9.2: glycolysis harvests chemical energy by oxidizing glucose to pyruvate

what does glycoslysis do

breaks down glucose into two molecules of pyruvate

how many carbons does glucose have

6 carbon sugar

how many carbons in pyruvate

3 carbon sugar

does glycolysis require O2

Glycolysis occurs whether of not O2 is present

where does glycolysis occur

in the cytoplasm

what are the two major phases of glycolysis

energy investment phase and energy payoff phase

what happens in the energy investment phase

2 ATP are used

what happens in energy payoff phase

4 ATP are made

what enzyme uses up the ATP in the energy investment phase

1 by hexokinase and 1 phosphofructokinase

what enzyme makes the ATP in the energy payoff phase

2 by phosphoglycerokinase and 2 by pyruvate kinase

what is the net of ATP molecules made in glycolysis

net of 2 ATP molecules are produced

what are the products of glycolysis from one molecule of glucose

2 ATP, 2 NADH+ 2H+, 2 pyruvate+ 2 H2O
