identify the subcellular structure of the neuron that forms the basis for the transmission of nerve impulses. (2 points) describ
melisa1 [442]

The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.

What are the steps in impulse transmission between neurons?

  • The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
  • Voltage gated Calcium channels open .
  • Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
  • Calcium influx triggers release of neurotransmitter.
  • This neurotransmitters bind to postsynaptic membrane and new impulses are created.

Synaptic vesicle under resting condition:

  1. The neurotransmitter molecules are stored in synaptic vesicles.
  2. If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
  3. During resting condition, they are placed randomly.
  4. When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.

Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.

ikadub [295]

Answer:

Statement A - cellular membrane

Statement B - eukaryote

Statement C - spore

Statement D - prokaryote

Explanation:

The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.

Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.

Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.

An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.

What contribution to energy do carbohydrates make?
professor190 [17]

Answer:

Most of the carbohydrates in the meals you consume are digested and crushed down inside glucose before accessing the bloodstream. Glucose in the blood is used up within your body's cells and applied to provide a fuel molecule called adenosine triphosphate (ATP) through a sequence of complex processes known as cellular respiration.
