How is oxygen and carbon dioxide transported in human beings
Oxygen have low solubility in body fluids and cannot move fast to different parts of the body by diffusion. So humans and other animal have developed a specific mechanism for this. Here oxygen diffuses fast in lungs due to high surface area.
What are the different ways in which glucose is oxidized to provide energy in various organisms
Every organism uses glucose as a source of energy. This process is called respiration During this process glucose in broken down into pyruvate. Which later is converted into other molecules.
What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration
Oxygen content in water is lesser as oxygen is not highly soluble in water. While the concentration of oxygen is high in atmosphere. As a result fish respire at higher rate than terrestrial animals.
