Question 10 • Earth and Space Science

What role do membrane proteins play in microbial degradation of hydrocarbons?

Answer
A
They convert hydrocarbons directly into CO sub 2 and cap h sub 2 cap o.
B
They release soap-like substances that break down oil droplets.
C
They cut hydrocarbon chains into smaller pieces.
D
They detect and attach hydrocarbons on oil droplets.

Explanation

Membrane proteins can recognize hydrocarbons and help microbial cells attach to them, bringing the cells into contact with the oil. This supports degradation, but the proteins do not directly convert hydrocarbons into carbon dioxide and water or cut the chains apart. The correct choice is D, “They detect and attach hydrocarbons on oil droplets.”
