The option that best summarizes the process of glycolysis is:
anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP.
Glycolysis does not require oxygen (anaerobic), breaks down one 6-carbon glucose molecule into two 3-carbon pyruvate molecules, and produces a net gain of 2 ATP.

net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
The correct option that lists the products of the Krebs cycle after 1 molecule of glucose goes through it is:
6 NADH, 2 ATP, 4 CO2, and 2 FADH2.
During one turn of the Krebs cycle, each glucose molecule (which is converted to 2 pyruvate before entering the cycle) results in this production, as each pyruvate completes one cycle.

Responses
They move electrons to the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.

Responses
They move electrons to the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They accept electrons in order to power the electron transport chain.
The correct response is:
They move electrons to the electron transport chain.
NADH and FADH2 are essential because they act as electron carriers, transferring high-energy electrons to the electron transport chain, which is crucial for the production of ATP during cellular respiration.
