Metabolism Flashcards
Utilizing compounds for the generation of energy
Catabolism
Utilization of energy to produce compounds
Anabolism
What is a major intermediate in several pathways of energy production?
Acetylene-CoA
Pentose Phosphate Pathway
Generates NADPH,
Generates 5 carbon sugars for nucleotides
Glycolysis
Glucose to pyruvate, important side products in some tissues (Glycerol-3-phosphate, 2,3-bisphosphoglycerate)
Gluconeogenisis
Synthesis of glucose from pyruvate (non-carb sources).
Restricted to the liver/kidney
Source from carbs in glycoproteins and ptoteoglycans
Glucose
Source of glucuronides
Glucose (very active in the liver). Makes poorly soluble compounds more soluble in aqueous environment, thus more easily extracted. Active on bilirubin and drug substrates.
What is Acetyl-CoA a substrate for?
TCA cycle, Lipogenesis, Cholesterol synthesis, Ketone bodies
What are the two end fates for amino acids?
Elimination as urea, reutilization to form another amino acid
What is the main source of nitrogen for the body?
Amino Acids
Where does gluconeogenesis occur?
Kidneys/Liver
What type of metabolism can RBCs not utilize?
Aerobic carbohydrate metabolism
In what areas of the body is glycogen mainly found?
Muscle and liver
In what areas of the body are triglycerides mainly found?
Adipose tissue
