<h3>What is photosynthesis?</h3>

Plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar in a process known as photosynthesis.

When performing photosynthesis, plants utilize the ambient carbon dioxide and release the oxygen gas they create into the atmosphere. Gas exchange is the term for this. Stomata, a unique part of the plant's leaf, are used to accomplish this. The guard cells that surround the stomata become turgid or flaccid in response to the entry or escape of water molecules, respectively. Stomata open and gas exchange occurs when the guard cells become turgid, or the other way around.

When neurons "fire," the first thing that happens is that sodium ions enter the cell. this does not require an input of energy.
Karo-lina-s [1.5K]

Answer;

One can infer that membrane transport proteins are required in order for neurons to fire.

Explanation;

Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.

-Transport proteins transport materials such as; ions such as sodium and potassium; sugars such as glucose; proteins and messenger molecules; and many more. In neurons, they  play a fundamental role in the functioning of nerve cells. These transporters, a third class of membrane transport proteins, move a wide variety of ions and molecules across cell membranes.
