polet [3.4K]

ATPs are the power cell of a cell. Just like a cell, they need to be charged before they can deliver power.

<h3><u>Explanation:</u></h3>

ATP or the Adenosine Triphosphate is a complex molecule containing a Adenine nitrogen base, a ribose sugar and three phosphates being attached with each other in a chain. Adenosine Triphosphate is the power currency of a cell. It just acts like a rechargeable battery. The metabolic and physiological processes of a cell that needs energy, involves the hydrolysis of ATP into ADP and Pi which are Adenosine Diphosphate and Inorganic phosphate respectively.

Now the ATP is discharged and needs to be charged. So the ADPs are charged into ATPs by different processes of respiration  like Glycolysis, Kreb's Cycle, Electron Transport Chain etc.

Both the hydrolysis and the condensation of ATP makes the ATP cycle.

slit2 overexpression results in increased microvessel density and lesion size in mice with induced endometriosis.
solmaris [256]

The overexpression results in increased micro vessel density and lesion size in mice with induced endometriosis.

Endometriosis is a benign gynecological disorder.

  • it's far characterized through the ectopic presence of endometrial glands and stroma out of doors of the uterine hollow space and is carefully related to dysmenorrhea, pelvic pain, and subfertility.
  • In endometriosis, the involvement of vascular endothelial mobile growth issue (VEGF) and different angiogenic mediators has long been recognized endometriotic angiogenesis entails numerous pathways and the blockade of simply one single pathway won't effectively suppress Endometriosis
  • Slit is a secretory glycoprotein which include 3 members, Slit1, Slit2, and Slit3, and become at first found to be secreted repellents in axon steerage and neuronal migration It has been shown to be an endogenously available inhibitor of leukocyte chemotaxis.
  • receptor for Slit is the  protein Roundabout (ROBO), which currently includes 4 members (ROBO1-4)

Introns must be removed prior to translation of the mRNA. In addition, eukaryotic transcripts (mRNA) have to undergo two more st
Ivan

Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.

<h3>RNA processing:</h3>

1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).

2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.

3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.

4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.

The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.

If an atom has 15 electrons, how many electrons are in the n=1 energy level?
IRISSAK [1]

Answer:

In the n=1 energy level, the atom has 2 electrons

Explanation:

Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.

For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.

In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.

To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.
