skeletal, cardiac, and smooth
<span>The first law of thermodynamics is follows the quantity dQ = dW + dU where Q is the heat flow, W is the work and U is the internal energy. Only the internal energy is a state function where it means that it does not follow a specific path to arrive at a certain number. Whereas the work and heat are not state functions and they follow a specific path or process in order to arrive at a certain number. An example would be if y</span>ou are given 2,380 J of energy to do work as 12,900 J and you are to find the internal energy. Apply the equation above:
Q = U + W
2,380 J = U + 12,900 J
U = 15,280J.
Answer:
Aspirin works by inhibiting the production of prostaglandins. Aspirin inhibits the formation of prostaglandins by combining with the COX enzymes. Prostaglandins function as messenger molecules to monitor different physiological procedures in distinct regions of the body. One of the prime activities of prostaglandins is to stimulate inflammation and pain.
Prostaglandins are also the essential controller of platelet aggregation. By changing the COX enzymes inside the platelets, aspirin makes platelets to lose the stickiness, which is required to instigate clotting of blood.
There are two forms of cyclooxygenase, that is, COX-1 and COX-2. COX-1 generates prostaglandins and COX-2 mediates pain and swelling in response to tissue injury. Aspirin prevents both COX-1 and COX-2 functioning, while COX-2 is the therapeutic target of the drug.
However, it is the association of aspirin with COX-1 in the gastrointestinal tract, which results in the unwanted side effects of the drug. COX-1 is required to sustain a thick lining of the stomach. As aspirin inhibits the COX-1 enzyme, thus, the continuous use of the drug can result in the thinning of mucus, which safeguards the stomach from gastric juices.
In such cases, stomach bleeding, ulcers, and in certain situations perforation of the stomach can take place. Therefore, aspirin exhibits both bad and good effects.
The theory would be endosymbiont theory. It was developed on the idea that some eukaryotic organelles come from prokaryotic organisms. It is also known as symbiogenesis. This theory says that these organelles were first from prokaryotic cells that is living inside a host cell.
