Question

phospholipids are another type of lipid. they are the building blocks of cell membranes. the model shows the chemical structure of a phospholipid. select the true statements. carbon atoms are arranged in two long chains in phospholipids. phospholipids contain nitrogen and phosphorus atoms. phospholipids are energy - storage molecules.

Explanation:

• By observing the chemical - structure of phospholipid in the image, we can see two long chains of carbon atoms. Also, the structure contains nitrogen (in the nitrogen - containing group) and phosphorus (in the phosphate group). Phospholipids are mainly components of cell membranes and not energy - storage molecules. Energy - storage lipids are typically triglycerides.

Answer:

• Carbon atoms are arranged in two long chains in phospholipids.
• Phospholipids contain nitrogen and phosphorus atoms.
