Question

1. describe diffusion. moves things into/out of the cell (circle one or both!) moves from high - to - low/low - to - high concentration (circle one) for large/small molecules (circle one or both!) uses/does not use protein doorway (circle one) moves things into/out of the cell (circle one or both!) moves from high - to - low/low - to - high concentration (circle one) for large/small molecules (circle one or both!) uses/does not use protein doorway (circle one) 29. describe facilitated diffusion: moves things into/out of the cell (circle one or both!) moves from high - to - low/low - to - high concentration (circle one) for large/small molecules (circle one or both!) uses/does not use protein doorway (circle one) 30. describe active transport: moves things into/out of the cell (circle one or both!) moves from high - to - low/low - to - high concentration (circle one) for large/small molecules (circle one or both!) uses/does not use protein doorway (circle one) 31. describe endocytosis: example of active/passive (circle one) moves things into/out of the cell (circle one or both!) for very large/small molecules (circle one or both!) 32. describe exocytosis: example of active/passive (circle one) moves things into/out of the cell (circle one or both!) for very large/small molecules (circle one or both!)

Explanation:

Diffusion is a passive - transport process. It moves substances into and out of the cell, from high - to - low concentration, mainly for small molecules and does not use a protein doorway. Facilitated diffusion also moves substances into and out of the cell, from high - to - low concentration, can be for large or small molecules and uses a protein doorway. Active transport moves substances into and out of the cell, from low - to - high concentration, can be for large or small molecules and uses a protein doorway. Endocytosis is an active process that moves substances into the cell, mainly for very large molecules. Exocytosis is an active process that moves substances out of the cell, mainly for very large molecules.

Answer:

1. Moves things into/out of the cell: both; Moves from high - to - low/low - to - high concentration: high - to - low; For large/small molecules: small; Uses/does not use protein doorway: does not use
2. Moves things into/out of the cell: both; Moves from high - to - low/low - to - high concentration: high - to - low; For large/small molecules: both; Uses/does not use protein doorway: uses
3. Moves things into/out of the cell: both; Moves from high - to - low/low - to - high concentration: low - to - high; For large/small molecules: both; Uses/does not use protein doorway: uses
4. Example of active/passive: active; Moves things into/out of the cell: into; For very large/small molecules: very large
5. Example of active/passive: active; Moves things into/out of the cell: out; For very large/small molecules: very large
