How does the inside of the resting neuron compare to the outside in terms of electrical charge and Na plus concentration?
The concentration of negatively charged proteins and positively charged potassium ions, K+, is greater inside the cell than outside. In contrast, the concentration of sodium ions, Na+, is greater outside the cell than inside. The concentrations of Na+ and K+ ions are partly due to the action of the sodium-potassium pump, which actively moves Na+ out of cells while moving K+ in.
Is a carbon rod negatively charged?
A carbon rod itself is not inherently negatively charged; it is electrically neutral under normal conditions. However, if it gains excess electrons, it can become negatively charged. In certain applications, such as in electrochemical cells or batteries, carbon rods can serve as electrodes where charge can accumulate, leading to a negative charge.
What term is used to describe the process of creating charged particles that can damage living cells?
Ionization creates charged particles that can harm living tissues.
What substances are normally unable to pass through the glomerular walls?
Large molecules such as proteins, blood cells, and platelets are normally unable to pass through the glomerular walls due to their size. Additionally, negatively charged particles like albumin are also restricted from passing through as they are repelled by the negatively charged basement membrane of the glomerulus.
Acidic Congo red does not contain carbon particles like Nigrosin but can give the appearance of a negative stain What is the basis for this stain?
Acidic Congo red is a negatively charged dye that can stain the background of a specimen, giving the appearance of a negative stain. This effect is due to the electrostatic repulsion between the negative charge of the dye and the negatively charged cellular components, causing the dye to be excluded from the cells and stain the background instead.
When the cardiac cells are in resting and negatively charged state this is known as?
When cardiac cells are in a resting and negatively charged state, this is known as the resting membrane potential. This resting state allows the cells to be ready to receive and transmit electrical signals for proper heart function.
Why are basic dyes more successful on bacteria than acidic dyes?
Basic dyes are positively charged and can easily bind to the negatively charged components of bacterial cells, such as the cell wall. This makes them more effective at staining bacteria. Acidic dyes, on the other hand, are negatively charged and repelled by the negatively charged bacterial cells, making them less successful for staining bacteria.
How does the inside of the resting neuron compare to the outside in terms of electrical charge and Na plus concentration?
The concentration of negatively charged proteins and positively charged potassium ions, K+, is greater inside the cell than outside. In contrast, the concentration of sodium ions, Na+, is greater outside the cell than inside. The concentrations of Na+ and K+ ions are partly due to the action of the sodium-potassium pump, which actively moves Na+ out of cells while moving K+ in.
How osmosis works inside human body?
There are certain types of vitamins and minerals that exist inside cells and float around outside cells that are either positively and negatively charged. If the equilibrium of specific vitamins or a specific mineral is out and creates a deficit from its positive/negative charged counterpart vitamin or mineral; then water is the medium to increase or decrease the pressure of the cells absorption and nutrient uptake.
Why is the resting membrane potential negative in cells?
The resting membrane potential in cells is negative because of the unequal distribution of ions across the cell membrane, particularly the higher concentration of negatively charged ions inside the cell compared to outside. This creates an electrical gradient that results in a negative charge inside the cell at rest.
What causes the fall in membrane potential in cells?
The fall in membrane potential in cells is caused by the movement of ions across the cell membrane, specifically the exit of positively charged ions like potassium or the entry of negatively charged ions like chloride. This disrupts the balance of charges inside and outside the cell, leading to a decrease in membrane potential.
Are bones are living?
not really, bones are not living cells they are made of calcium mostly and are not living cells, although inside of the bones contain bone marrow, which are living cells
What term is used to describe the process of creating charged particles that can damage living cells?
Ionization creates charged particles that can harm living tissues.
Why is an egg a living cells?
because inside the egg is something living.
Why doesn't a negative stain colorize the cells in the smear?
A negative stain will stain the background with an acidic dye, such as Nigrosin. This procedure is used to demonstrate capsules. This technique brings the specimen off of the background for more adequate viewing purposes.
Why does nigrosin not stain bacterial cells?
Nigrosin is an acidic stain composed of large molecules that are repelled by the negatively charged bacterial cell surface. Bacterial cells typically have a negative charge due to components like lipopolysaccharides in their cell walls, which repel the negatively charged nigrosin dye, preventing it from staining the cells.
Viruses depend on living things for what?
Viruses depend on living cells because they reproduce inside of them.
