Fosfolípido

The transcript explains the dual nature of phospholipids, which have both hydrophobic and hydrophilic properties. This unique characteristic is crucial for their role in biological systems, particularly in forming cell membranes.

What characteristic of phospholipids allows them to repel water?

• Their hydrophilic nature

• Their hydrophobic nature

• Their ionic bonds

• Their polar structure

What makes one end of a phospholipid molecule hydrophilic?

• The lipid tail

• The hydrogen bonds

• The carbon chain

• The phosphate group

Why is the dual property of phospholipids important in biological systems?

• It makes them resistant to temperature changes

• It allows them to dissolve in water

• It enables them to form cell membranes

• It helps them store energy

What is the primary component of cell membranes?

• Nucleic acids

• Carbohydrates

• Proteins

• Phospholipids

Which of the following best describes the structure of cell membranes?

• They are formed by proteins

• They consist of nucleic acids

• They are composed mainly of phospholipids

• They are made up of carbohydrates
