Explain what occurs during a nerve impulse. what is saltatory conduction\

1 answer:

8 0

During a nerve impulse, At the end of the axon from which the impulse is coming, the membrane depolarizes, gated ion channels open, and calcium ions (Ca2+) are allowed to enter the cell. When the calcium ions rush in, a chemical called a neurotransmitter is released into the synapse. The neurotransmitter binds with receptors on the neuron. A saltatory conduction is the propagation of action potentials along myelinated axons from one node of Ranvier to the next node, increasing the conduction velocity of action potentials.

Why is cytoplasmic streaming called "active mass movement of cytoplasm"? ...?

harkovskaia [24]

Hi , cytoplasmic streaming is actually circulating around in the cell . It moves and by doing do it can help move organelles and harmful/helpful chemicals to where they need to be in the cell , so that's why cytoplasmic streaming is also called active mass movement of cytoplasm.

which of the following Is not a cell activity powered by energy produced through cellular respiration? 1. Division 2. Growth 3.

Zarrin [17]

Of the options listed, we can confirm that passive transport is not a cellular activity that is powered by the energy received through cellular respiration.

Cellular respiration is a process that produces much of the energy needed and used by a cell. The production of this energy is in the form of a molecule known as ATP. This ATP molecule is responsible for powering the growth of cells by acting as the substrate for most of the metabolic reactions present, as well as powering cellular division and repair.

The only option listed that is not powered by the use of ATP generated through cellular respiration, or any other energy-generating method, is passive transport. In order to move substances in and out of a cell, transport methods are used. These methods can be:

Active transports
Passive transports

Active and passive transports differ in one specific way. Passive transports do not consume energy, whereas active transports do. Therefore, since passive transports use chemical gradients which are natural processes that do not use energy, it will have no need for the ATP of the cell, and therefore the correct answer is "4. Passive Transport"
