24) Yes it can pass the membrane as it is lipid soluble.
25) Hydrophilic because phosphate is hydrophilic so regardless of its place it will always be hydrophilic.
26) Hydrophilic because it is inside the cell and inside the cell is hydrophilic.
27) Hydrophobic because fatty acid itself is hydrophobic.
24. Can a lipid soluble protein readily cross the cell membrane? a. Yes b. No 25....

BACKGROUND: Mycobacterium tuberculosis causes tuberculosis, one of the world’s deadliest diseases. It is an acid-fast bacillus that is 2-4 um in length and 0.2-0.5 um in width. How many weeks, days,& hours would it take to see a M.tuberculosis colony on solid media? Its generation time is listed in the reading (above). Assume that bacterial colonies are not visible to the naked eye unless they contain ≥ 2 millioncells. This species forms aggregates of 5 cells on average. Show your...
5.To gain entry, spikes of the SARS-CoV-2 bind to angiotensin-converting enzyme 2 (ACE2) found in epithelial cells especially of the respiratory and oral passageways. As such, these cells are susceptible to infection by SARS-CoV-2. ACE2 is a protein consisting of multiple alpha-helices that is embedded in, and spans, the membrane. What is this type of protein called, and what structure do the alpha helices represent? 6.Following binding of spike proteins to ACE2, SARS-CoV-2 likely gains entry into the cell either...
