What takes place at the synapse?

2 answers:

7 0

The most commonly found synapses in humans are chemical synapses. This occurs due to electrical activity in the presynaptic neurons triggering the release of neurotransmitters.

The neurotransmitters disperse across the synaptic cleft to then bind themselves to specialized receptors of postsynaptic neurons. Once this occurs, the neurotransmitters then either excites or inhibits the postsynaptic neuron. Exciting the postsynaptic neuron leads to a firing of action potential (electrical impulses), whereas inhibiting the postsynaptic neuron prevents the transmission of a signal.

Answer:i think At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis.

The nurse is caring for a client with burns receiving opioid analgesics and who is sedated. which medications should the nurse a

nikitadnepr [17]

The most common side effect of opioid medication is Constipation because they reduce gastrointestinal motility, secretions, and blood flow. To treat constipation with non- pharmacological therapies, the patient should have a high-fiber diet, increased fluid intake, and increased physical activity. Due to the condition of the patient, it's not possible to get rid of the side effects with this type of therapy, so the nurse will have to prescribe stimulant laxatives to maintain regular bowel movements.

Explanation:

B. Lactic acid is produced from lactobacilli as the starter undergoes fermentation

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate (pyruvic acid) is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation. In lactic acid bacteria, the pyruvate produced is directly transferred to lactate (a form of lactic acid) producing NAD+.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Within cells, aerobic respiration may not occur due to several factors:

- a lack of inorganic, final electron acceptors
-incomplete or lack of a complete electron transport system
-missing genes for enzymes within the Kreb's cycle

How does a cloned sheep compare genetically to a sheep that is made using sexual reproduction

nikitadnepr [17]

Answer:

The cloned sheep is the result of nuclear fusion from two different sheeps. In one sheep the enucleated egg is fused with DNA of another sheep.

Explanation:

The cloned sheep is the result of nuclear fusion of 2 different sheep. In the cloning process, the egg cell of one sheep was enucleated. Then a DNA from another sheep had taken and put into the enucleated egg cell to fuse. Then the egg allowed to divide in the laboratory to the blastocyst stage. The blastocyst incorporated into a surrogate mother or a third sheep. The surrogate mother after some months gives birth to the cloned sheep.

The sheep produced by normal reproduction has the DNA of two parents. The sheep have two parents and resemble their parents.

In cloned sheep, there is no biological parent and have DNA of the donor sheep. That means the cloned sheep has a gene of a single sheep not the DNA of others. Because the egg cell was enucleated before the cloning process. The sheep are more like the donor DNA sheep not like the surrogate mother.

Marvin is suffering from the early stages of alzheimer's disease. which component of his working memory is most likely to be aff

olga nikolaevna [1]

Correct answer:
"All of these are equally affected."

When in Alzheimer's disease, all of the working memory is in peril. In early stages of Alzheimer's disease, all of these functions start to have problems. Phonological loop is basically the capacity to memorise speech or information in it. Central executive is the ability to switch attention from one activity to another that is needing more attention. The visuospatial sketch pad is the ability to handle visual and spatial information being able to judge distances for example. All of these are part o the working memory and are affected from the early stages of Alzheimer's disease.
