Question

One of the grand challenges in biology is understanding how the first cells formed on Earth. Since all cells are bound by a cell membrane, origin of life researchers are interested in modeling what the first membranes may have been like. What types of molecules might these researchers consider to be the original building blocks of cell membranes?Choose one:A. amphipathic moleculesB. hydrophobic moleculesC. carbohydrate moleculesD. hydrophilic molecules

Answer 1

Answer:

Option A. amphipathic molecules

Explanation:

Amphipathic molecules have both polar and non-polar parts which means they contain hydrophilic and hydrophobic regions in their structure.

These molecules are found in lipids. More specifically, phospholipids are considered as the fundamental building block of the cell membrane. They are arranged in a bi-layer having a hydrophilic head and hydrophobic tails to maintain the fluidity of the membrane.
