Question

have a (hydrophilic
head and a
hydrophobic tail
and make up the
plasma membrane
comprised of 2
fatty acid tails and a
glycerol phosphate
head
comprised of
glycerol and 3 fatty
acids
contain no fatty
acids
composed of a
carbon skeleton of
four fused rings
cholesterol,
testosterone, and
oestrogen are
examples
function as long-
term energy
storage
provide flexibility to
the plasma
membranes
fats and oils (1/3)
phospholipids (2/3)
steroids (3/3)

Explanation:

To solve this, we match the characteristics to each lipid type:

Fats and Oils (1/3)

• Look for "Comprised of glycerol and 3 fatty acids" (triglycerides have 1 glycerol + 3 fatty acids) and "Function as long - term energy storage" (fats/oils store energy long - term). Also, they "Contain no fatty acids"? No, wait—triglycerides have fatty acids. Wait, re - check: Fats/Oils (triglycerides) are glycerol + 3 fatty acids, and function in long - term energy storage. So the boxes for Fats and Oils:
• Comprised of glycerol and 3 fatty acids
• Function as long - term energy storage

Phospholipids (2/3)

• Phospholipids have "2 fatty acid tails and a glycerol phosphate head", are "hydrophobic tail and hydrophilic head", and "make up the plasma membrane". So the boxes:
• Comprised of 2 fatty acid tails and a glycerol phosphate head
• Have a hydrophilic head and a hydrophobic tail
• Make up the plasma membrane

Steroids (3/3)

• Steroids have a "carbon skeleton of four fused rings", examples like "Cholesterol, testosterone, and estrogen", and "Provide flexibility to the plasma membrane" (cholesterol in membranes). So the boxes:
• Composed of a carbon skeleton of four fused rings
• Cholesterol, testosterone, and estrogen are examples
• Provide flexibility to the plasma membrane
• Contain no fatty acids (steroids don’t have fatty acids)

Final Matching:

• Fats and Oils: Comprised of glycerol and 3 fatty acids; Function as long - term energy storage
• Phospholipids: Comprised of 2 fatty acid tails and a glycerol phosphate head; Have a hydrophilic head and a hydrophobic tail; Make up the plasma membrane
• Steroids: Composed of a carbon skeleton of four fused rings; Cholesterol, testosterone, and estrogen are examples; Provide flexibility to the plasma membrane; Contain no fatty acids

(If the task was to fill the boxes, this is how each lipid type aligns with the characteristics.)
