Glycolysis And Metabolism Flashcards
What is metabolism?
The creation of energy and building blocks for an organism
What is glycolysis?
The process of turning glucose to pyruvate via oxidation
What is digestion?
Where food and macromolecules are broken down
Where does digestion occur? (3)
Mouth, stomach and intestine
Where does absorption of food mainly occur?
The small intestine
Does glycolysis require oxygen?
No
Why are the intermediates of glycolysis phosphorylated? (3)
They cannot traverse the cell membrane, necessary to form the substrate enzyme complex, necessary to phosphorylate ADP yielding a net gain of ATP
What is the net yield of ATP when one mol of glucose is converted to pyruvate via glycolysis?
2 consumed + 4 generated = 2ATP (net)
What is the fate of pyruvate in yeast?
It gets converted to ethanol
What is the fate of pyruvate in skeletal muscle cells?
It gets converted to lactate
