How many moles of solute particles are in a solution with 0.50 moles of glucose and 2.0 kg water?
The solution is 0,25 M.
What functions to membrane proteins have?
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
How can methylene blue change the solute potential of the cell?
Methylene blue is a membrane-permeable dye that can enter the cell and bind to cellular components, such as proteins and nucleic acids. This binding can alter the osmotic properties of the cell and affect its solute potential. Methylene blue can also disrupt the electron transport chain in mitochondria, leading to changes in cellular metabolism and solute potential.
What does cell membrane in an animal cell?
plasma membrane in animal cell have many functions which r under: 1-it protects the cell from outside any activity. 2-it give shape to the cell. 3-its main function is to transport food particles nd water nd fluid to inside nd outside the cell. 4-it give support nd frame work to the cell. 5-many orgenells r bounded with cell membrane or plasma membrane during invagination process. 6-it maintains osmotic pressure,turgor pressure,water potential nd maintain the environment of the cell . 7-it works during exocytosis nd endocytosis. 8-it works during hypotonic nd hypertonic environment.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
How many moles of solute particles are produced by adding one mole of sodium nitrate to water?
two moles
What would happen if a cell containing many dissolve solutes was placed in pure waters?
Water would enter the cell via osmosis and it would finally burst.
How many moles of solute particles are in a solution with 0.50 moles of glucose and 2.0 kg water?
The solution is 0,25 M.
How many moles of solute particles are present in 1mL exact of aqueous 0.990 M CuSO4?
M = moles solute/ Liters solution 1 mL= 0.001 L 0.990M x 0.001 L =9.9 x 10^-4 moles CuSO4 9.9 x 10^-4 *2 = 0.00198 solute particles *When you dissolve 1 mole CuSO4 in water, it dissolves into 1 mol of Cu+ ions and 1mol of SO4- ions, which gives you twice as many moles of solute particles- which is why you multiply 9.9 x 10^-4 by 2. Hope this helps
What subatomic particles are found outside the atomic nucleus?
The particles outside of an atom are called electrons :D
What energy from outside the cell is responsible for many mutations?
radiation
How does a particle theory explain how a solute dissolves into a solvent?
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
What functions to membrane proteins have?
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
What is your conclusion to osmosis?
Osmosis can be defined by many example one is when slices of the potato are mixed with a high concentration of salt solution we can see the potatoes are shrink because the water from potato moves to the salt solution. Osmosis may occur when there is a partially-permeable membrane, such as a cell membrane. When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration (outside the cell) to one of high solute concentration (inside the cell), this is called osmosis. The cell membrane is selectively permeable, so only necessary materials are let into the cell and waste left out. Plant cell under different environments Osmotic pressure is the main cause of support in many plants. The osmotic entry of water raises the turgor pressure exerted against the cell wall, until it equals the osmotic pressure, creating a steady state.
Why do cells shrink and swell?
Cells burst due to the osmotic effect. This is where the concentration of water outside the cell is greater relative to the concentration of water inside the cell. The water will flow through the cell wall and into the cytoplasm. This makes the cell turgid. If the concentration gradient is very steep, enough water will enter the cell so as to make it burst. The opposite happens if there is a greater concentration of water inside the cell - water will exit the cell and cause it to shrivel.
What is van't hoff's factor?
Van't Hoff factor expresses how many ions and particles are formed, on average, in a solution from one formula unit of solute. It is the ratio between the actual concentration of particles produced when a substance is dissolved, and the concentration of a substance as is calculated from its mass.
How can methylene blue change the solute potential of the cell?
Methylene blue is a membrane-permeable dye that can enter the cell and bind to cellular components, such as proteins and nucleic acids. This binding can alter the osmotic properties of the cell and affect its solute potential. Methylene blue can also disrupt the electron transport chain in mitochondria, leading to changes in cellular metabolism and solute potential.
