Question

Select the incorrect statement from the following.

• A. During oxidation within a cell all the energy contained in respiratory substrate is released free into the cell.
• B. Energy is released in a series of slow step wise reactions controlled by enzymes.
• C. Energy is trapped as chemical energy in the form of ATP.
• D. Energy released by oxidation, in respiration is not used directly.

Answer 1

Answer: (A)

During oxidation within a cell, all the energy contained in the respiratory substrate is not released free into the cell. Some of it is trapped in the form of high energy phosphate bonds to form ATP and a large amount of it is lost in the form of heat.
