Question

Choose the correct answers from the alternatives given :
In a eukaryotic cell, most of the enzymes of the Krebs cycle are located in the

• A. intermembrane space
• B. mitochondrial matrix
• C. inner mitochondrial membrane
• D. plasma membrane

Answer 1

The correct option is B mitochondrial matrix

• Kerb cycle is a part of aerobic respiration.
• After the reaction of glyolysis that takes place in cytoplasm which ends in formation of pyruvic acid.
• The pyruvic acid is converted to Acetyl CoA which will enter the kerb cycle for further reactions.
• For the further reaction in eukaryotic cells the acetyl coA will enter the mitochondria
  
• This kerb cycle takes place in mitochondria and so that all the enzymes that are required for the cycle are present in the mitochondrial matrix.
• Therefore the correct answer is option 'mitochondrial matrix'.
