Match the following descriptions during the fed state to the proper part of the body
Takes in and uses glucose almost exclusively and burns it all the way down to water and CO2
Brain
Uses glucose but doesn't have mitocondria and burns it to pyruvate before converting it to lactate
Red blood cells
Uses glucose only after insulin stimulation and GLUT 4 activation. Burns all the way down to CO2 aerobically or lactate anerobically
Muscles
Uses glucose only after insulin stimulation and GLUT 4 activation. Glucose is turned into glycerol and then TGs
Adipose
Glucose can an enter and leave freely and only used when insulin is high. Stores excess glucose as glycogen
Liver
Which of the following store glycogen (SATA)
Muscles
Liver
Red blood cells
brain
Adipose
Match the following descriptions during the fasting state to the proper part of the body
Release glycerol and FA
Adipose
Use glucose making lactate which is sent to liver
Red blood cells
Primary consumer of glucose and breaks it down to CO2 and ATP
Brain
Uses keytone bodies from the liver and releases proteins via amino acids back to the liver
Muscle
Provides glucose to the brain and turns FAs into keytone bodies
Liver
During the starvation state keytone bodies can be taken up by the brain; however, it is not preferred due to being highly basic
True
False
