Answer:

TRUE

Explanation:

In the cardiovascular system, the blood flows from <u>high pressure to low pressure.</u>

In the ventricular ejection phase, when the muscles of the ventricles contract, the<u> pressure gradient in ventricles rises</u>.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary?.
mr_godi [17]

Cells respond to environmental effects through signal transduction, which promotes healthy cell growth and normal cell function.

<h3>Why is the signal transduction step necessary?</h3>

The reason why after a signal binds to a signal receptor, we need the next step is as follows:

  • For the purpose of triggering an appropriate cellular response, living creatures have evolved a vast range of intricate procedures to send signals from the outside to the inside.
  • These molecular pathways can develop flaws that result in a variety of ailments, including diabetes, cancer, and psychotic conditions.
  • It is the mechanism by which a cell responds to the stimuli it receives from the environment by diffusion of those signals to its internal compartments.
  • Signal transduction is the process by which a cell translates a given signal or external stimulus into another signal or specific response.
  • First, a particular receptor on the cell's membrane or cytoplasm must be activated by a signaling molecule (also known as a ligand). transduction.
  • Ligand-receptor binding is extremely specific; it can be compared to a lock and key.
  • Second messengers are chemicals that enable intracellular signal amplification after a signal has been received.
  • A ligand's interaction to a receptor may result in the production of hundreds of second messenger molecules, which may then change thousands of effector molecules to cause a variety of reactions.
  • Signal transduction enables cells to perceive, interpret, and react to various environmental signals, enabling them to carry out their usual functions.
