Francesco redi performed an experiment in 1668. in the experiment, he placed rotting meat in two jars. the first jar was left open. after a few days, fly larvae were found on the decaying meat inside. the mouth of the second jar was covered with gauze. after a few days, the decaying meat inside was free of fly larvae, but larvae were found on the gauze. this experiment supports the hypothesis that

The experiment performed by Francesco Redi supports the hypothesis that fly larvae only come from adult flies based on his experiment design using a covered-meat and non-covered meat. In addition, he also believed that maggots came from the fly rather than from the rotten meat by using the same experiment design.

Explanation:

Epinephrine (i.e., adrenaline) is a hormone secreted by the adrenal glands and some neurons. This hormone binds to a type of G protein-coupled receptor called beta-adrenergic receptors. This binding results in the activation of adenylate cyclase and the intracellular production of a second messenger known as cyclic adenosine monophosphate (cAMP), which is synthesized from adenosine triphosphate (ATP). cAMP activates different kinases that phosphorylate specific protein substrates, thereby activating and inhibiting different enzymatic reactions. Finally, this process activates an enzyme called glycogen phosphorylase that breaks down glycogen into glucose which is released in the blood.
