Symport is a form of active transport. It involves the movement of two or more substances across a cell membrane in the same direction, using energy typically derived from the electrochemical gradient of one of the substances. This process requires energy input because it often moves substances against their concentration gradients.
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.
The proteins may assist in the movement of substances by facilitated diffusion or active transport. These mechanisms of movement are known as carrier mediated transport.Each carrier protein is designed to recognize only one substance or one group of very similar substances. Research has correlated defects in specific carrier proteins with specific diseases.
Three physiological processes involved in absorption are diffusion, active transport, and facilitated diffusion. Diffusion is the movement of substances from an area of high concentration to an area of low concentration. Active transport requires energy to move substances against their concentration gradient. Facilitated diffusion involves the use of carrier proteins to help substances move across a cell membrane.

Active transport. It requires energy in the form of ATP to pump substances against their concentration gradient, from an area of low concentration to an area of high concentration. This process maintains the cell's internal environment and allows for the accumulation of certain substances within the cell.
Diffusion is the movement of substances from an area of high concentration to low concentration, while bulk flow is the movement of substances in a fluid due to pressure differences. Diffusion occurs passively, while bulk flow requires energy.
Electric energy requires the movement of electrons.
Yes, bulk flow requires energy as it involves the movement of substances in bulk, such as fluids or gases, from an area of higher pressure to an area of lower pressure. This movement is driven by the pressure difference, which requires energy to overcome resistance and move substances through a system or medium.
Active transport is a process that requires energy from ATP to move substances against their concentration gradient across membranes. This can occur through specific transport proteins known as ATPases or by coupling the movement of one substance with the energy generated from ATP hydrolysis.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
