Question

go online to bozemanscience.com → biology → cells → transport across the cell membrane. watch the video and answer the questions below. pause as needed. transport passive uses no ____ active uses __ diffusion facilitated diffusion proteins endo/exocytosis osmosis diffusion of __ uses:__ ex:____ phospholipid bilayer: draw/label a phospholipid. draw and explain how phospholipids arrange themselves to form the membrane

Explanation:

Passive transport does not use energy. Active transport uses energy. Facilitated diffusion uses transport proteins. Osmosis is the diffusion of water. An example of a protein - mediated active - transport is the sodium - potassium pump. Phospholipids have a hydrophilic head and hydrophobic tails. They arrange themselves in a bilayer with heads facing outward (towards water) and tails inward to form the cell membrane.

Answer:

Passive: Uses no energy
Active: Uses energy
Facilitated Diffusion: Uses transport proteins
Osmosis: Diffusion of water
Proteins (Active Transport example): Sodium - potassium pump
Phospholipid: Has a hydrophilic head and hydrophobic tails. Arrangement: In a bilayer with heads facing water (outward) and tails inward to form the cell membrane.
