Why is facilitated diffusion used to transport bicarbonate across a membrane?
Diffusion of solutes through transport proteins in the plasma membrane is referred to as facilitated diffusion. Passive transport is a subset of facilitated diffusion. Because the solution is traveling down the concentration gradient, assisted diffusion is still passive transport even when it incorporates transport proteins.
We employ assisted diffusion because...
Therefore, polar and charged molecules including ions, amino acids, nucleosides, and carbohydrates can traverse the plasma membrane due to facilitated diffusion. Carrier proteins and channel proteins are the two main groups of proteins that mediate assisted diffusion.
Even though ions are small molecules, the charge they carry prevents them from diffusing through the lipid bilayer of biological membranes. As a result, assisted diffusion is used to transfer them along their gradient of concentration.

Would the atmospheric concentration of oxygen increase or decrease after the bubonic plague?
Answer:The Great Oxidation of Earth’s atmosphere about 2.3 billion years ago began a series of geochemical events leading to elevated oxygen levels for the next 200 million years, with a collapse to much lower levels as these events played their course. This sequence of events is represented in rocks from the Republic of Gabon. We show oxygenation of the deep oceans when oxygen levels were likely their highest. By 2.08 billion years ago, however, oxygen dropped to levels possibly as low as any time in the last 2.3 billion years. These fluctuations can be explained as a direct consequence of the initial oxygenation of the atmosphere during the Great Oxidation Event.

dipalmitoylphosphat Contains dipalmitoylphosphatidylcholine been added to surfactant? Idylcholine, sometimes referred to as dppc, is a lung surfactant component that works to lower surface tension.
The cohesive state that develops at a liquid-liquid or liquid-gas contact is referred to as surface tension. This happens in the lungs at the point where the alveolar membrane and the airway meet. Alveoli are drawn together as a result of increased cohesion caused by increased surface tension.
How does surface tension affect lung compliance?Surfactant synthesis lowers surface tension within the alveoli to prevent collapse. Surface tension can be reduced to more readily obtain compliance. Together, the chest wall and lungs make up the combined compliance system.
Dipalmitoylphosphatidylcholine, a phospholipid particularly, makes up the majority of the lipid content and is what gives surfactant its biophysical properties.
Water has a high surface tension due to the strong cohesive interactions between its molecules. Surfactants disrupt these interactions as they absorb.
