False Statement: Photorespiration results in maximum production of ATP.
Explanation:
Photorespiration is a process that occurs in plants when the level of carbon dioxide (CO2) in the air is low. This process competes with photosynthesis and results in a loss of energy and carbon from the plant. Here are some important points to understand about photorespiration:
- During photorespiration, a molecule of oxygen (O2) is added to ribulose bisphosphate (RuBP) instead of carbon dioxide (CO2). This reaction is catalyzed by the enzyme Rubisco, which normally adds CO2 to RuBP during photosynthesis.
- The resulting molecule is broken down into two smaller molecules, one of which is phosphoglycolate. This molecule cannot be used directly by the plant and must be converted into a usable form through a series of reactions called the photorespiratory pathway.
- The photorespiratory pathway requires energy in the form of ATP and reducing power in the form of NADPH. These molecules are produced during photosynthesis and are used to power the conversion of phosphoglycolate into a usable form.
- Thus, photorespiration results in a net loss of energy and carbon for the plant, as it consumes ATP and NADPH without producing any usable organic compounds.
- In contrast, photosynthesis results in the production of organic compounds such as glucose and the release of oxygen as a byproduct. This process requires energy in the form of light and produces ATP and NADPH as byproducts.
Therefore, the false statement is that photorespiration results in maximum production of ATP. In fact, photorespiration consumes ATP without producing any additional energy, while photosynthesis produces ATP as a byproduct.

In photorespiration, neither ATP nor NADH will be produced instead CO2 is released and ATPs are utilised. That's y it's called as a wasteful process. So op C.
