Question
Chapter 3.1, Problem 1TQ
Summary Introduction
To review:
The chemicals that are present in the greatest and the smallest number in the bacterial cell. Also reveal the reason behind the bacterial cell possessing 100 times the lipid molecules as compared to the strands of ribonucleic acid (RNA).
Introduction:
Â
Bacterial cells are prokaryotic cells that do not possess a membrane encircled nucleus and organelles. These cells consist of chromosomes and circular DNA (Deoxyribonucleic acid) along with ribosome, cytoplasm, and nucleoid. These cells are found in various shapes like cylindrical, minute spheres, filamentous chains, flagellated rods, and spiral threads. There are various intracellular components that are present inside the cell.

OA carbohydrate has a unique structure to assist chemical reactions, and a nucleic acid has a unique structure to assist diffusion across a plasma membrane.arrow_forwardYou are searching for life in extreme environments. You collect samples from two different settings: hot volcanic ash and a glacier. Luckily, you discover a new species of bacteria in one of your samples. However, you messed up and accidently forgot to label your samples, so you don’t know which environment it was from! You study the lipids from the membrane of the new bacterial species. You find that the membrane phospholipids contain a high amount of saturated fatty acids and fatty acids with long carbon chains. Was your bacterial isolate from the hot volcanic ash or the glacier? Explain why you picked that environment, using two pieces of evidence from the provided information about the bacteria’s membrane lipids to support your answer.arrow_forwardWhen phospholipids are carefully mixed with water they are observed to exhibit which of the following properties? a) Spontaneous organization into stable structures within the water environment, b) Orientation of the Phosphate parts of the molecule away from fatty acid (non-polar) environment of a bilayer, c) Hydrophilic orientation of the ionic section of the phospholipid molecules to the polar portions of the water molecules, d) All are true, e) None are true.arrow_forward
