The host says that the polar compounds get "stuck" at the hydrophobic core as the reason why polar compounds cannot cross the membrane. sometimes people even describe this as the hydrophobic core "repels" polar compounds. this reasoning is wrong! 1. polar compounds are forming bonds with the water on the outside of the membrane. these bonds are called hydrogen 2. can polar compounds interact in this same way with the hydrophobic tails of the phospholipids? (yes or no) no 3. do interactions form between polar compounds and the hydrophobic tails? (yes or no) no 4. in order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many bonds it has formed with the water and enter into a space where these bonds cannot form. therefore, it is not a repelling action but a "lack of attraction."

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
