    The \[{{C}_{4}}\] plants differ from \[{{C}_{3}}\] plants with reference to the

    A) substrate that accepts\[C{{O}_{2}}\]in carbon assimilation

    B) type of end product

    C) type of pigment involved in photosynthesis

    D) number of ATP that are consumed in preparing sugar

    Correct Answer: A

    Solution :

                    Plants that utilise primarily \[\text{RuBP}\]to fix \[C{{O}_{2}}\], which results in the formation of a 3 carbon compound (3 PGA) are called \[{{C}_{3}}\] plants. Hatch and Slack proposed a new pathway in plants for \[C{{O}_{2}}\] fixation via the carboxylation of PEP (phosphoenol pyruvate). Because the products are 4 carbon compound, the plants are known as \[{{C}_{4}}\] plants.
