Early interphase is called the G1 phase of the cell cycle. G1 is the time during which a cell grows to its proper size by making more cytosol, the liquid inside a cell. An increase in cell size means the cell must make more protein and membranes. ... Cells that mature and never divide again stay in the G0 phase.
The correct answer is urea.
Urea is formed from the deamination (removal of amine group) of amino acids producing a highly toxic ammonia. Ammonia will then join carbamyl phosphate to form citrulline. Citrulline will then cycle through the urea cycle until it forms arginine. Arginine then will be broken down to ornithine and urea. Urea is excreted in the urine and ornithine is used to replenish citrulline.
