The fluid mosaic model explains:
Select one:
A. why active transport occurs across a cell membrane.
B. the arrangement of cell membrane components.
C. the movement of sodium ions across the cell membrane.
D. why fluids collect in a cell under hypotonic conditions.
Answer (2)
The fluid mosaic model explains the arrangement of cell membrane components. It states that the membrane components are constantly moving. The phospholipid bilayer compromises hydrophobic fatty acid tails and hydrophilic phosphate heads, this hydrophilic/phobic nature determines the unique structure of membranes.
The fluid mosaic model explains the structure and arrangement of components within the cell membrane, characterized by a flexible phospholipid bilayer with embedded proteins. This model provides insight into how these various elements work together to maintain cellular functions. Therefore, the correct answer is B. the arrangement of cell membrane components.
