Chapter 2.5, Problem 2MQ
Summary Introduction
The presence of outer membrane in a gram-negative bacteria provides only a modest strength to the cell. However, it plays a potential role in protecting the cytoplasmic membrane from several agents like lipophilic antibiotics and various substances harmful to the membrane. In addition to protein and phospholipid, it also comprises of polysaccharide. The polysaccharide and lipid molecules connect with each other to form a complex. Thus, the outer membrane is also referred to as the lipopolysaccharide layer (LPS).

Q1. You are required to design a carbon-based, eukaryotic, unicellular organism that contains membrane-bound organelles that match those on Earth. Describe specific structures and components that you would include in the cell wall, plasma membrane and internal cell membranes of your cell that would assist the cell's survival in the low temperatures and high pressure experienced on Kepler-28d. Specfically, mention what can be added to internal cell membranes, structure wise and components (200 words maximum)
