Answer:
It takes energy to break bonds. Energy is released when bonds are formed. If a reaction is endothermic, it takes more energy to break the bonds of the reactants than is released when the bonds of the products are formed
I cannot find the propositions if it is a MCQ, so I will tell what a bacterial mutualism is:
Mutualism is an exchange between species (two or more) in which the mixed organisms profit from this exchange. Unlike commensalism, the associated species adapt, because the modification of one can affect the survival and reproduction of the affiliated species.
Many mutualistic bacteria live and develop in us, for example, the intestinal flora synthesizes vitamin K, a vitamin that is necessary for the absorption of our food. This same intestinal flora also hinders the proliferation of pathogenic bacteria as well as that of commensal bacteria potentially dangerous.
The answer is the number 2. Why? Because the cytoplasm is a fluid that sustains the cell shape. The mitochondria is a organelle, ribosomes are protiens and vacuoles are carriers/storage bins.
