Answer: A) 2ATP
Explanation:
The stage of cellular respiration shown in the image is the glycolysis. It is the first step of the cellular respiration that occurs in the cytoplasm of the cell. It is a sequence of reactions catalysed by various enzymes. During glycolysis 6-carbon glucose is converted into two 3-carbon pyruvic acids. Glycolysis begins with activation of glucose. It is activated by using 2ATP and at the end of glycolysis 4ATPs are formed. Thus, net gain of ATP is 4 -2 = 2ATP.
