True.
Ribosomes are organelles inside a cell made up of protein and ribosomal RNA (rRNA).
Ribosomes synthesize proteins by linking amino acids together. Some ribosomes float freely in the cytosol of a cell, while others bind to the endoplasmic reticulum.
Free ribosomes are those found floating freely in the cell cytosol. They mainly manufacture proteins needed for the cell's own use.
Bound ribosomes are found "bound" to the endoplasmic reticulum creating what is known as rough endoplasmic reticulum. Most of the proteins made by these bound ribosomes are transported outside the cell for use in other parts of the body.

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.
