glycolysis Flashcards
(20 cards)
What is glycolysis?
The first stage and involves the splitting of one glucose into two pyruvate molecules.
Where does glycolysis occur?
The cytoplasm and is anaerobic.
What does glucose get converted into first?
Glucose phosphate.
How many carbons does glucose phosphate have?
6.
What does glycolysis require?
ATP.
Why does glucose need to be phosphorylated?
To make it more reactive.
What is glucose phosphate converted into?
2x triose phosphate.
How many carbons does triose phosphate have?
3.
What is required for the conversion of glucose phosphate?
ATP.
What is triose phosphate converted into?
2x pyruvate.
How many carbons are there in pyruvate?
3.
What is required for the conversion of triose phosphate?
2 oxidised NAD.
What is produced during glycolysis?
4x ATP and 2 reduced NAD.
What is the production of ATP from?
Substrate level phosphorylation.
What type of reaction is glycolysis?
Oxidation of triose phosphate.
What is the purpose of NAD?
Coenzyme and transports hydrogens to the electron transport chain in oxidative phosphorylation.
What is the net gain of ATP in glycolysis?
2 ATP.
Where is the pyruvate transported to?
The mitochondria.
What is the type of transport for pyruvate?
Active transport.
What is needed for respiration to continue in the mitochondria?
Oxygen.
