The idea of concentrations and the gradients within them is important when understanding the movement of particles or molecules across cell membranes.

When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it ...

22 нояб. 2024 г. · Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.

The movement of a substance against its concentration gradient is called active transport. Active transport needs energy, which is generally supplied in the ...

In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient.

During primary active transport, ATP is required to move a substance across a membrane, with the help of membrane protein, and against its concentration ...

Active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration

19 сент. 2024 г. · Diffusion can be defined as: The movement of molecules from a region of higher concentration to a region of lower concentration.
