Answer: Neurons

The most famous brain cell, the neuron, has been actively studied for over a century. There are still quite a few mysteries in neurons, but  scientists still know how neurons fire, react to which chemicals, and express which genes. Microglia, on the other hand, are slowly gaining attention. In short, the region is ripe for discovery, and  exciting microglial papers may appear one after another in the coming years and decades.

After strenuous exercise sore muscles can occur because of?
Anna007 [38]

Answer:

The correct answer is C. A buildup of lactic acid in the tissues.

Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.

Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.

Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.

This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.

In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.

Diagram found elsewhere attached

Answer:

Clockwise from bottom

3. formation of mRNA in the nucleus

6. secretion of hormone  by tissue

4. initiation of DNA  replication because  of a signal given  by the hormone

2. synthesis of protein  molecule by mRNA  and tRNA

1. secretion of protein  by the cell

5. binding of the  hormone molecule  with its receptor  of the cell

Explanation:

The tissue in the top left releases a hormone. For example, a steroid hormone such as estrogen, which can impact gene expression at the level of transcription. This hormone then travels to a different cell to carry out its function. The hormone is able to enter the cell and binds receptors which recognise it. In this case, these receptors are present in the nuclear envelope. When the hormone has bound the receptor, it initiates a signalling cascade that the cell responds to.

In this case, the effect of the signal from the hormone is to initiate DNA replication. This is a common effect of hormones such as growth factors that signal the cells to proliferate.

The initiation of the signalling can  also affect how genes are expressed. In this case, an mRNA is produced in the nucleus, which is created as a result of transcription. This mRNA molecule then moves to the cytoplasm, where it becomes translated into a polypeptide sequence at a ribosome, with the help from transfer RNAs (tRNAs).

This polypeptide forms a mature protein by progressive folding and potential modifications, and is released by the cell to perform its functions.
