Question

question 16
which of the following best describes aerobic respiration?
processes that do not require oxygen and produce atp
processes that require oxygen and produce atp
processes that require atp
processes that produce atp

Explanation:

Aerobic respiration is a metabolic process. The key characteristic of aerobic respiration is that it requires oxygen ($O_2$) as the final electron acceptor in the electron - transport chain. During aerobic respiration, glucose ($C_6H_{12}O_6$) is broken down in the presence of oxygen. The overall chemical equation for aerobic respiration is $C_6H_{12}O_6+6O_2
ightarrow6CO_2 + 6H_2O+\text{Energy (ATP)}$. So, it is a process that requires oxygen and produces ATP.

• The first option “processes that do not require oxygen and produce ATP” describes anaerobic respiration (such as fermentation).
• The third option “processes that require ATP” is incorrect because aerobic respiration produces ATP, not just requires it.
• The fourth option “processes that produce ATP” is too general as both aerobic and anaerobic processes can produce ATP.

Answer:

processes that require oxygen and produce ATP
