In a hypothetical experiment, a scientist genetically modifies a C4 plant to lack PEP carboxylase. Which of the following would be the MOST likely outcome under normal atmospheric conditions?
The plant would switch to CAM photosynthesis.
The plant would exhibit significantly reduced CO2 fixation and increased photorespiration.
CO2 fixation would remain unchanged, but the plant would require more water.
The plant would grow more efficiently due to reduced energy expenditure in the C4 pathway.

Under conditions of high temperature and light intensity, why do C4 plants show higher photosynthetic rates compared to C3 plants?
C4 plants have a higher affinity for CO2 than C3 plants.
C4 plants open their stomata more frequently than C3 plants.
C4 plants can utilize a wider range of light wavelengths compared to C3 plants.
