Answer:C
Explanation:
It is important for the cell not to activate glycolysis and gluconeogenesis at high rate simultaneously because it is expensive for the cell. 
In the break down of one molecule of glucose to pyruvate, one ATP is used in the conversion of glucose to glucose-6-phosphate and one ATP is used in the conversion of fructose-1-phoshate to fructose-1,6-biphosohate. While a total of four ATPs are produced. 
Making it a net gain of 2 ATP in glycolysis.
Gluconeogenesis  produces no ATP and requires equivalents of 6 ATP (4 ATP and 2GTP) for one molecule of glucose produced.
(Glycolysis +2ATP) + (gluconeogenesis -6ATP) = -4ATP
There's a net loss of 4ATP if both reactions are activated simultaneously.
 
        
             
        
        
        
Answer:
 Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent.
