Which hormone uses a second messenger mechanism? testosterone estrogen norepinephrine cortisol none of these choices?
jeka94

<span>Norepinephrine uses the Second Messenger System, which means, cells signal to each other what molecules have been released that will trigger a physiological reaction. </span>

<span>
This phenomenon is activated after the ligand  (ion or molecule) is bonded to its receptor (protein molecule), creating a variation that causes a chain-reaction, that will finally activate the Second Messenger. The latter will activate intercellular molecules that will be able to control the cell’s activity. </span>

Identify the eukaryotic cellular locations of the fundamental processes that are involved in the central dogma of molecular biol
Papessa [141]

Answer:

See the answer below

Explanation:

The central dogma gives a description of how genetic information travels in biological cells from DNAs to proteins. DNAs are first transcribed into messenger RNAs in a process known as transcription and the resulting mRNAs are used in the synthesis of proteins in a process known as translation.

In eukaryotic cells, transcription process happens within the confines of the nucleus because the genetic material in the form of DNAs are always located in the nucleus. Thereafter, the mRNAs generated from transcription are transported to the cytoplasm of the cell where they become translated into proteins.

Hence;

  • <em>T</em><em>ranscription</em><em> happens in the </em><em>nucleus</em><em> of the cell.</em>
  • <em>Translation </em><em>happens in the </em><em>cytoplasm</em><em> of the cell.</em>

What is the function of NADPH and ATP in the Calvin cycle?
yuradex [85]

Answer:

The correct option is A. They provide the energy required to build high-energy sugars.

Explanation:

Calvin cycle can be described as the series of dark reactions of the process of photosynthesis.

During the Calvin cycle, carbon dioxide is reduced to glucose. The molecules of NADPH and ATP play an active role in this reaction to occur. The molecules of ATP serve as a source of energy. Whereas, the molecules of NADPH serve as a reducing agent. Electrons are added by NADPH so that carbon dioxide gets converted into glucose.
