(30 points) In the article "Unification of Protein Abundance Datasets Yields a Quantitative Saccharomyces cerevisiae Proteome" by Ho et al. Cell Systems 6, 192-205 (2018), the authors show how to estimate the number of protein molecules in a typical yeast cell. The answer they get is about 42,000,000. A yeast cell has a volume of 42m3. If human cells have a protein density similar to yeast cells, how many proteins are there in a human cell
