According to Selye's theory of stress, during the condition of the stress, the body undergoes the general adaptation syndrome, which occurs in three stages. These three stages are fight or flight, resistance reaction, and exhaustion.
The flight or fight reaction is stimulated by the hypothalamus. It results in the excitement of the sympathetic division of the autonomic nervous system. The resistance reaction is caused by the hormones released by the hypothalamus; this is long lasting and provides ATP (adenosine triphosphate) molecules for the counter reaction to the stress.
As the result of use of ATP and other energy resource from body during the resistance reaction, the body becomes deprived of energy. This causes the exhaustion in the body.
So, the resistance phase of the stress expands a considerable amount of energy, which causes exhaustion.

Explanation:
Answer:
Palmitic acid
Explanation:
Intake of palmitic acid is associated with atrial fibrillation.
Palmitic acid - is a saturated long-chain fatty acid and a straight chain saturated fatty acid with a 16-carbon backbone. Palmitic acid is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat. It is a conjugate acid of a hexadecanoate.
Hexadecanoate - is a long-chain fatty acid anion that is the conjugate base of hexadecanoic acid (palmitic acid).
Answer:
The correct answer is option c). "Defective enzymes result in the accumulation of potentially toxic substances".
Explanation:
Lysosomal storage diseases (LSDs) are a group of rare metabolic disorders that have a genetic influence and are, most of time, autosomal recessively inherited. The molecular basis of the diseases are an accumulation of potentially toxic substances due to the presence of defective enzymes. In fact, LSDs are often triggered by a single defective enzyme that is required for lipids metabolism.
Answer:
The cell's proteins are first manufactured in the ribosomes. The polypeptide chains then enter the lumen of the Rough Endoplasmic Reticulum where they are properly folded with the help of chaperones and modified to achieve their desired shape which relates to their function. The proteins also undergo quality control in the RER, These proteins are then transported by vesicles, budding out of the trans side of the RER, and transported to the cis side of the Golgi apparatus. In the Golgi bodies, the proteins undergo further post-translational modification and packaging. Vesicles carrying the final proteins then bud off of the trans side of the Golgi apparatus and transport the protein to the cell membrane where they secreted them.
