–Answer catabolic

• glycolysis is the initial pathway for

–Answer carbohydrates

• glycolysis breaks down a glucose molecules and produces

–Answer

• pyruvate, 2 NADH, 2 ATP, 2 H+
• true or false

–Answer anaerobic fermentation requires oxygen –Answer false

• what does anaerobic fermentation produce?

–Answer lactic acid

• what is lactic acid needed for?

–Answer needed to repeat glycolysis if no oxygen is present

• is oxygen is present, glycolysis is followed by

–Answer acetyl-CoA formation

• true or false

–Answer acetyl-CoA formation does not require oxygen 2 / 3

SUBSCRIBE

–Answer false

• where does acetyl-CoA formation occurs?

–Answer matrix

• pyruvates from glycolysis travel from the cytosol to the

–Answer matrix in the mitochondria

• the pyruvate gets converted into acetyl-CoA which results in the produc- tion of

–Answer

2 CO2, 2 NADH, 2 H+

• true or false

–Answer oxygen is required for the krebs cycle –Answer true

• where does the krebs cycle occur

–Answer matrix of the mitochondria

• acetyl-CoA from step 2 enters the krebs cycle and produces

–Answer

2 ATP, 4 CO2, 6 NADH, 6 H+, 2 FADH

• 6 NADH, H+, 2 FADH travel to the inner mitochondrial membranes and enters

–Answer electron transport chain

• true or false

–Answer oxygen is not required for the electron transport chain –Answer false
