What else can I help you with?
What is the enzyme that inactivates cAMP?
cAMP is inactivated by the enzyme phosphodiesterase (PDE), which breaks down cAMP into its inactive form, AMP. This process regulates the signaling pathway controlled by cAMP in cells.
What helps break down carbohydrates in the body?
Enzymes help break down carbohydrates in the body.
Substance used to break food down?
Enzymes are substances that break down food into smaller molecules to aid in digestion. They work by catalyzing chemical reactions that help to break down proteins, carbohydrates, and fats into simpler forms that can be absorbed by the body.
What do lipids break down into during the process of digestion?
During digestion, lipids break down into fatty acids and glycerol.
Can amylase break down cellulose?
No, amylase cannot break down cellulose. Amylase is an enzyme that specifically breaks down starches, while cellulose is a complex carbohydrate found in plant cell walls that requires different enzymes, such as cellulase, to break it down.
What is the enzyme that inactivates cAMP?
cAMP is inactivated by the enzyme phosphodiesterase (PDE), which breaks down cAMP into its inactive form, AMP. This process regulates the signaling pathway controlled by cAMP in cells.
Which intracellular substance degrades cAMP thus inactivating the response to a hormone?
Phosphodiesterase degrades cAMP in the cell, leading to the inactivation of the response to a hormone. This enzyme is crucial in regulating signal transduction pathways by breaking down cAMP into AMP.
What intracellular substance degrades cAMP and inactivating the response to a hormone?
Phosphodiesterase is the intracellular substance that degrades cAMP, leading to the inactivation of the cellular response to a hormone. This enzyme breaks down cAMP into AMP (adenosine monophosphate), thereby terminating the signal transduction pathway initiated by the hormone.
What is the medical definition of phosphodiesterase?
Phosphodiesterase in medical terms means a class of enzymes that are found in nucleic acids. They break down and produce even smaller nucleotide units.
What terminates cell signaling by inactivating cAMP?
Phosphodiesterase
What is the function of Phosphodiesterase?
Phosphodiesterase breaks down cAMP. While at first glance this may appear to be a problem, it is quite the opposite. Because of the amplification effect, most hormones need to be present only briefly to cause the desired results.

What is the mechanism of action of methylxanthine as a bronchodilator?
Methylxanthines like theophylline work as bronchodilators by inhibiting phosphodiesterase enzymes, particularly phosphodiesterase-4. By blocking these enzymes, methylxanthines prevent the breakdown of cyclic AMP which leads to smooth muscle relaxation in the airways, resulting in bronchodilation and improved airflow.
What hormone lowers c AMP concentration in liver cells is?
The hormone that lowers cyclic AMP (cAMP) concentration in liver cells is insulin. Insulin activates phosphodiesterase, an enzyme that breaks down cAMP, leading to a decrease in its levels. This action counteracts the effects of glucagon and catecholamines, which typically raise cAMP levels and promote glucose release from the liver. As a result, insulin plays a crucial role in regulating glucose homeostasis.
What effect would an inhibitor of phosphodiesterase activity would have?
An inhibitor of phosphodiesterase activity would increase the levels of cyclic AMP and/or cyclic GMP in the cell. This may lead to prolonged signaling cascades, affecting various physiological processes such as smooth muscle relaxation, platelet aggregation, and neurotransmitter release.
What does the idiom break camp mean?
It's not an idiom. To break camp means to break it up, to pack your things and leave the area. It can be used as slang, however, to mean a group "packing up" and leaving.
