At midnight, what is happening in the leaf of a plant?

• Respiration

• Photosynthesis

• Respiration and Calvin cycle

• None of the reaction above

Which type of plant fixes carbon only at night?

• C3

• C4

• CAM

• none of the plant

Why are C4 plants able to undergo photosynthesis without photorespiration?

• They do not take part in the Calvin cycle.

• They are adapted to cold and wet climate.

• They are able to conserve water efficiently.

• They use PEP carboxylase to initially fix CO2.

The enzyme responsible for Carbon Fixation in C3 Photosynthesis is

• RUBISCO

• PEP Carboxylase

• Hexokinase

• Pyruvate DeHydrogenase
