Glycogen synthesis was monitored in a liver cell in the presence of glucagon binding to the
$\beta$2-adrenergic receptor and after its removal. How would the activity of enzymes involved in glycogen synthesis and glycogen degradation be altered if the experiment were carried out after the cells were treated with caffeine, an inhibitor of cAMP phosphodiesterase? Explain your reasoning.
