Glycolysis is the first step in cellular respiration. Which option best summarizes the process?
anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 4 ATP
aerobic; 6-carbon glucose forms four 3-carbon pyruvates; forms a net total of 3 ATP
aerobic; 6-carbon glucose forms three 2-carbon pyruvates; forms a net total of 2 ATP
anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP
The Krebs cycle forms many products. Which option lists the correct products of the Krebs cycle after 1 molecule of glucose goes through it?
net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
net 1 NADH, 1 ATP, 2 CO2, 1 FADH2
net 2 NADH, 2 ATP, 4 CO2, 2 FADH2
Why are NADH and FADH2 necessities in the electron transport chain?
They donate electrons.
They help break up CO2.
They pick up electrons.
They help form water.
