Answer:
In chemical transmission the release of chemical messengers known as neurotransmitters occurs. Neurotransmitters carry information from the presynaptic or transmitter neuron to the postsynaptic or recipient cell.
As you may recall from the article on the structure and function of the neuron, synapses are usually formed between the nerve terminals - axon terminals - of the sending neuron and the cell body or dendrites of the receiving neuron.
Scheme of synaptic transmission. An action potential travels through the axon of the presynaptic or emitting cell, and reaches multiple axon terminals branching from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic or recipient cell. This place of close connection between axon and dendrite is the synapse.
A single axon can have multiple ramifications, which allows it to synapse with several postsynaptic cells. Similarly, a single neuron can receive miles of synaptic inputs from many different presynaptic or emitting neurons.
Within the axon terminal of a transmitter cell there are many synaptic vesicles. These are membranous spheres full of neurotransmitter molecules. There is a small space between the axon terminal of the presynaptic neuron and the postsynaptic cell membrane, this space is called synaptic space.
Answer:
Diabetes is a condition in which your blood glucose, often known as blood sugar, is abnormally high. Your main source of energy is blood glucose, which comes from the food you eat. Insulin, a hormone produced by the pancreas, aids glucose absorption into cells for use as energy.
Hope this helps!
Answer:
Producers ( also called autotrophs) are the organisms that synthesize their own ( glucose) food using carbon dioxide and water in the presence of sunlight ( photosynthesis). They use energy from sunlight to convert it into chemical energy ( that is stored in the glucose). Autotrophs occupy the base of a food chain within the ecosystem as they are first trophic level for the energy transfer.
Decomposers ( such as bacteria and fungi that act on dead plants and animals) can recycle the organic matter back into the food web and biogeochemical cycles in the form of nutrients such as carbon and nitrogen.
Thus, the correct answers are-
1) Producers
2) Decomposer
3) Sunlight
4) Base
