B Correct answer
Explanation

Kreb's cycle takes place in matrix of mitochondria. Hence, all enzymes for Kreb's cycle is found in mitochondria.

Multiple choice
  1. Plasma membrane - covers and protect the cell contents

  2. Cytoplasm - all cell organelles are suspended in it

  3. Endoplasmic reticulum - helps in intracellular transport

  4. Golgi bodies - stores, condenses and packs material

  5. Lysosomes - sites of cellular respiration

Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is an incorrect pair as lysosomes are not the site of cellular respiration.
