Term
Glycolysis
Definition
Splitting of glucose to make 2 pyruvate molecules with gain of 2 ATP
Term
Takes place in cytoplasm of cell
Definition
Location of glycolysis
Term
First step in glycolysis
Definition
Phosphorylation of glucose with hydrolysis of ATP
Term
Reason glusose is phosphorylated
Definition
Makes glucose more reactive
Term
Second step in glycolysis
Definition
Second phosphorylation to produce hexose bisphosphate with hydrolysis of ATP
Term
Result of breakdown of hexose bisphosphate
Definition
Two molecules of triose phosphate
Term
Direct formation of ATP from triose phosphate
Definition
Substrate level phosphorylation
Term
NAD
Definition
Hydrogen carrier that acts as a co-enzyme in glycolysis
Term
Constituents of NAD
Definition
Nicotinamide, two phosphates, two ribose and adenine
Term
Reduced NAD
Definition
What NAD becomes after accepting two hydrogen atoms
