Flashcards
Hemoglobin (Hb)
Hemoglobin (Hb)
A protein in red blood cells that carries oxygen throughout the body. Hb is made up of four polypeptide chains (globin) and four heme groups, each containing an iron atom that binds to oxygen.
TCA Cycle
TCA Cycle
A series of enzymatic reactions that occur in the mitochondria, responsible for the oxidation of acetyl-CoA to carbon dioxide, generating ATP (energy) and electron carriers (NADH and FADH2).
Gluconeogenesis
Gluconeogenesis
The metabolic process of synthesizing glucose from non-carbohydrate sources like amino acids, lactate, or glycerol. It occurs primarily in the liver to maintain blood glucose levels during fasting.
