
