Membrane proteins breakdown moklecules to move other molecules from low concentration to high concentration

Membrane proteins use the negative charge inside of the cell to increase the concentration of a chemical inside of the cell

|
Maintaining osmotic balance by taking in or releasing water to match the water concentration of the extracellular environment

|
Form the cell membrane around food to create a vacuole that is kept separate from the rest of the cytoplasm while enzymes break down the food.

Detailed explanation-1: -Membrane proteins allow chemicals to move from high concentrations to low concentration until equilibrium is reached. Maintaining osmotic balance by taking in water or releasing water to match the water concentration of the extracellular environment.
Detailed explanation-2: -Cells maintain homeostasis without using energy through passive transport. During passive transport, molecules move across the cell membrane from high to low concentration without using ATP. Passive transport helps get nutrients into the cell, such as glucose and oxygen.
Detailed explanation-3: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.
Detailed explanation-4: -Answer and Explanation: Osmosis helps maintain homeostasis by maintaining concentration of solvents and solutes constant inside cells. The cell membrane is selectively permeable. The cell membrane allows small uncharged molecules to passively pass through by simple diffusion.
Detailed explanation-5: -Some other examples of homeostasis are pH and nutrient levels. Diffusion is process by which particles move from an area where they are more concentrated to an area where they are less concentrated. When homeostasis is threatened in a cell, diffusion is used to keep the cell’s concentration balanced.
