Answer:
. Identify the process that triggers the initial surge of nitrogen excretion,
The reason for this is because of the gluconeogenesis ,(in the liver and cortex of the kidney) which make up for the reduction in glucose blood level, from rapid catabolism to glucose at the beginning of fasting, by breaking down protein to glucose in the liver. Therefore excess Nitrogen is produced as the byproducts of amino acids catabolism.
Physiologically the mammalian brain prefers the keto bodies supply from fatty acids catabolism from gluconeogenesis compare to protein. These water solube subtances cross the BBB to reach the brain the CNS substituting for glucose. Thus as more fatty acids is converted to ketobodies at faster rate, the brain gets adapted to this, and therefore catabolism of amino acids drops, hence Nitrogen concentration in the blood drops.
However, with exhaustion of Glycogen and fatty acid, catabolims of amino acids resumes. therefore, more amino acids are broken down, and Nitrogen build up in the Urine for excretion.
Explanation:
Answer:
true
Explanation:
convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
heat go up, cold go down. they cycle.
Oil Coal and Natural Gas are the fossil fuels the USA has the most reserves of. Given that only one of them is on the answers Coal is the correct answer.
Answer:
Negative feedback mechanism
Explanation:
Negative feedback mechanism occurs when the product or the output of a process inhibits the same process. When blood glucose level rises, body receptors stimulate beta cells in pancreas to release insulin. Insulin leads to uptake of glucose by cells, lowering the blood sugar levels. The lowered blood sugar level is again sensed by the receptors and they inhibit the secretion of insulin. Hence, insulin inhibits its own secretion by removing glucose from blood which makes it a negative feedback mechanism.
