Question

2. Describe the permeability of cell membranes. How to substances cross cellmembranes? Utilize the terms bi-polar, semi-permeable, diffusion, active transport, membrane
proteins, endocytosis, exocytosis, vesicles, phagocytosis, pinocytosis, etc. (This should be 3-4paragraphs long)

Answer 1

The permeability of a cell membrane simply means the ability of the cell membrane to allow solutes and solvents diffuse or pass through it

In biology, substances moves in and out of cells through semi-permeable membranes of the cell in a function of different metabolic processes such as:

• Osmosis: This is the movement of substances from a region of low concentration to a region of high concentration
• Diffusion: This is the movement of substances from a region of high concentration to a region of low concentration
• Phagocytosis: This involves the movement of substances through phagocytic bacteria
• Endocytosis: This involves the movement of substances into the cell
• Exocytosis: This involves the movement of substances outside the cell environment
• Pinocytosis and others

So therefore, thee permeability of a cell membrane simply means the ability of the cell membrane to allow solutes and solvents diffuse or pass through it
