Because some cellular processes depend on a concentration difference across membranes.
Yes, active transport moves substances against the concentration gradient.
Yes, active transport moves substances against their concentration gradient.
The movement of substances against their concentration gradient is an active process.
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 biological systems, active transport moves substances 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.
Active transport
Active transport is the process that most likely takes place to remove substances from a cell against the concentration gradient. This process requires energy (usually from ATP) to move molecules or ions across the cell membrane, against their concentration gradient.
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
Active transport expends energy to move substances against a concentration gradient.
Bulk transport, also known as bulk flow or vesicular transport, can occur in both directions relative to the concentration gradient. When substances are moved against their concentration gradient, this process is typically active transport, requiring energy (usually in the form of ATP). Conversely, when substances are moved along their concentration gradient, it is considered passive transport. Overall, bulk transport encompasses mechanisms that can handle both scenarios.
Active transport moves substances against the concentration gradient by using energy from ATP to pump molecules or ions across the cell membrane, creating a higher concentration on one side than the other. This process allows the cell to maintain internal balance and control the movement of specific substances.
