Glycolysis is the first step in cellular respiration. Which option best summarizes the process?(1 point)
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
anaerobic; 6-carbon glucose forms two 3-carbon ADP; forms a net total of 4 ATP
aerobic; 6-carbon glucose forms four 3-carbon ADP; 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
anaerobic; 6-carbon glucose forms two 3-carbon ADP; forms a net total of 4 ATP
aerobic; 6-carbon glucose forms four 3-carbon ADP; forms a net total of 3 ATP
Glycolysis is an anaerobic process in which a 6-carbon glucose molecule is broken down into two 3-carbon pyruvate molecules. It forms a net total of 2 ATP. Therefore, the correct option is:
anaerobic; 6-carbon glucose forms two 3-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?(1 point)
6 NADH, 2 ATP, 4 CO 2 , and 2 FADH 2
net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
net 1 NADH, 1 ATP, 2 CO 2 , 1 FADH 2
net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
6 NADH, 2 ATP, 4 CO 2 , and 2 FADH 2
net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
net 1 NADH, 1 ATP, 2 CO 2 , 1 FADH 2
net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
The correct products of the Krebs cycle after 1 molecule of glucose goes through it are:
6 NADH, 2 ATP, 4 CO2, and 2 FADH2
6 NADH, 2 ATP, 4 CO2, and 2 FADH2
Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They accept electrons in order to power the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
They accept electrons in order to power the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they donate electrons to the chain.
