Detailed explanation-1: -The first product of CO2 fixation is a C4 organic acid, oxaloacetate, formed by the carboxylation of phosphoenolpyruvate (PEP) by PEP carboxylase. The oxaloacetate is converted to other C4 acids (malate or aspartate) and transferred to the bundle sheath.

Detailed explanation-2: -Final Answer: The first stable product in CAM/C4 plants is oxaloacetic acid.

Detailed explanation-3: -4 Carbon (4C) compound-Oxaloacectic acid (OAA) is the first stable compound produced in C4 cycle.

Detailed explanation-4: -The product of this reaction is the four-carbon acid oxaloacetate, which is reduced to malate, another four-carbon acid, in one form of the C4 pathway. Malate then is transported to bundle-sheath cells, which are located near the vascular system of the leaf.

Detailed explanation-5: -Explanation: The first stable compound produced in the Calvin cycle is a 3 carbon compound, which is 3 phosphoglyceric acid (PGA). Due to this, the Calvin cycle is also called as C3 cycle. In C4 plant, the first stable product is a 4 carbon compound, which is Oxaloacetic Acid (OAA).
