Question
Which of the following intermediates is directly involved in both glycolysis and the Krebs cycle?
Question 2
Answer
- a. Citrate
- b. Pyruvate
- c. Acetyl-CoA
- d. Oxaloacetate
Solution
The intermediate that is directly involved in both glycolysis and the Krebs cycle is Pyruvate.
Here's why:
In the process of glycolysis, glucose is broken down and converted into two molecules of Pyruvate. This process occurs in the cytoplasm of the cell.
The Pyruvate produced in glycolysis is then transported into the mitochondria, where it is converted into Acetyl CoA, which is the first step in the Krebs cycle (also known as the citric acid cycle or TCA cycle).
So, Pyruvate is the intermediate that is directly involved in both glycolysis and the Krebs cycle.
