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.

Anybody Please help ASAP!!!
crimeas [40]

Answer:

This is issued when a tornado is indicated by the WSR-88D radar or sighted by spotters; therefore, people in the affected area should seek safe shelter immediately. They can be issued without a Tornado Watch being already in effect. They are usually issued for a duration of around 30 minutes.

A Tornado Warning is issued by your local National Weather Service office (NWFO), see map below. It will include where the tornado was located and what towns will be in its path. If the tornado will affect the nearshore or coastal waters, it will be issued as the combined product--Tornado Warning and Special Marine Warning. If the thunderstorm which is causing the tornado is also producing torrential rains, this warning may also be combined with a Flash Flood Warning. If there is an ampersand (&) symbol at the bottom of the warning, it indicates that the warning was issued as a result of a severe weather report.

After it has been issued, the affected NWFO will followed it up periodically with Severe Weather Statements. These statements will contain updated information on the tornado and they will also let the public know when warning is no longer in effect.

Most drugs that inhibit the synthesis of the cell wall act by
lukranit [14]

Answer:

a. preventing the cross-linkage of NAM subunits

Explanation:

The bacterial cell wall is made of peptidoglycan which is a polymer of alternating  N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. The NAM residues  are crosslinked to impart additional strength to the cell wall.

Most of the antibiotics that target the cell wall synthesis in bacteria inhibit the enzyme of transpeptidation which in turn cross-links the NAM residues of the polysaccharide chains of the bacterial cell wall. Examples of these antibiotics include penicillins and cephalosporins.
