protein
Passive transport is not an example of essential nutrients for the cell.
Why are proteins an essential nutrient to include in a balanced diet?
An indispensable nutrient is also known as an essential nutrient. About 40 nutrients are currently known to be essential for human beings.
An essential nutrient is a nutrient that the body needs to work properly, and which the body cannot generate on its own. Examples of essential nutrients include vitamins, minerals and some amino acids.
A substance is called a limiting nutrient when its availability restricts the growth and productivity of an organism or a population. This nutrient is essential for biological processes, but its scarcity hinders optimal growth and development.
Monosodium glutamate (MSG) is a common example of a chemical in food that is not a nutrient. It is often used as a flavor enhancer in certain foods but does not provide any nutritional value in terms of essential nutrients.
One example of a nutrient that contains nitrogen, carbon, hydrogen, and oxygen is amino acids. Amino acids are the building blocks of proteins and are essential for various biological functions in the body.
Essential nutrients cannot be made in the body.

Any nutrient that cannot be made by the body and must be supplied by food is called an "essential" nutrient. For example, humans cannot make Omega-3 fatty acids but they are necessary for life, so we call them an essential fatty acid.
