The Hemoglobin subunits use a histidine amino acid to hold on to the heme group needed to chelate oxygen. You discover a new mutation in the Alpha-globin gene that causes it to code for a glycine instead of a histidine. These amino acids are very chemically different.
Hypothesize how this mutation might affect oxygen transport.
What is the specific role of oxygen in most cells?
Which among the following is the correct sequence of cellular respiration?

- Hello, May I get help on this question very soon please? I do not understand it. Question: You encounter a human-like extraterrestrial at the gym, which is remarkable for numerous reasons! And the best news is that they are as excited to learn about your human physiology as you are to learn about their extraterrestrial physiology. Because you're so excited about respiratory physiology right now, you start looking at how their oxygen-binding molecule ("xenoglobin"; equivalent of hemoglobin) changes in its oxygen saturation with different partial pressures of O2. You know that, at rest, our human hemoglobin is 100% saturated near the alveoli and 80% saturated after passing through the systemic capillaries and moving back into the veins. By contrast, your new extraterrestrial friend's xenoglobin molecule is 100% saturated near their alveoli and 60% saturated after passing through their systemic capillaries and moving back into the veins. What does this tell you about how our…arrow_forwardOn the very first page of this tutorial, we talked about the circulatory and respiratory systems being related. Now we're going to combine these into one process. Instead of following oxygen going into the body, we are going to trace the route that carbon dioxide takes on its way out of the body. The carbon dioxide is produced in the cell during cellular respiration. Starting at the organelle where this process takes place, find the route a molecule takes from the cell to the heart. right atrium vena cava 3 | interstitial fluid cytoplasm of cell 5 | right ventricle 6 vein 7 | capillary 8 E mitochondria :::: 4.arrow_forward#1) As electrons move through the mitochondrial space? A) water is oxidized B) the PH of the intermembrane space decreases C) they will no longer be able to perform anaerobic respiration #2) A child is born with a rare disease in which mitochondria are missing from skeletal muscle cells. However, the muscles still function. Phisicans find what? A) the muscles contain large amounts of carbon dioxide following even mild physical exercise B) the muscle cells cannot split glucose to pyruvate C) the muscles require extremly high levels of oxygen to function #3) Bacteria that are unable to survive in the presence of oxygen are called? A) obligate anaerobes B) aerotolerant anaerobes C) facultative anaerobes #4) A friend tells you that he is going on a low-carb diet to lose weight because he thinks that carbs contain more energy than fats or protein.
