Taking one molecule of glucose through glycolysis, pyruvate oxidation, and the Krebs cycle generates: a) 6 CO 2 , 8 NADH, 2 FADH 2 and 4 ATP. b) 6 CO 2 , 8 NADH, 1 FADH 2 and 2 ATP. c) 6 CO 2 , 10 NADH, 2 FADH 2 and 4 ATP. d) 6 CO 2 , 10 NADH, 2 FADH 2 and 2 ATP.

Okay, everyone. Taking one molecule of glucose through glycolysis, pyruvate oxidation, and the Krebs cycle creates what? Okay. So, basically, they're asking us what are the total products of the first three steps of aerobic cellular respiration? So let's start with glycolysis. So what is made in glycolysis? Remember that you're going to make 2 NADH and you're gonna make 2 net ATP. Now, you also make 2 pyruvate molecules, but technically, those 2 pyruvate molecules are consumed by the next step, which is going to be Pyruvate Oxidation. So, what is created in Pyruvate Oxidation? Remember that 2 NADH are also going to be made in this step And also 2 c o two molecules are gonna be made. No ATP is made and 2 acetyl co a molecules are made, but then they are going to be consumed in the very next step, which is the krebs cycle. And remember that the krebs cycle is going to make a total of how many NADH? It's going to make 6 NADH. Let me write that in the correct color. It's gonna make 6 NADH. It is also going to have another electron carrier. It's gonna make 2 f a d h two's. It's also going to make ATP, but it's only gonna make 2 ATP. And then finally, it is going to make 4 c o two molecules. Okay. Now, those are going to be all of the products of the different stages of cellular respiration, except for the electron transport chain. So just the first three steps. What do we have? So in total, we are going to have we are going to have 10 NADH molecules. We are gonna have 2 FADH 2 molecules. We're gonna have 4 ATP molecules and we are going to have 6 c o 2 molecules. That is going to be the major products of the first three steps. And the only answer here that has all of the right numbers and all of the right products is answer choice c. Okay, everyone. Let's move on to our next video.

Verified step by step guidance

Understand the process: Glycolysis, pyruvate oxidation, and the Krebs cycle are stages of cellular respiration that convert glucose into energy, carbon dioxide, and electron carriers.

Glycolysis: This process occurs in the cytoplasm and breaks down one molecule of glucose into two molecules of pyruvate, generating 2 ATP and 2 NADH.

Pyruvate Oxidation: Each pyruvate is transported into the mitochondria and converted into acetyl-CoA, releasing 1 CO2 and producing 1 NADH per pyruvate. Since there are two pyruvates, this results in 2 CO2 and 2 NADH.

Krebs Cycle: Each acetyl-CoA enters the Krebs cycle, which occurs in the mitochondrial matrix. For each acetyl-CoA, 2 CO2, 3 NADH, 1 FADH2, and 1 ATP are produced. Since there are two acetyl-CoA molecules, this results in 4 CO2, 6 NADH, 2 FADH2, and 2 ATP.

Combine the totals: Add the products from all stages. Glycolysis contributes 2 ATP and 2 NADH, pyruvate oxidation contributes 2 CO2 and 2 NADH, and the Krebs cycle contributes 4 CO2, 6 NADH, 2 FADH2, and 2 ATP. This results in a total of 6 CO2, 10 NADH, 2 FADH2, and 4 ATP.
