Question
Chapter 12.4, Problem 1MQ
Summary Introduction
The three domains of life present on earth are Bacteria, Archaea and Eukarya. Carl Woese in 1970 suggested that the genomic sequence of rRNA (ribosomal ribonucleic acid) molecules and its genome is used to understand the evolutionary relationship among organisms. He found that the small subunit rRNA sequences (SSU rRNA) of many microorganisms are different from the sequences of SSU rRNA molecules of Bacteria and Eukarya. Woese named this new prokaryotic organism as Archaea.

- ✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.
