Which nutrient is a key component in cell membranes neurons and certain hormones?
Phospholipids are the key component in cell membranes, while phosphorus is essential for neurons. Cholesterol is vital for the structure and function of cell membranes and is a precursor for certain hormones, such as steroid hormones.
What is used to store energy and make cell membranes and hormones?
Lipids are used to store energy in the form of triglycerides, make up cell membranes as phospholipids, and serve as precursors for the synthesis of hormones such as steroid hormones.
The compound that allows materials to move through cell membranes by osmosis is?
The compound that allows materials to move through cell membranes by osmosis is water. Water moves freely through cell membranes to maintain osmotic balance within the cell.
What are the functions that cell membranes perform?
Cell membranes perform several key functions, including acting as a barrier to regulate the passage of substances in and out of the cell, providing structural support to the cell, facilitating cell communication and signaling, and recognizing and binding to specific molecules like hormones or antigens.
What molecule stores energy and forms cell membrane and acts as hormones and insulates?
The molecule that fits this description is lipid. Lipids store energy, form cell membranes as phospholipids, act as hormones like steroid hormones, and provide insulation through substances like adipose tissue.

What cell part receives nerve impulses and hormones from other?
receptor molecules on cell membranes receptor molecules on cell membranes

Why can steroid and thyroid hormones but not amino acid-based hormones move across cell membranes?
Steroid and thyroid hormones are lipid soluble, allowing them to diffuse directly across cell membranes. Amino acid-based hormones are water soluble and require specific receptor-mediated mechanisms to enter cells.

Why is a second messenger not necessary in a steroid hormone?
Steroid hormones act in the transcriptional level in the nucleus of a cell, due to their ability to travel through cell membranes (hydrophillic). Second messengers are necessary for hormones that cannot penetrate cell membranes (peptides).
Hormones are classified into two main categories which are what and what?
Hormones are primarily classified into two main categories: steroid hormones and peptide (or protein) hormones. Steroid hormones, such as cortisol and estrogen, are derived from cholesterol and are lipid-soluble, allowing them to pass through cell membranes. Peptide hormones, like insulin and growth hormone, are composed of amino acids and are typically water-soluble, requiring receptors on the cell surface to exert their effects.
Passage of water through cell membranes?
Osmosis
What is the difference between protein hormones and steroid hormones and how they communicate with their target cells?
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
Can large hydrophobic molecules cross cell membranes?
Yes, large hydrophobic molecules can cross cell membranes through passive diffusion.
