A myelinated neurone is insulated by a layer of Schwann cells that make up the myelin sheath. This aids in the faster conduction of an action potential down the neuronal axon. Depolarisation of the axon c...

unevenly thickened cell wall able to change shape / bendtransport proteins / ion pumps, in plasma membrane(presence of) chloroplasts (to provide, ATP / energy)

Firstly, depolarization of the neuronal membrane occurs. This is due to a stimulus which causes voltage-gated sodium ion channels to open, allowing sodium ions to diffuse down their concentration gradient...

The Endocrine part of the Pancreas is the Islets of Langerhans which contain alpha and beta cells. These cells secrete hormones directly into the blood. The alpha cells secrete glucagon and the beta cells...

Embryonic growth requires cell division and the subsequent synthesis of new tissue. This invariably requires energy and raw materials to progress. Phosphate is an important component of ATP, which acts as...
