Do cellular energy required for osmosis?
No, cellular energy is not directly required for osmosis. Osmosis is the movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, driven by the concentration gradient. However, cellular energy may be required for maintaining ion concentration imbalances that influence osmosis.
What is the natural tendency of molecules to spread from an area high concentration to an area of low concentration?
Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
Molecues of suger water oxygen and carbon dioxide do not require what to move from area of high to low concentration?
No energy is required to move molecules of oxygen, carbon dioxide, sugar, or water from areas of high to low concentration across a membrane. Instead, diffusion is used.
How does the process of active transport enable the movement of molecules against their 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 pumps that actively transport the molecules across the cell membrane. The energy required for this process is usually provided by ATP, the cell's energy currency.
Why is no energy required in passive transport processes?
In passive transport processes, no energy is required because molecules move across the cell membrane from an area of high concentration to an area of low concentration, following the natural flow of diffusion. This movement occurs spontaneously and does not require the cell to expend energy.
Is this correct no energy is required for the movement of water molecules across the cell membrane?
No, energy is required for the movement of water molecules across the cell membrane. This process is known as osmosis, where water moves from an area of low solute concentration to an area of high solute concentration, requiring energy to overcome the concentration gradient.

Osmosis is the movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, driven by the concentration gradient.

In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
Why is energy required in passive transport to occur?
Energy is not required for passive transport to occur. Passive transport processes such as diffusion and osmosis rely on the inherent kinetic energy of molecules to move from an area of high concentration to an area of low concentration without the need for external energy input.
Molecues of suger water oxygen and carbon dioxide do not require what to move from area of high to low concentration?
No energy is required to move molecules of oxygen, carbon dioxide, sugar, or water from areas of high to low concentration across a membrane. Instead, diffusion is used.
How might a cell overcome a concentration gradient?
A cell can overcome a concentration gradient by using active transport mechanisms such as pumping ions or molecules against their concentration gradient. This requires energy in the form of ATP to move molecules from an area of low concentration to an area of high concentration. Additionally, cells can also utilize facilitated diffusion where integral membrane proteins help transport molecules down their concentration gradient.
What is passive transportation of cells?
energy is not required for movement across membrane to occcur. molecules move from an area of high concentration to area of low conccentration

What is the mechanism by which molecules move from areas of low to high concentration, either actively or passively?
The mechanism by which molecules move from areas of low to high concentration is called active transport. This process requires energy to move molecules against their concentration gradient. Passive transport, on the other hand, allows molecules to move from areas of high to low concentration without the need for energy.
What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
Which method of material exchange uses up energy?
Active transport uses energy to move molecules against their concentration gradient across a cell membrane. Energy is required to pump molecules such as ions or nutrients from an area of low concentration to an area of high concentration. This process is driven by cellular energy sources such as ATP.
