Cell Membrane Structure and Function

What is a cell membrane

• A cell membrane is a fluid-filled space that stores nutrients.
• A cell membrane is a type of organelle that produces proteins.
• A cell membrane is a rigid structure that provides energy to the cell.
• A cell membrane is a biological membrane that surrounds and protects a cell.

Whats the main fuctions of a cell membrane

• To store genetic information
• To produce energy for the cell
• To form a boundary between inside and outside of the cell controls passage of materials in and out

• To control the movement of substances in and out of the cell, provide protection, and enable cell communication.

What is Phospholipid

• Phospholipids are nucleic acids that carry genetic information.
• Phospholipids are carbohydrates that store energy in cells.
• Phospholipids are proteins that aid in cell division.
• Basic building block of the membrane

What is Hydrophilic head and Hydrophobic tails

• Hydrophilic head is water loving polar and hydrophobic tails is water fearing non polar fatty acids

• Hydrophilic head and hydrophobic tails are both parts of a molecule that repel water.
• Hydrophilic head refers to the oily part of a molecule, while hydrophobic tails refer to the water-loving parts.
• Hydrophilic head is the water-repelling part of a molecule, while hydrophobic tails are the water-attracting parts.

What is Phospholipid Bilayer

• A type of carbohydrate that stores energy in cells.
• The phospholipid bilayer is a double layer of phospholipids that forms the cell membrane, that also maintains homeostasis and fluid mosaic model.

• A single layer of proteins that surrounds the nucleus.
• A rigid structure that provides support to the cell.

What is cholesterol

• Cholesterol is a vitamin necessary for skin health.
• Cholesterol maintains membrane strength and integrity, while separating fatty acid tails

• Cholesterol is a carbohydrate that provides energy.
• Cholesterol is a type of protein found in muscles.

What is Glycolipids

• Glycolipids are nucleic acids involved in genetic coding.
• Glycolipids are lipids with carbohydrate (oligosaccharide) with cell stability and recognition

• Glycolipids are carbohydrates that store energy.
• Glycolipids are proteins that help in digestion.

What is Glycoproteins

• Glycoproteins are carbohydrates that have protein groups attached to them.
• Glycoproteins are lipids that contain sugar molecules.
• Glycoproteins are nucleic acids that are involved in protein synthesis.
• Glycoproteins are protein with carbohydrates with cell recognition and adhesion

What is transport (functions of membrane proteins)

• Transport functions of Channel and carrier proteins, act as gates for specific particles

• Membrane proteins are involved in energy production only.
• Transport functions are exclusive to carbohydrates in the membrane.
• Membrane proteins only serve as structural components.

Attachment & Recognition (Functions of Membrane proteins)

• Identification system attachment sites for various elements

• Energy production functions of membrane proteins.
• Signal transduction functions of membrane proteins.
• Transport and storage functions of membrane proteins.
