Aerobic respiration is composed of two crucial events. Choose the correct option regarding the site of these events.
Options
- ABoth of the events take place in the matrix of the mitochondria.
- BBoth of the events take place in the inner membrane of the mitochondria.
- COne event takes place in the matrix of the mitochondria and the other in the inner membrane of the mitochondri
- DNeither of the events take place in the mitochondria.
Correct answer
C. One event takes place in the matrix of the mitochondria and the other in the inner membrane of the mitochondri
Step-by-step solution
For aerobic respiration to take place within the mitochondria, the final product of glycolysis, pyruvate is transported from the cytoplasm into the mitochondria. The crucial events in aerobic respiration are: • The complete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms, leaving three molecules of CO 2 . • The passing on of the electrons removed as part of the hydrogen atoms to molecular O 2 with simultaneous synthesis of ATP. The first process takes place in the matrix of the mitochondria
