Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places

essential for monitoring and maintaining a relatively constant level of glucose in the bloodstream‚ hence the liver is involved in glycogen breakdown and synthesis because these pathways allow the liver to remove glucose from the bloodstream for glycogen synthesis when blood glucose is high and to release glucose into the bloodstream from glycogen breakdown when blood glucose levels are too low. Glycogen provides an additional source of glucose besides that produced through gluconeogenesis which
