MCQ
$TCA$ cycle enzymes are present in
- ACytoplasm
- BInter membrane space of mitochondria
- ✓Mitochondrial matrix
- DInner membrane of mitochondria
✓
Answer
Correct option: C.
Mitochondrial matrix
c
In eukaryotes, all the reactions of tricarboxylic acid $(TCA)$ cycle or Krebs' cycle takes place in the matrix of mitochondria because all enzymes of this cycle are found in the matrix of mitochondria except Succinic dehydrogenase, which is located in the inner membrane of mitochondria. In prokaryotes, Krebs' cycle occurs in cytoplasm
