3. What are the differences between aerobic and anaerobic respiration? Name some
organisms that use the anaerobic mode of respiration.
2. How are the alveoli designed to maximise the exchange of gases?
Answers
Aerobic respiration takes place in presence of oxygen, where glucose a six carbon molecule is broken down into pyruvate, a three carbon molecule
Eg: Humans, dogs etc.
In anaerobic respiration, glucose is broken down into pyruvate in the absence of oxygen.
Eg: some bacteria, blue green algae etc.
Alveoli are small bubble like terminals present in large numbers inside the lungs. These are placee in a compact area. If we are to open it and spread it out, it would take up a lot of space....thus it increases the efficiency of the process of exchange of gases in our lungs
Answer:
Cellular respiration is a process that takes place inside the cells, where the breakdown of glucose molecules releases energy. The process can be conveniently divided into two categories based on oxygen usage, namely aerobic and anaerobic respiration.
Differences between aerobic and anaerobic respiration
The difference between aerobic and anaerobic respiration is tabulated below.
Aerobic Respiration Anaerobic Respiration
It is the process of cellular respiration that takes place in the presence of oxygen gas. It is the process of cellular respiration that takes place in the absence of oxygen gas.
It involves the exchange of gases between the organism and the outside environment. Exchange of gases is absent.
It can be found in the cytoplasm and the mitochondria It can be found only in the cytoplasm.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide, and energy
All higher organisms such as mammals have this type of respiration. Lower organisms such as bacteria and yeast use this type.
