The biological levels of organization start with the atom, which is the smallest unit of matter. Take two or more of the most fundamental units, atoms, to form molecules. Molecules that are biologically significant are called macromolecules. One example of a macromolecule is deoxyribonucleic acid (DNA). DNA contains the basis for the structure and functions of all living organisms. The succeeding levels of organization of living things are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and the biosphere.

1 out of 5 is 1/5.
Divide that and you get .20, which is 20%, so that is your answer, 20% fat.
Answer:
The best answers to your question, as per the immense amount of research on the topic, would be: The peptides that you would expect to find in the polypeptide that will eventually fold to become an ion channel protein, would be: 1. A signal-anchor peptide, 2. an internal signal peptide and an amino-terminal signal peptide.
Explanation:
Ion channels are transmembrane proteins whose main purpose is to serve as pathways through which different ions, like potassium, or sodium, can cross from both the inside and outside of the cell as it may be required in different circumstances. These proteins, unlike many others, are first translated from genetic material in the cytosol, and then, thanks to signaling sequences on their chain, they will be taken to the ER and Golgi apparatus, where the rest of the translation and the final packaging will be arranged, so that they may be shipped towards their destination, which is the plasma membrane. These proteins, because of their function, need to have a signal-anchor peptide, an internal signal peptide which will direct them to the ER for final assembly and packaging and an amino-terminal signal peptide.
