If you did that what would happen is you would see antibody levels rise even more sharply than before.

As cyclic AMP levels rise inside the cell, something about cell behavior changes.

细胞内cAMP水平升高,细胞行为就会发生一些改变

That rate of rise is steeper so they--antibody levels go up more rapidly and they reach a higher level.

同时,上升速度也更加迅速,以达到更高的浓度水平

If you have two different ligands stimulating two different receptors, and one causes activation of this enzyme and generation of cyclic AMP, cyclic AMP levels will start to rise.

如果有两种不同的配体,刺激不同的受体,一种能够活化酶,并促进生成cAMP,cAMP的水平就会升高
