Two macromolecules that provide support to a cell are collagen and cellulose. Collagen is a protein found in the extracellular matrix of animal cells, giving structural strength and support to tissues. Cellulose, a carbohydrate, is a key component of the plant cell wall, providing rigidity and protection. Both macromolecules play crucial roles in maintaining the integrity and shape of cells in their respective organisms.

What cell in the human nervous system whose primary function is to provide insulation and structure for neurons on which they may develop and work?

The cells in the human nervous system that provide insulation and structure for neurons are called glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. These cells produce myelin, a fatty substance that wraps around the axons of neurons to insulate and support their function by speeding up the transmission of nerve impulses.


What is real value?

a function whose range is in the real number


What is path function in thermodynamics?

A path function in thermodynamics is a function whose value depends on the path taken to reach a particular state. Examples include work and heat. These functions are not solely determined by the initial and final states but also by the process followed.


A neurotransmitter whose function depends on a second messenger is known as?

A neurotransmitter whose function depends on a second messenger is known as a neuromodulator. Neuromodulators can influence the behavior of neurons by affecting processes like signal transduction or synaptic transmission.


What would you expect to find in cells whose main function is absorption?

Cells whose main function is absorption would typically have a large surface area, such as microvilli or brush border, to increase their ability to absorb nutrients or substances. Additionally, these cells may have specific transport proteins and channels to facilitate the movement of molecules into the cell. They may also contain high concentrations of mitochondria to provide energy for the absorption process.
