Explain ways in which the alveoli are adapted to increase the<br>efficiency of gas exchange.​
KonstantinChe [14]

Answer:

Adaptations of the alveoli:

Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.

You are a carbon atom. You are having a wonderful (or awful) life, bonded to
iogann1982 [59]

A metabolic manner referred to as cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.

Four steps of Cellular Respiration

  1. Glycolysis. During glycolysis, the six-carbon sugar glucose is going thru some of chemical changes. In the end, it's miles converted into molecules of pyruvate, an natural molecule with 3 carbons.
  2. Oxidation of pyruvate. The mitochondrial matrix, the inner most compartment of the mitochondria, gets every pyruvate produced for the duration of glycolysis.
  3. Cycle of citric acid. A four-carbon molecule and the created acetyl CoA engage and go through a chain of events, in the end renewing the preliminary four-carbon molecule.
  4. Phosphorylation through oxidation A gradient is created as protons are pumped out of the matrix as electrons flow down the chain, liberating power as they do so. Through the introduction of ATP through the enzyme ATP synthase, protons float returned into the matrix.

Chemical Energy: C6H12O6 6O2 → 6CO2 6H2O (in ATP)

According to the equation, oxygen (O2) and glucose (C6H12O6) react to provide carbon dioxide (CO2) and water (H2O), which releases power. Cellular respiratory is an cardio manner because oxygen is essential for it to occur.

Quadrilateral ABDE is a rectangle. DE = 4 in. and BD = 6 in.
cestrela7 [59]
If the rectangle ABDE is rotated about the line through CF, cylinder Y is created. The radius of a cylinder is: AB / 2 = 4 / 2 = 2 in. If the rectangle ABDE is rotated about the line through GH, cylinder Z is created. The radius of a cylinder is : DB / 2 = 6 / 2 = 3 in.The difference in the measures of the radii:r 2 - r 1 = 3 in. - 2 in. = 1 in.
Answer: The difference is 1 inch.
