What happens to axoplasmic transportation if there is limited movement of the nerve?
xxTIMURxx [149]

During a limited movement of the nerve, axonal transport also <u>slows down</u>.

Axonal transport/axoplasmic transport/axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm.

Slow axonal transport is the movement of cytoskeletal polymers and cytosolic protein complexes along axons at average rates on the order of millimeters per day, which corresponds to nanometers per second.

Axon transport mechanisms play a major role in transporting nutrients, organelles and other molecules towards the presynaptic terminals.

catabolismo.

Explicación:

El tipo de acción metabólica que genera la glucólisis y la respiración celular se llama catabolismo porque en ambos procesos se descomponen las moléculas lo cual es una acción catabólica. El catabolismo es una forma de metabolismo que descompone moléculas más grandes en unidades más pequeñas que son utilizadas por la célula para liberar energía o utilizadas en otras reacciones anabólicas significa la síntesis de moléculas complejas en organismos a partir de otras más simples.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.
