Location is everything 2. Proteins that span biological membranes often contain a helices. Given that the insides of membranes are highly hydrophobic (Section 12.2), pre- dict what type of amino acids would be in such an a helix? Why is an a helix particularly suited to existence in the hydrophobic environment of the interior of a membrane?

The amino acids plays an important role as they are the monomers of the protein. Proteins are present inside the cell membrane and transporters also require protein.

The hydrophobic amino acids will be present in the interior of the membrane as the cell membrane's interior is hydrophobic in nature. These helix is suitable carbonyl oxygen and amide hydrogen atoms plays important role in the peptide backbone formation and forms intrachain hydrogen bonding. The polar molecules will also get stabilize in the non polar hydrophobic environment.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
