Daily Review Flashcard - Cell Membrane Structure (Task 11)

Front

What is the primary component that makes up the cell membrane?

Back

Phospholipids

Front

What type of macromolecule makes up the tail of the phospholipid?

Back

Lipid (fatty acid)

Front

What does the suffix -philic mean?

Back

Loving

Front

How does a cell maintain homeostasis?

Back

By regulating what enters and leaves the cell.

Front

What molecule makes up the polar, 'water-loving' head of the phospholipid?

Back

Phosphate

Front

What is the function of the cell membrane?

Back

To act as a protective barrier and regulate the movement of substances in and out of the cell.

Front

What are the two main parts of a phospholipid?

Back

A hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails.

Front

What role do proteins play in the cell membrane?

Back

They assist in transport, act as receptors, and provide structural support.

Front

What is the significance of the fluid mosaic model?

Back

It describes the cell membrane as a flexible structure with various proteins embedded in or attached to a double layer of phospholipids.

Front

What is the difference between hydrophilic and hydrophobic molecules?

Back

Hydrophilic molecules are attracted to water, while hydrophobic molecules repel water.
