22. Describe the structure and model of the cytoplasmic membrane in both gram positive and gram negative Bacterial cells.
Homework Answers
Both gram positive and negative bacteria contains cell wall made up of peptidoglycan. An additional layer of glycocalyx called capsule ( also slime layer in some) is also present in both gram positive and gram negative bacteria.
The main difference between gram positive and gram negative bacterial membrane is the presence of an extra outer membrane in gram negative bacteria. It consists of lipopolysaccharide, lipoproteins, proteins and phospholipids.
Outer membrane is not present in gram positive bacteria. The second difference is the presence of thick layer of cell wall in gram positive bacteria.

Which statement is TRUE? The membrane potential is negative on the cytoplasmic side and positive on the matrix side. The genomes of mitochondria don't range in size across species. The inner membrane is quite permeable because it contains mitochondrial porin, or VDAC (voltage-dependent anion channel). Mitochondria are semi-autonomous organelles, because mitochondria depend on the cell, and cells that contain mitochondria in turn depend on these organelles for oxidative phosphorylation. In bacteria, ATP-synthesizing complexes are located in the outer plasmatic membrane.
