What else can I help you with?
Is passive transport able to occur against the concentration gradient?
No, passive transport cannot occur against the concentration gradient. It only moves substances from an area of high concentration to an area of low concentration.
What makes passive transport passive?
Passive transport is called passive because it doesn't require chemical energy intervention to occur. The four main types of passive transport are diffusion, facilitated diffusion, osmosis, and filtration.
The type of transport that requires no cellular energy?
Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
How is active transport different from passive transport, and what are two ways in which they contrast in terms of their mechanisms?
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy input from the cell, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, passive transport does not require energy and relies on the natural movement of molecules from areas of high concentration to low concentration. One way in which active and passive transport contrast in terms of their mechanisms is that active transport uses specific carrier proteins to transport molecules, while passive transport can occur through simple diffusion or facilitated diffusion. Another difference is that active transport can move molecules in both directions across the membrane, while passive transport typically only moves molecules in one direction.
How do molecules move by passive transport?
Molecules move by passive transport down their concentration gradient, from an area of higher concentration to an area of lower concentration, without the input of energy. This can occur through simple diffusion, facilitated diffusion, or osmosis, depending on the properties of the molecules and the cellular environment.
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.
Passive transport occur when small particles move from?
outside a cell
Is passive transport able to occur against the concentration gradient?
No, passive transport cannot occur against the concentration gradient. It only moves substances from an area of high concentration to an area of low concentration.
What is the defference between active transpors and passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
Is there Concentration in Passive Transport?
Absolutely, in order for passive transport to occur, the concentration on one side of the membrane must be larger than the concentration on the other side of the membrane. The molecules move from higher to lower concentration.
Diffusion across a membrane that requires no energy to occur is a process known as?
this is known as "passive transport"

Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
Is a cell required for passive transport?
No. Diffusion (passive transport) can take place without a cell. For example, if you were to put some coloured food dye into a cup of water, the food dye would spread until it eventually was a uniform colour. This is the process of diffusion, which is the movement of a substance down a concentration gradient. Passive Transport means no energy is required.
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
Does diffusion require the cell to respire?
Diffusion is a form of passive transport, so nothing is required for it to occur.
Is sugar osmosis or passive transport or active transport?
Sugar transport can occur through both passive transport, such as facilitated diffusion or simple diffusion, and active transport, such as primary or secondary active transport processes. Osmosis specifically refers to the movement of water across a semi-permeable membrane, so sugar transport itself is not osmosis.
