What is the most important distinction between the membrane transporters known as channel proteins and those known as carrier pr
-Dominant- [34]

Answer:

Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.

Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.

Explanation:

Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.  

Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.

Where is over 95% of incoming ultraviolent radiation absorbed
zheka24 [161]

Answer:

Over 95% of incoming ultraviolet radiation is absorbed in :

A. The Stratosphere.

Explanation:

  • Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
  • This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
  • The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
  • During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
  • Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.
