  1. Protein is an absolutely essential part of our diet. Without it, we would go into negative nitrogen balance.
  2. A good place to start might be to count carbon atoms and see whether any have been lost or added upon conversion to the products.
  3. https://www.statnews.com/2020/04/29/gilead-says-critical-study-of-covid-19-drug-shows-patients-are-responding-to-treatment/ Patients taking remdesivir recovered more quickly than those taking a placebo. Business Insider and CNN have stories.
  4. Muscle cells undergoing anaerobic consumption of glycogen produce more pyruvate than they can consume aerobically via the TCA cycle. The pyruvate is instead converted into pyruvate. Your second sentence implies that there is an additional way to make lactate, but there isn't.
  5. Are enzymes equally active at all pH values, or do they have an optimum pH? Does the balanced reaction produce/consume protons? The mechanism that you drew implies the answer. In other words if one used unbuffered water, would the pH of the water gradually change with time. With respect to why convert pyruvate into lactate, there are several ways to think about it. If a muscle cell did not, what would happen to the ratio of NAD to NADH within that cell?
  6. You might also ask which would pass through the plastic and which would not.
  7. John, If you are correct, then whoever made the drawing must have been smoking something.
  8. If you are looking for a basic reference book, you might find Fundamental Concepts of Bioinformatics by Krane and Raymer to be helpful, in that one of the authors is a biologist and the other a computer scientist. It is a bit out of date, but it is inexpensive.
  9. Something to bear in mind is that formal charges and oxidation numbers are both tools to help us keep track of electrons and charges. They make different assumptions about which atom owns the electrons.
  10. Please give us your thoughts first, and perhaps we can help. I would start by ruling out some choices.
  11. This topic really belongs in homework help. In that section, you may expect help but not answers. My hint is that you first make sure you have a solid grasp of ionic bonds and intermolecular forces.
  12. It might take me or someone else some time to find it, but I seem to recall reading somewhere that the connection between runner's high and endorphins has never been established.
  13. We are zooming, too. I am trying to learn how to use a Wacom Intuos, but it's the old dog/new tricks problem.
