  • Simple diffusion and passive transport (article) | Khan Academy
    Covers selective permeability of membranes, diffusion, and facilitated diffusion (including channels and carrier proteins)
  • Facilitated diffusion (video) | Khan Academy
    Facilitated diffusion is a type of passive transport that uses specialized proteins, such as channel proteins and carrier proteins, to help molecules move across a cell membrane In this process, molecules can move down their concentration gradient without requiring any energy input from the cell
  • Passive transport review (article) | Khan Academy
    TLDR: Facilitated diffusion happens with large or polar molecules and requires transport proteins Diffusion happens with small or nonpolar molecules and does not require any type of protein because the substance can diffuse directly across the lipid bilayer
  • Passive transport and active transport across a cell membrane article
    Simple diffusion can be disrupted if the diffusion distance is increased If the alveoli in our lungs fill with fluid (pulmonary edema), the distance the gases must travel increases, and their transport decreases Facilitated diffusion is diffusion that is helped along (facilitated by) a membrane transport channel
  • Khan Academy
    Learn about diffusion and passive transport, including how molecules move across cell membranes without energy input, on Khan Academy's biology resource
  • Passive transport and selective permeability - Khan Academy
    Passive transport describes the movement of substances across a cell membrane down their concentration gradients, which does not require energy Cell membranes are selectively permeable, so only certain substances can passively diffuse directly across the membrane These substances include small, nonpolar molecules such as carbon dioxide and molecular oxygen
  • Active transport review (article) | Khan Academy
    Facilitated diffusion is a type of passive transport and along the gradient Think of a pipe connecting a full tank of water to an empty one Active transport is against the gradient Think of a pump moving water from a nearly empty tank to an almost full one
  • Active transport: primary secondary overview (article) - Khan Academy
    Here, the cell can't import glucose for free using diffusion, because the natural tendency of the glucose will be to diffuse out rather than flowing in Instead, the cell must bring in more glucose molecules via active transport 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
  • Homeostasis and cellular transport (article) | Khan Academy
    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 membrane down a concentration gradient So, simple diffusion and facilitated diffusion do not require an input of energy
