<prompt> Which of the following pathway occurs paly in mitochondria and paly in cytosol?GlycolysisKrebs cycleKetogenesisUrea cycle  <response>: In mammals, the urea cycle takes place primarily in the liver, and to a lesser extent in the kidney. The urea cycle consists of five reactions: two mitochondrial and three cytosolic. The cycle conves two amino groups, one from NH4 and one from Asp, and a carbon atom from HCO3-, to the relatively nontoxic excretion product urea at the cost of four high-energy phosphate bonds 3 ATP hydrolyzed to 2 ADP and one AMP. Ornithine is the carrier of these carbon and nitrogen atoms.Ref: DM Vasudevan, 7th edition, page no: 196,203,226
