Answer:
The events of protein synthesis are simple- First of all, protein synthesis is the process for which cells make proteins. Protein synthesis occurs in only two stages, transcription and translation.
Transcription-
Transcription is the transfer of genetic instructions in DNA and mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Translation-
Translation occurs at the ribosome, which consists of rRNA and proteins. During translation, the genetic code in mRNA is read and is used to make protein.
Explanation:
The two processes (transcription and translation ) are pretty much summed up by the 'central dogma of molecular biology' which goes- DNA → RNA → Protein.
Answer:
When a substrate is added in water, the enzyme will cause the substrate to dissolve in water. Increase in temperature will cause better functioning of the enzyme and more solute to be dissolved until an optimum temperature. Optimum temperature can be described as the temperature at which the activity of the enzyme is highest.
After optimum temperature is reached, the enzyme will get denatured and the substrate will no longer be able to dissolve in water.
Answer:
Norepinephrine
Explanation:
Nerve cells and circulating hormones are the one responsible for vasoconstriction of the vessel walls, as they do not enter the tunica media of the blood vessel, the nerves do not synapse directly on the smooth muscle cells. Instead, they release the neurotransmitter, norepinephrine, which diffuses into the media and acts on the nearby smooth muscle cells, which result in contraction of the entire muscle cell layer and thus reducing the radius of the vessel lumen.
The answer is diffusion.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
Answer:
Explanation:
In this lesson we will learn the three basic parts of all cells. Cells have something called a cell membrane, a nucleus, and cytoplasm.
