Dopamine acts as a messenger between brain cells and chemical messengers in the brain are called neurotransmitters(神经递质). They relay(转送) signals from one cell to its neighbor. Different neurotransmitters are made in different parts of the brain. Two main brain areas produce d...
For example, her team pinpointed an enzyme that, when mutated, can enhance the placebo effect. Called catechol-O-methyltransferase (COMT), it helps to remove the chemical messenger dopamine from the gaps between neurons. Some people possess a form of COMT that doesn't efficiently clear away ...
What is the chemical structure of an amino acid? What type of replication of genes is used during conjugation? If a protein has 1398 nucleotides how many amino acids will be made? A gene is best defined as: A. A segment of DNA that codes for a functional product. B. Three nucleo...
Dopamine is a hormone and a type ofneurotransmitter, or chemical messenger, made in your brain. Your nervous system uses it to send messages between nerve cells. These messages also travel between your brain and the rest of your body.
Hormones are chemical messengers secreted by endocrine glands directly into the bloodstream. Discover their functions types, glands and disorders only at BYJU'S.
Neurons are the brain’s messenger cells. They are all interconnected through synapses, which are junction points that link them together in an expansive network through which electronic impulses and chemical signals are transmitted. They interact with one another through “spikes”, which are short,...
DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds from Chapter 9/ Lesson 1 255K Nucleic acids are large biomolecules used to store, transfer and convey genetic information in cells. Explore the structure of nucleotides and what polynucleotide and phosphodiester bonds do....
