Glucose metbaolism Flashcards
(8 cards)
What is metabolic homeostasis?
Maintaining optimal metabolite concentrations and manageing energy reserves
What is catabolism?
The degradative phase of metabolism; releases energy
What is anabolism?
The biosynthetic phase of metbaolism; requres energy
What are the mahor functions of glucose in the body?
Major energy substrate, especially for brain and RBCs
How is blood glucose maintained given only 10g in the bloodstream?
Through dietary intake, glycogen breakdown, and gluconeogenesis
What are the consequences of hypoglycemmia for the brain?
Impaired function due to inability to store or synthesise glucose
What is portein glycation?
Non-enzymatic modification of proteins by high glucose levels
What’s the difference between glycation and glycosylation?
Glycation is non-enzymatic; glycosylation is enzyme-mediated
