Group 11: Carbohydrate Metabolism Flashcards
A metabolic pathway in which the breakdown of a glucose molecule into 2 pyruvate and ATP
Glycolysis
Glycolysis is a ________ process.
Catabolic
What are the 6 metabolic pathways.
- Glycogenesis
- Glycolysis
- Gluconeogenesis
- Glycogenolysis
- Kreb’s Cycle
- Hexose Monophosphate Shunt
A metabolic pathway in which glucose is synthesized from non-carbohydrate materials.
Gluconeogenesis
A metabolic pathway in which glycogen is synthesized from glucose-6 phosphate
Glycogenesis
A metabolic pathway by which glucose-6 phosphate is produced from glycogen.
Glycogenolysis
Kreb’s Cycle is also known as
- Tricarboxylic Acid Cycle
- Citric Acid Cycle
What is the goal of Carbohydrate Metabolism
