    DIRECTIONS: Carefully observe pictures given below and answer the following questions. A graph was plotted to show the energy output at two types of respiration. Identify the type of respiration denoted by curves A and B.

    A) Curve 'A' represents anaerobic respiration and curve 'B' represents aerobic respiration

    B) Curve   'A'   represents   aerobic respiration and curve 'B' represents anaerobic respiration.

    C) Both the curves represent aerobic respiration

    D) Both the curves represent anaerobic respiration

    Correct Answer: A

    Solution :

    Since energy output is less in curve 'A' than in curve 'B', so curve 'A' represents anaerobic respiration and curve 'B' represents aerobic respiration. Note: The energy released during aerobic respiration is approx. 20 times the energy released during anaerobic respiration.
