Question

2. Which gas present in the air is essential for aerobic respiration? What is the role of oxygen during respiration?

Answer 1

$\bf\huge{\underline{\purple{ANSWER}}}$

Oxygen present in air is responsible for respiration. The oxygen breaks down food and releases energy. oxygen is critical for aerobic respiration.

aerobic respiration can not take place without oxygen because oxygen is the gas used for the breakdown of food to release energy. Oxygen is the gas present in the air which is essential for aerobic respiration.

Answer 2

Answer:

Oxygen is present in aerobic respiration.

Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Energy is released in the reaction.

Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
