Describe the role of carbon in biological systems. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
Understand the Problem
The question is asking to describe the role of carbon in biological systems and to explain how membrane fusion occurs between B cells and cancer cells, focusing on the interaction of phospholipids.
Answer
Carbon forms essential biomolecules. When cell membranes fuse, polar heads face outward and interact with the aqueous environment, while nonpolar tails face inward and interact with each other.
The final answer is: Carbon forms essential biomolecules such as DNA, RNA, and proteins through versatile bonding, supporting life functions, growth, replication, and energy storage. When the membranes are fused, the polar heads of phospholipids from both cells will interact with each other and the surrounding aqueous environment, while the nonpolar tails from both cells will interact with each other within the membrane's hydrophobic core.

The final answer is: Carbon forms essential biomolecules such as DNA, RNA, and proteins through versatile bonding, supporting life functions, growth, replication, and energy storage. When the membranes are fused, the polar heads of phospholipids from both cells will interact with each other and the surrounding aqueous environment, while the nonpolar tails from both cells will interact with each other within the membrane's hydrophobic core.
More Information
Carbon's versatility in forming four covalent bonds allows it to be the backbone of complex biomolecules. The amphipathic nature of phospholipids, with hydrophilic heads and hydrophobic tails, is crucial for forming functional cell membranes.
Tips
A common mistake is confusing the interaction of polar and nonpolar parts of phospholipids. Remember that polar heads face outward toward water, while nonpolar tails face inward, away from water.
