Where does the citric acid cycle occur in eukaryotes?

a. in the cytosol of cells

b. in the intermembrane space of mitochondria

c. in the inner membrane of mitochondria

d. in the matrix of mitochondria

Expert Solution & Answer

Summary Introduction

Introduction:

The citric acid cycle (CAC) or tricarboxylic acid cycle (TCA cycle) is a series of biochemical reactions, a stage of cellular respiration in cells that breakdowns the organic fuel molecules such as carbohydrates, proteins, and fats and releases energy through the oxidation of acetyl-CoA.

Answer to Problem 2TYK

Correct answer:

In the matrix of mitochondria

Explanation of Solution

Explanation/Justification for the correct answer:

Option (d) is given as mitochondrial matrix. Adenosine triphosphate (ATP) is classified as the source of energy in each cell in all the organisms. The conversion of glucose through a number of steps drives this energy conversion to ATP. One of the stages or a cycle is CAC. The space enclosed within the inner membrane of the mitochondria is called the matrix. The enzymes responsible for conducting the CAC are located in the matrix of the mitochondria. Hence, the Option (d) is correct.

Explanation for incorrect answers:

Option (a) is given as cell cytosol. The first stage of the breakdown of glucose is the glycolysis, where the end product is a 3-carbon compound called pyruvate. This reaction takes place in the cytosol in the eukaryotes. The space between the outer as well as the inner mitochondrial membranes and cristae make up the intermediate space, which contains no enzymes for these reactions. Hence, the option (a) is incorrect.

Option (b) is given as mitochondrial intermembrane space. The inner membrane of the mitochondria contains transporter proteins, which transfer the pyruvate to the mitochondrial matrix for further processing. Hence, the option (b) is incorrect.

Option (c) is given as mitochondrial inner membrane. Except glycolysis, all the enzymes for cellular respiration occur mostly in the mitochondrial matrix in the eukaryotes. Hence, the option (c) is incorrect.

Conclusion

The citric acid cycle (CAC) occurs in the matrix of mitochondria in eukaryotes.
