if one molecule of glucose undergoes the reaction of glycolysis, what is produced? ( 1 point )
A.) ATP, 3 NADH, and 1 Pryuvate
B.) 4 ATP, 6 NADH, and 2 FADH2
C.) 2 ATP, 2 NADH, and 2 Pryuvate
D.) 3 NADH, and 1 FADH2
The correct answer is C.) 2 ATP, 2 NADH, and 2 Pyruvate.
The correct answer is:
C.) 2 ATP, 2 NADH, and 2 Pyruvate
During the process of glycolysis, one molecule of glucose is converted into two molecules of pyruvate. Along with the pyruvate, two molecules of ATP and two molecules of NADH are produced. Option C is the correct answer as it represents the correct products of glycolysis.
To determine the answer, we need to understand the process of glycolysis, which is the breakdown of glucose. During glycolysis, one molecule of glucose is converted into two molecules of pyruvate. Along with the production of pyruvate, certain energy-rich molecules are also generated.
Here's a step-by-step breakdown of the glycolysis process:
1. Glucose is initially phosphorylated and converted into glucose-6-phosphate.
2. Glucose-6-phosphate is then converted into fructose-6-phosphate.
3. Fructose-6-phosphate is further phosphorylated and converted into fructose-1,6-bisphosphate.
4. Fructose-1,6-bisphosphate is split into two molecules of glyceraldehyde-3-phosphate.
5. The two molecules of glyceraldehyde-3-phosphate are converted into two molecules of pyruvate.
6. During this process, energy-rich molecules such as ATP and NADH are produced.
Now, let's analyze the options provided:
A.) ATP, 3 NADH, and 1 pyruvate: This option states that one molecule of glucose undergoing glycolysis produces ATP, 3 NADH, and 1 pyruvate. This is incorrect since glycolysis produces two molecules of pyruvate, not one.
B.) 4 ATP, 6 NADH, and 2 FADH2: This option is incorrect because glycolysis itself only produces a small amount of ATP (2 ATP molecules per glucose molecule), along with NADH. It does not produce FADH2.
C.) 2 ATP, 2 NADH, and 2 pyruvate: This option is correct. Glycolysis, the breakdown of glucose, produces 2 molecules of ATP, 2 molecules of NADH, and 2 molecules of pyruvate.
D.) 3 NADH and 1 FADH2: This option is incorrect because glycolysis does not produce FADH2.
Hence, the correct answer is C.) 2 ATP, 2 NADH, and 2 pyruvate.
