The chief inhibitory neurotransmitter in the brain is ____, and the chief excitatory neurotransmitter is ____.

Answers

Answer 1

The chief inhibitory neurotransmitter in the brain is GABA and the chief excitatory neurotransmitter is Glutamate.

Gamma-aminobutyric acid (GABA) is an amino acid that serves as the central nervous system's main inhibitory neurotransmitter (CNS). By preventing nerve transmission, it works to lower neuronal excitability. When GABA attaches to the GABA receptor protein in your brain, it exerts a relaxing effect. Anxiety, worry, and fear can all be relieved with the use of this. The most prevalent excitatory neurotransmitter in the brain and central nervous system is glutamate. You require it to maintain optimal brain function. Glutamate has a significant impact on how learning and memory are shaped. Glutamate must be present at the proper concentrations, locations, and times.

The main distinction between glutamate and GABA is that L-glutamic acid decarboxylase produces GABA from glutamate.

Characteristics that are genetically transferred from parents to their offspring are said to be a product of.

Answers

Characteristics that are genetically transferred from parents to their offspring are said to be a product of heredity.

The transfer of traits from one generation to the next is known as heredity, also known as inheritance or biological inheritance. Whether through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic make-up of their parents. Variations between people can accumulate through genetics and lead to the natural selection-driven evolution of species. Genetics is the study of heredity in biology. It is well acknowledged that DNA, a molecule that conveys genetic information, is a significant carrier of heritable traits. DNA is a lengthy polymer that contains four types of interchangeable bases. The entire set of characteristics that can be observed in an organism's structure and behavior is referred to as its phenotype.

These traits are the outcome of the interplay between the genotype and the environment.

Within eukaryotic cells, which organelle is surrounded by a double membrane and carries the coding that determines protein synthesis?

Answers

Within eukaryotic cells, Nucleus is surrounded by a double membrane and carries the coding that determines protein synthesis.

Nucleus- In terms of genomics, a nucleus is the organelle inside a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective transit of certain molecules (such proteins and nucleic acids) from and to the nucleus.

Genomics- In order to understand the structure and function of these sequences and of the ensuing biological products, genomics is the study of all or a portion of an organism's genetic or epigenetic sequence information.

When a person is in a state of fear, the hormone epinephrine is released. This stimulates the activation of energy-generating catabolic pathways in order to provide the body with energy for a response to danger. How would that be helpful to a person who encounters a lion?.

Answers

The release of the hormone epinephrine will be helpful to a person who encounters a lion because it will lead to the supply of more energy to the muscles in the body and increased blood supply due to which the person can run away from the place of danger to a safe place.

The adrenal gland is a part of the endocrine system of the body.

It consists of two parts- the adrenal cortex and adrenal medulla.

The adrenal medulla secretes two hormones- adrenaline/epinephrine and noradrenaline/norepinephrine.

These hormones are released in response to any stressful situation and during emergency conditions, so they are called emergency hormones or hormones of Fight or Flight.

These hormones have the following effects on the body:-

They increase alertness.

They increase the heartbeat, the strength of contraction of the heart, and also the respiratory rate.

They also stimulate the activation of energy-generating catabolic pathways.

The above-mentioned effects help a person to escape a stressful situation.

Thus, the release of the hormone epinephrine will be helpful to a person who encounters a lion because it will lead to the supply of more energy to the muscles in the body and increased blood supply  due to which the person can run away from the place of danger to a safe place.

During transcription, rna polymerase synthesizes ______ from a(n) ______ template.

Answers

During transcription, rna polymerase synthesizes RNA strand from a(n) DNA template.

What is transcription?

Transcription is a classic event in molecular biology in which the DNA is transcribed to mRNA.

Transcription is an important event mentioned in central dogma of molecular biology. It is from transcription, translation (synthesis) of proteins is possible.

Transcription occurs at specific site in the cell. In prokaryotes, transcription takes place in cytoplasm whereas in eukaryotes, nucleus is the site for transcription.

Transcription involves three main steps:

Initiation - Binding of an enzyme RNA polymerase at the promoter region initiates the process of transcription. Thus, an mRNA strand is produced from a DNA sequence.Elongation - Specific nucleotides are added to this mRNA strand through complementary base pairing (A-U, C-G).Termination - RNA polymerase comes across a termination sequence in a gene and stops the process.

After transcription, processing of mRNA is carried out so that it becomes mature and fully functional for translation process.

Therefore, transcription is important in copying information from DNA sequences for the correct synthesis of proteins.

How does the structure of the plasma membrane depend on the amphiphilic (means both hydrophobic and hydrophilic) nature of phospholipids?

Answers

The amphiphilic molecules arrange themselves into a bilayer, with their hydrophilic phosphate-containing heads facing the water on each side of the membrane and their hydrophobic tails directed towards the center, avoiding water.

A phospholipid is a lipid composed of two fatty acid tails, glycerol and a phosphate-linked head group. Biological membranes typically have two phospholipid layers with their tails pointing inward, a configuration known as a phospholipid bilayer.

The primary material of the plasma membrane is composed of phospholipids arranged in a bilayer. They are amphipathic, which means they have both hydrophobic and hydrophilic regions, making them ideal for this role.

Answers

Option D: The cells in the nervous system that handle information processing are called neurons.

Nerve cells, often called neurons, are the building blocks of the nervous system. They interact with the information and transfer this information along various distances through electrical impulses. The nervous system is generally made up of two types of cells: nerve cells and glial cells. Glial cells are the supporting system of neurons. The nervous system is broadly divided into two categories:

The central nervous system (CNS) contains the brain and spinal cord

The peripheral nervous system (PNS) contains neurons and their parts such as sensory neurons and motor neurons.

Analysis of the information brought in by sensory neurons is done in CNS while PNS works as transportation for these signals from one neuron to another. Motor neurons carry the signals out of the CNS after analysis.

Information processing in the nervous system is handled by neurons or their parts like interneurons that connect one neuron to another in the CNS.  These signals are then transferred by motor neurons to respond to stimuli.
