What organic molecule accumulates when oxygen debt occurs?
Lactic acid accumulates when oxygen debt occurs due to anaerobic metabolism in muscles. This buildup leads to muscle fatigue and soreness.
How is melanin produced and what is its function?
Melanin is a substance that is present in skin, hair, feathers, eyes, and scales of animals and humans that give these features their natural color. Melanin is produced as a metabolic process which occurs in amino acids in the body. Cells responsible for producing melanin are called melanocytes.
What is a sustained muscle contraction?
Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction. It is called a tetanic contraction.
How does melanin typically respond to ultraviolet radiation?
Melanin serves as a shield against UV exposure, which comes in the form of a tan that occurs when melanin pigments enlarge in response to UV radiation. By doing this, the skin helps to prevent sunburn damage, which can lead to cancerous melanoma.
Which foods are rich in melanin?
fruit, chocolate, coffee, truffles, wine...........
The tanning effect that occurs when a person is exposed to the sun is exposed to the sun is somewhat protective due to?
Increased production of melanin.
What is a pseudocyst?
This occurs when dead pancreatic tissue, blood, white blood cells, enzymes, and fluid that has leaked from the circulatory system accumulates.
What occurs where continental slope levels off and sediment accumulates?
A continental rise forms where the continental slope levels off, and sediment accumulates due to gravity transporting sediments downslope from the slope above. This is a gentle accumulation of sediments deposited by turbidity currents, rivers, and other geological processes at the base of the slope.
Where does scarlet fever occur most often?
It occurs most often around the throat where you can see red patches.
Which creature has patches of red on his rear-end?
The Male Mandrill has patches of red on his rear-end during mating season. Mating season lasts from June to October and only occurs in the Alpha males.
What substance accumulates in cell as a result anaerobic metabolism?
Lactic acid accumulates in cells as a result of anaerobic metabolism. This occurs when cells do not have enough oxygen to produce energy through aerobic respiration, and instead rely on anaerobic glycolysis to generate ATP.
What is ocular albinism?
Ocular Albinism is a type of albinism that affects mostly vision. It commonly comes with the lack of melanin in the skin that occurs in regular albinism.
