Question

Which of the following statements is not correct about cellular respiration (a)Energy is released,(b)Occurs in all living forms,(c)Oxygen is used and CO2 is liberated and (d)Haemoglobin is always needed in all forms

​

Answer 1

Answer:

(c) Oxygen is used and $CO_2$ is liberated is not correct about cellular respiration.

Explanation:

• All living creatures' cells, both autotrophs and heterotrophs, engage in cellular respiration.
• Respiration is an exothermic process that releases energy. Adenosine triphosphate (ATP) molecules store the energy. Other mechanisms in cells can break down ATP, releasing the stored energy.
• Using $O_2$ to break down glucose and oxidise it to $CO_2$ and $H_2O$, cellular respiration creates energy for daily life functions.
• For cellular respiration, haemoglobin transports oxygen to all living cells.

Answer 2

Answer:

c) Oxygen is used and CO2 is liberated.
