Which process is responsible for moving cellular wastes across the cell membrane?
The process for moving cellular wastes across the cell membrane is known as active transport. Active transport is a source of energy that allows molecules to move from low concentrations to high concentrations, and provides the needed boost to move the molecules uphill.
What is the best definition of osomosis?
Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentrations on both sides of the membrane.
Does active transport move molecules against their concentration gradients?
Yes, active transport is a cellular process that moves molecules against their concentration gradients, requiring energy in the form of ATP to pump substances across the cell membrane. This process allows cells to accumulate molecules or ions at concentrations higher than their surroundings, enabling them to maintain internal balance and perform essential functions such as nutrient uptake and waste removal.
How does the process of active transport enable the movement of molecules against a concentration gradient?
Active transport is a process in which cells use energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This is achieved by using specialized proteins called transporters that pump the molecules across the cell membrane, requiring energy in the form of ATP. This allows the cell to maintain specific concentrations of molecules inside and outside the cell, which is important for various cellular functions.
Where does osmosis occur?
Osmosis occurs wherever there is a semi-permeable membrane that separates two solutions of different concentrations. This process allows water molecules to flow from the area of lower solute concentration to the area of higher solute concentration to balance out the concentrations on both sides of the membrane.
What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.
The energy-requiring process that moves molecules and ions across a cell membrane against a concentration difference is called?
Active transportation

Which process would be describe the movement of sugar molecules through membrane from a region of higher concentration to a region of lower concentration?
This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
Which process requires cellular energy to move molecules across the cell membrane from a region of lower concentrations to a region of higher concentration?
You are describing active diffusion.
Describe the process of osmosis?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. This process helps to balance the solute concentrations on either side of the membrane.
The process by which H2O diffuses across a membrane?
Water diffuses across a membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration, down its concentration gradient. This process helps to maintain the balance of water and solute concentrations on both sides of the membrane.
What is the best definition of osomosis?
Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentrations on both sides of the membrane.
What is the movement of which kind of molecules is controlled by osmosis?
The movement of water molecules is controlled by osmosis. Osmosis is the process by which water moves across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration in order to equalize the concentrations on both sides of the membrane.
