Answer: c. 2 pyruvate molecules
Explanation:
Glycolysis is the first step it the cell respiration cycle. It turns one molecule of glucose into two molecules of pyruvate by a series of reactions catalyzed by different enzymes.
It starts by using 2 ATP to turn glucose into fructose-1,6-bisphosphate, which then divides in two and releases 4 ATP when it turns into two pyruvate molecules.
Thus glycolysis consumes 2 ATP and releases 4 ATP (giving a net gain of 2 ATP) and 2 pyruvate molecules.
Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle, while Eukaryotic cells contain membrane-bound organelles, including a nucleus.
Answer:
The correct answer is glycolysis, the citric acid cycle, and oxidative phosphorylation
Explanation:
Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.
In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.
In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.
So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.
