When no energy is present substances will naturally move from low to high concentration?
Actually, substances naturally move from areas of high concentration to low concentration, a process known as diffusion. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Energy is not required for this process; instead, it relies on the inherent kinetic energy of the molecules. In contrast, moving substances from low to high concentration requires energy input, typically through active transport mechanisms.

In order for substances to move through the cell membrane what must there be?
For substances to move through the cell membrane, there must be a concentration gradient, as substances will naturally move from an area of higher concentration to lower concentration through processes like diffusion or facilitated diffusion. Additionally, specific transport proteins or channels may be required depending on the size or charge of the substance being transported.
Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?
Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.
Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
Diffusion can occur with no?
Diffusion can occur with no membrane or barrier present. It is a passive process where molecules move from an area of high concentration to an area of low concentration. This is driven by the natural kinetic energy of molecules.
Is it true that active transport differs from passive transport in that it does not require an input of energy?
No, active transport requires an input of energy, usually in the form of adenosine triphosphate (ATP), to move substances against their concentration gradient. Passive transport, on the other hand, does not require energy and relies on the natural movement of substances down their concentration gradient.
Do Substances naturally diffuse up a concentration?
no down a concentration gradient high to low if its low to high it requires energy
Does passive transport move substances against the concentration gradient?
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
In order for substances to move through the cell membrane what must there be?
For substances to move through the cell membrane, there must be a concentration gradient, as substances will naturally move from an area of higher concentration to lower concentration through processes like diffusion or facilitated diffusion. Additionally, specific transport proteins or channels may be required depending on the size or charge of the substance being transported.
Moving substances from a lower concentration to a higher concentration requires . passive diffusion facilitated diffusion active transport pinocytosis?
Active transport. This process uses energy to pump substances against their concentration gradient, allowing them to move from areas of lower concentration to higher concentration.
Which membrane transport process will continue on even though the cell may be alive or dead?
Passive diffusion will continue even if the cell is dead, as it does not require energy input from the cell. Substances will naturally move down their concentration gradient from an area of higher concentration to an area of lower concentration through the cell membrane.
What are the two basic ways substances enter or exit a cell?
These are not necessarily the mechanisms, but I believe you are referring to active and passive transport. Active transport uses energy (from adenosine triphosphate, or ATP) to move solutes from an area of low concentration to an area of high concentration This movement is against the concentration gradient, so energy is required. Passive transport is when the solutes basically fall from an area of high concentration to an area of low concentration across a membrane. Since solutes naturally seek to equalize concentration across a membrane, no added energy is required for passive transport.
How does active transport enable the movement of substances from a low concentration to a high concentration within a cell?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration. This allows the cell to maintain specific concentrations of substances inside and outside the cell, which is important for various cellular functions.
Does some diffusion require energy?
No. Diffusion is a natural occurrence of the net movement of substances from a region of higher concentration to a region of lower concentration (down the concentration gradient).
How does active transport work against the concentration gradient to move substances across a cell membrane?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration, across the cell membrane. This is achieved by using specialized proteins called pumps that actively transport the substances across the membrane, requiring energy in the form of ATP.
Does oxygen and carbon dioxide moving from alveoli to capillaries requires energy?
It does not require energy. It move down the concentration gradient naturally.
What transport that requires no energy and moves substances from an area of high concentration to a lower concentration?
Your mom...........no I'm just kidding, but there are some cars that regire no energy, but just solar power.
When substances move through a cell membrane by diffusion the cell uses a lot of energy to move those substances. Is this true or false?
False. Diffusion is a passive process that does not require energy input from the cell. Substances move down their concentration gradient from an area of high concentration to an area of low concentration. The cell membrane facilitates this movement without the need for energy.
