Diffusion refers to the movement of molecules from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion specifically for water molecules moving across a semi …

In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.

The steps of ion exchange carried out by the Na + / K + ATPase are depicted in the following diagram. Given the concentration gradient established by the Na + /K + ATPase, which of the following …

Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their …

Diffusion occurs when particles move from an area of high concentration to low concentration, creating a concentration gradient. This natural, energy-free process occurs due to the random movement of …

There are two main categories of passive transport: simple diffusion (sometimes called “diffusion”) and facilitated diffusion. Both types of passive transport involve substances moving across the cell …

To answer it, let’s take a step back and refresh our memory on why diffusion happens. In diffusion, molecules move from a region of higher concentration to one of lower concentration—not because …

Diffusion is the movement of particles down their gradient. A gradient is any imbalance in concentration, and moving down a gradient just means that the particle is trying to be evenly distributed …
