Question 6 • Earth and Space Science

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

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

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.”
