Answer:
Protein synthesis
Explanation:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation.
Heterogenous Mixture is the correct answer ! Hope it helps
Answer:
I don't know
Explanation:
can you help me with this question The following lines from Frost's "The Road Not Taken" indicate what about the Speaker? Line 2: And sorry I could not travel both Line 3: And be one traveler long I stood A. The spaaker is waiting for someone TOT a long time ("long I stood"). B The speaker is traveling by himself- just "one traveler." C. The speaker is sorry he can't travel both roads
The right answer is: voltage-gated channels
Ionic channels are membrane proteins that allow the selective passage of the cell membrane by ions (Na +, Ca2 +, K +, Cl-, ...) following the electrochemical gradients. They play a vital role in cellular excitability, triggering and propagation of action potential. They intervene in the coupling excitation-contraction and excitation-secretion. Ion channel selectivity is based on the adequacy of ion size and charges with the structure and amino acid sequence of the channels.
Among these channels, there are voltage-gated channels.
These are ion channels whose opening is activated by the membrane potential.
These dependent volumetric channels are characterized:
- by the selectivity of the ions (Ca2 +, Na +, K +, Cl-, ...)
- by their conductance
- by their activation domain (significant depolarization to low)
- by their kinetics of inactivation (slow, fast or transient)
