The use of food for energy at the cellular level requires oxygen to support a controlled combustion process that produces energy molecules of adenosine triphosphate (ATP), which are used in all body processes for energy (see Figure 18-2).
The answer is (A) virus. In the medical field, it's considered non-living.
Answer:
Generally, aquaporins are found in the membranes of plants and also in the membranes of animals. It is a transporter, which takes part in mediating or regulating the flux of water across the membranes. A cell expresses the aquaporin protein due to many factors:
1. They function as sensors of gradients in turgor pressure and osmotic potential.
2. Aquaporins can assist in regulating and maintaining water permeability in response to different stresses like salt, drought, chilling, and others as water can move at a much greater speed through aquaporins.
3. Aquaporins can help in the movements of carbon dioxide, H2O2, NH3 through the plasma membrane briskly. Thus, the expression of aquaporin is essential for various species.
