a store of carbohydrates in the body
glycogen
is the process of storing excess glucose for use by the body at a later time
glycogenesis
breakdown of glycogen occurring in the liver when blood glucose levels drop
glycogenolysis
The process of making glucose (sugar) from its own breakdown products or from the breakdown products of lipids (fats) or proteins
gluconeogenesis
is the process of storing excess triglycerides for use by the body at a later time
lipogenesis
the breakdown of lipogenesis (fats and other lipids) by hydrolysis to release fatty acids.
lipolysis
occurs when an excess in protein is consumed, resulting in the removal of an amine group, which is then converted into ammonia and expelled via urination
deamination
the transfer of an amino group to a keto acid
transamination
the body uses Glucose for
energy
the body uses Glycogen for
When the body needs a quick boost of energy or when the body isn’t getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells (stored)
the body uses triglycerides for
fuel body movement, create heat and provide energy for body processes.
