Question

passive transport
diffusion: movement of molecules from to concentration
is a type of diffusion that deals specifically with the movement of
an example in the human body
when a cell is in a solution it means there is a higher concentration of particles outside the cell than in
when a cell is in a solution it means there are equal concentrations of particles in and out of the cell
when a cell is in a solution it means there is a higher concentration of particles inside the cell than out
facilitated diffusion: passive transport through this happens when objects like are too big to pass through the membrane.
transport proteins change to allow certain particles in

active transport: requires in the form of movement of particles the concentration gradient (going from concentration to concentration)
protein pumps: particles are pumped across the membrane
example in the human body:

endocytosis:
example:

exocytosis:
example:

Explanation:

Diffusion is from high to low concentration. Osmosis is water - specific diffusion. In the human body, oxygen diffuses into cells. A hypertonic solution has more particles outside the cell, an isotonic has equal, and a hypotonic has more inside. Facilitated diffusion uses transport proteins for large molecules like glucose. Transport proteins change shape. Active transport needs energy (ATP) and moves against the gradient (low to high). In the human body, sodium - potassium pumps are an example. Endocytosis is the cell taking in substances (e.g., white blood cells engulfing bacteria). Exocytosis is the cell releasing substances (e.g., nerve cells releasing neurotransmitters).

Answer:

Diffusion: Movement of molecules from high to low concentration. Osmosis is a type of diffusion that deals specifically with the movement of water. An example in the human body is oxygen diffusing into cells. When a cell is in a hypertonic solution it means there is a higher concentration of particles outside the cell than in. When a cell is in an isotonic solution it means there are equal concentrations of particles in and out of the cell. When a cell is in a hypotonic solution it means there is a higher concentration of particles inside the cell than out. Facilitated Diffusion: Passive transport through transport proteins. This happens when objects like glucose are too big to pass through the membrane. Transport proteins change shape to allow certain particles in. Active Transport: Requires energy in the form of ATP. Movement of particles against the concentration gradient (going from low concentration to high concentration). Protein pumps: particles are pumped across the membrane. Example in the human body: sodium - potassium pump. Endocytosis: The cell takes in substances. Example: white blood cells engulfing bacteria. Exocytosis: The cell releases substances.
