Flashcards in Lecture 11: Integraton Of Metaboliism Deck (18):
T/F: The liver processes most, but not all, dietary amino acids.
- The kidney can process some as well
T/F: The presence of glucose-6-phosphatase makes the liver uniquely able to release glucose from glycogen into the bloodstream
- The muscles can do this only in a limited capacity
T/F: the liver synthesizes most of the urea produced in the body
- The kidney can do this as well
T/F: The liver normally fuels the body by releasing its fat stores during fasting
T/F: one of the livers major jobs is to provide fuels for the brain
What 3 things can glucose-6-phosphate make?
What 4 things can pyruvate make?
What is the role of the portal vein?
To carry nutrients from intestine to liver
What is the role of the lymphatic system in metabolism?
Carries lipids from intestine to liver
What is the role of adipose tissue in metabolism?
Synthesizes, stores and mobilizes TAGs
At what low blood sugar level can you start to see subtle neurological signs, hunger, sweating and trembling
At what low blood sugar level does lethargy, convulsions and coma occur?
What pathways are turned on in a well fed liver?
What pathways are on in well-fed adipose tissue?
What pathways are on in a well fed muscle?
What pathways are on in a fasting liver?
Ketone body synthesis
What pathways are turned on in fasting adipose tissue?
**no glucose uptake**
