Are fats used as parts of biological membranes?
Proteins are a major constituent of biomembranes, accounting for as much as 50% of the volume. The primary molecules found in biological membranes around cells are lipids (biological fat or wax molecules).
What 3 things is nucleotide made of?
A Nucleotide are molecules that when combined make the structural units of DNA and RNA. An actual nucleotide is made up of small components. These components are; Phosphates Sugar Heterocyclic Base
What are four major biomolecules and what are their functions?
1. nucleic acids: Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These molecules carry genetic information or form structures within the cells. 2. Proteins: alcohol dehydrogenase (an enzyme), and actin & myosin (structural proteins). Enzymes catalyze biochemical reactions in the body, while some proteins have structural or mechanical functions, such as actin and myosin in muscles. 3. carbohydrates: glycogen (storage of energy) and cartilidge in animals (structural components). 4. lipids: structural components of cell membranes, energy storage sources and intermediates in signaling pathways. Cholesterol, Vitamins A, D, E and K. BKM :)
What is most likely to occur if the sugar molecules can cross the membranes?
Sugar molecules move outside of the membrane.
What are the two types of molecules that compose cellular membranes?
Lipids and Proteins
Which of the fowllowing is not true of lipids?
Lipids have various functions within the body. They store energy, act as the structural components of cell membranes, and act as signaling molecules.
What molecules have hydrophobic and hydrophillc components?
all animal cell membranes
Why is cholesterol so important to the plasma membrane?
why are cholesterol molecules important components of cell membranes
What good are polysaccharide?
In animals, they are primarily energy storage molecules, although there are a lot of polysaccharide chains that do many extremely important jobs on the membranes of body cells. In plants, they are not only very important food storage molecules (starch), they also serve as structural materials (cellulose) and components in wood.

What is the Main structural component of a plasma membrane?
The basic structure of all membranes is the same. They are composed of two layers of phospholipid molecules, associated with other molecules including proteins, carbohydrates and cholesterol. I hope this helps.

A Nucleotide are molecules that when combined make the structural units of DNA and RNA. An actual nucleotide is made up of small components. These components are; Phosphates Sugar Heterocyclic Base
What cell part receives nerve impulses and hormones from other?
receptor molecules on cell membranes receptor molecules on cell membranes
Lipids are called the “workers of the cell?
yes lipids are workers of the cell because The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. ... Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterol-containing metabolites such as cholesterol.
Does plasma membranes have molecules on their surface that identifies them?
No
Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
What are proteins found in cell membranes that transport large molecules?
carrier molecules
