Question

Match with the appropriate subcellular location. -7. lower pH associated with electron transport -8. pyruvate to acetyl-CoA a. cytoplasm b. space between c. outer mito membrane d. inner mito membrane e. cell membrane f. mitochondrial matrix 9. TCA cycle enzymes mito membranes -10. ATP formed 11. hexokinase, glucokinase -12. cytochromes in ets 13. aldolase -14. ATP synthase attached to 15. malate dehydrogenase

Answer 1

7) Lowered pH associated with electron transport- space between mito membranes

   With proteins pumped from mitochondrial matrix to inner membrane the pH is lowered with more protons

8) Pyruvate to acetyl CoA- Mitochondrial matrix

In the mitochondrial matrix pyruvate is oxidatively decarboxylated by pyruvate dehydrogenase enzyme to form acetyl CoA

9) TCA cycle enzymes- mitochondrial matrix

All enzymes required for the process of TCA cycle occurs in mitochondrial matrix.

10) ATP formed in- mitochondrial matrix

   ATP is generated by Kerbs cycle in the mitochondrial matrix from pyruvate.

11) Hexokinase,glucokinase- Cytoplasm

These enzymes are involved in the glycolysis present in the cytoplasm

12) Cytochrome ETS- Inner membrane of mitochondria

Cytochrome is responsible of electron transport found in inner mitochondrial membrane

13) Aldolase- Cytoplasm

Aldolase enzyme helps in the conversion fructose 1,6 bisphoshphate to glyceraldehyde 3 phosphate and all these reactions occurs in cytoplasm.

14) ATP synthase attached to- Inner mito membrane

    ATP synthase is located in the inner mitochondrial membrane

15) Malate dehydrogenase- Cytoplasm

Malate dehydrogenase reduces oxaloacetate to malate this enzyme occurs in the cytoplasm.
