• hydrophilic heads
• hydrophobic tails
• water loving
• water fearing
• solvent loving
• lipid tails
• polar heads
• sugar tails
• protein heads
• oil loving

The phospholipid ​head (a)   while the tails ​ (b)   .

• interacts with water
• do not interact with water
• attract bacteria

Parts of the cell membrane?

• DNA, RNA, nucleotides, and amino acids
• Starch, cellulose, glycogen, and chitin
• Iron, zinc, copper, and magnesium
• Phospholipids, cholesterol, proteins, and carbohydrates
• Water, salt, oxygen, and carbon dioxide

Which proteins are in the cell membrane?

• Integral proteins, peripheral proteins, and glycoproteins.

• Mitochondria and ribosomes
• Lipids and carbohydrates
• Nucleic acids and enzymes
• Cholesterol and water

Glycoproteins are found in the cell membrane. What is their function?

• Glycoproteins in the cell membrane function as energy storage units
• The function of glycoproteins in the cell membrane is to produce ATP
• The function of glycoproteins in the cell membrane is to serve as recognition sites for other cells and molecules.
• The function of glycoproteins in the cell membrane is to regulate cell division
• Glycoproteins in the cell membrane serve as receptors for light waves

Peripheral proteins are found in the cell membrane. What is their function?

• Peripheral proteins help facilitate cell communication

• Peripheral proteins help transport molecules in and out of the cell

• Peripheral proteins help maintain the cell's shape

• The function of peripheral proteins is to store energy in the cell membrane
• Peripheral proteins are responsible for producing hormones in the cell membrane

What is the the function of a integral protein in the cell membrane?

• The function of an integral protein in the cell membrane is to provide structural support to the membrane
• The function of an integral protein in the cell membrane is to store energy for the cell
• The function of an integral protein in the cell membrane is to act as receptors for signaling molecules

• The function of an integral protein in the cell membrane is to transport molecules across the membrane

• The function of an integral protein in the cell membrane is to regulate the temperature of the cell

What is the difference between glycoproteins and peripheral proteins?

• Glycoproteins are only found in the nucleus, while peripheral proteins are only found in the cytoplasm.
• Glycoproteins are proteins found only in animal cells, while peripheral proteins are found only in plant cells.
• Glycoproteins are involved in cell signaling, while peripheral proteins are involved in DNA replication.
• Glycoproteins are larger in size compared to peripheral proteins.
• Glycoproteins are proteins with attached carbohydrates, while peripheral proteins are proteins that are not embedded in the lipid bilayer of the cell membrane.
