The reason for which a heterotrophic organism needs vitamins, whereas autotrophs do not. Concept introduction: According to the nature of food creation and consumption, the organisms are basically classified into two groups, such as autotrophs and heterotrophs. The autotrophs are the organisms that can synthesize their own food from simple molecules using water, carbon dioxide in the presence of sunlight, and chlorophyll. The heterotrophic organisms are unable to synthesize their own food and depend on other living organisms to obtain food.

Expert Solution & Answer

Explanation of Solution

Explanation:

Autotrophs possess the capability of synthesizing micronutrients including vitamins and minerals. They can synthesize all the nutrient molecules they require, whereas heterotrophs cannot synthesize these micronutrients and depend on their food intake for supply of these important nutrients. Hence, heterotrophic organisms require vitamins in their nutrition, whereas autotrophs do not.

How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
