Another general principle of physiology states that physiological processes require the transfer and balance of matter and energy. How is energy balance-related to intracellular signaling?
The general principle of physiology that structure is a determinant of—and has coevolved with—function can be considered at the molecular, cellular, and organ levels. How is this principle illustrated by the binding of messengers to their receptors?
Nitric oxide produced by the endothelial layer of blood vessels stimulates the smooth muscle layer underneath to relax, leading to widening of blood vessel lumen and subsequent decrease in blood pressure. This type of cellular communication between endothelial and smooth muscle cells is an example of what type of chemical signaling?

- What is the role of phosphorylation in the transmission of intracellular signals?arrow_forwardThe hormones known as "catecholamines" (adrenaline, noradrenaline, and dopamine) are not lipid-soluble. Therefore their receptor sites are: O a) On the inside of the plasma membrane O b) On the outside of the plasma membrane O c) In the cell cytoplasm O d) In the cell nucleusarrow_forwardSignaling by soluble extracellular molecules can be classified as endocrine, paracrine, or autocrine. Describe how these three types of cellular signaling differ. Growth hormone is secreted from the pituitary, which is located at the base of the brain and acts through growth hormone receptors located on the liver. Is this an example of endocrine, paracrine, or autocrine signaling? Why?arrow_forward
- Compare and contrast signaling events in the nervous vs. endocrine systems. How does a “message” get from the original neuron or endocrine gland to the target? How does the signal get transduced into something the target cell can respond to? Be sure to include a description of the signaling molecules and cellular receptors involved in each of these systems.arrow_forwardIn muscle cells, when adrenaline binds to beta-adrenergic receptor, it trigger signaling cascade leading to active glycogen phosphorylate breaks up glycogen into glucose subunits (Glycogen -> G1P).
