Whether the data given below suggest the protective effect of lycopene against tobacco’s effect. The data are represented by the graph shown below: Introduction: Lycopene is a carotenoid pigment found in tomatoes, carrots, watermelons, and papayas. It is a good source of vitamin C and is a powerful antioxidant. It is assumed to impart benefits by protecting against different types of cancers.

Question

Dipal mitoylphosphatidylcholine is the major component of surfactant, or surface active agent (an amphipathic molecule), that is secreted into lung alveoli to reduce the surface tension of the primarily aqueous extracellular fluid of the alveolar epithelia. Alveoli, also referred to as alveolar sacs, are the functional units of respiration. Oxygen and carbon dioxide diffuse across the walls of alveolar sacs, which are one cell thick. The water on alveolar surfaces has a high surface tension because of the attractive forces between the molecules. If the water’s surface tension is not reduced, the alveolar sac tends to collapse, making breathing extremely difficult. If premature infants lack sufficient surfactant, they are likely to die of suffocation. This condition is called respiratory distress syndrome. Draw the structure of dipalmitoylphosphatidylcholine. Considering the general structural features of phospholipids, propose a reason why surfactant is effective in reducing surface…

After spending a day or more at high altitude (with an oxygen partial pressure of 75 torr), the concentration of 2,3- bisphosphoglycerate (2,3-BPG) in red blood cells increases. What effect would an increased concentration of 2,3-BPG have on the oxygen-binding curve for hemoglobin? Why would this adaptation be beneficial for functioning well at high altitude?

In carbon monoxide (CO) poisoning, CO binds to hemoglobin, therebydecreasing the uptake of O2 by hemoglobin. In addition, when CO bindsto hemoglobin, the oxygen-hemoglobin dissociation curve shifts to theleft. How does this shift affect the ability of tissues to get O2? Explain
