Answer 1

A C4 plant is a plant that cycles carbon dioxide into four-carbon sugar compounds to enter into the Calvin cycle. This reaction requires inorganic phosphate and ATP plus pyruvate, producing phosphoenolpyruvate, AMP, and inorganic pyrophosphate (PPi). The next step is the fixation of CO2 into oxaloacetate by the enzyme PEP carboxylase. Both of these steps occur in the mesophyll cells: pyruvate + Pi + ATP → PEP + AMP + PP.A C4 plant is a plant that cycles carbon dioxide into four-carbon sugar compounds to enter into the Calvin cycle. These plants are very efficient in hot, dry climates and make a lot of energy. Many foods we eat are C4 plants, like corn, pineapple, and sugar cane.

Answer 2

A C4 plant sounds like something that should be associated with Hollywood action movies! However, it is just a type of plant that uses a specific photosynthesis mechanism (C4 photosynthesis) in order to avoid photorespiration. Photorespiration is a wasteful reaction that occurs when plants take in oxygen and give out carbon dioxide instead of taking in carbon dioxide and releasing oxygen.

All plants make energy during the Calvin cycle(the process where plants take up CO2 and turn it into sugar energy); however, in hot, sunny, dry climates, C4 plants are much more efficient than C3 plants (plants that perform C3 photosynthesis - the most common type).

The difference between C3 and C4 plants is that C4 plants make a four-carbon sugar during the Calvin cycle instead of two three-carbon sugars as in C3 plants. This larger sugar in C4 plants brings more CO2 to the RuBisCO enzyme, reducing oxygen levels and making the process energy-intensive. More CO2 is brought into the process because of how cells are located.

C4 plants like very sunny areas with warm temperatures. They can withstand cool evening temperatures.
