Aerobic Respiration:
(1) More common in higher organisms
(2) Leads to complete oxidation of Organic substance in the presence of oxygen and release of Carbon-dioxide
(3) Large amount of energy present in substrate and amount of water is also released out
(4) All of these
The events of Aerobic Respiration include:
p. | The complete oxidation of Pyruvate by the stepwise removal of all the hydrogen atoms leaving two molecules of Carbon-dioxide |
q. | The passing on of the electrones removed as part of the Hydrogen atoms to molecular oxygen with simultaneous synthesis of ATP |
r. | Pyruvate is transported from Cytoplasm to Matrix |
s. | Two events of Aerobic Respiration takes place within mitochondria. |
t. | The first process takes place in the matrix of mitochondria while second process is located on the inner membrane of mitochondria |
The correct ones are
1. | pqrst | 2. | qrst |
3. | pqrs | 4. | prs |
