Based on the requirements for channel and carrier proteins to move the molecules (shown in green) across the membrane, what can be concluded about the molecules?A) They are hydrophobic molecules. B) They require energy to move through the membrane. C) They are too large to move through the phospholipids directly. D) They are too charged or polar to move through the phospholipids directly?

Explanation:
Polar molecules are hydrophilic but lipophobic

Answer:
They are too charged or polar to move through the phospholipids directly.
Option D
Explanation:
The carrier proteins are the transporter proteins that help the molecules to pass through the Phospholipids bi-layer membrane directly. These molecules are generally highly polar or charged.
These molecules like water, metal ions, etc. cannot pass the Phospholipids bi-layer directly. So, they need the help of carrier proteins that help in bypassing the hydrophobic lipid layer and help the molecules to pass without spending any energy.
