What biomolecule is responsible for waterproofing molecules?


Sharing is Caring


The most common type of lipid is triglycerides, which include fats from animals and oils from plants. Triglycerides generally serve as long-term energy storage molecules, except indigestible waxes, which are instead used as a waterproofing substance in both plants and animals.

Which elements are found in all biological macromolecules?

Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.

What element does carbon bond with to make up life’s molecules?

What elements does carbon bond with to make up life’s molecules? Carbon can bond w/ many elements, including hydrogen, oxygen, phosphorus, sulfur, carbon, and nitrogen to form molecules of life. Carbon has the ability to form millions of different large and complex structures.

What makes the cell membrane waterproof?

Cell membranes are waterproof due to the lipid portion of the membrane bilayer. Cell membranes are made of a phospholipid bilayer which has proteins within it. The phosphate groups form the polar heads of the membrane, while the lipids form the non polar tails.

What lipids make the cells waterproof?

All of the lipid molecules in cell membranes are amphipathic (or amphiphilic)โ€”that is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“water-fearing”) or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.

What is the most important biomolecule?

Proteins. Proteins are the primary building materials of the body. Your hair, skin, muscles, and organs are composed mostly of proteins. Proteins are strong yet flexible, and they have a complex 3-D structure.

Which of the four primary biological molecules is the most important for living processes?

Proteins. Proteins are the first of the molecules of life and they are really the building blocks of life. Proteins are the most common molecules found in cells.

What are membranes made of?

Membranes are composed of lipids, proteins and sugars This structure is generally referred to as the phospholipid bilayer. In addition to the various types of lipids that occur in biological membranes, membrane proteins and sugars are also key components of the structure.

What group of organic molecules function as carriers or channels within cell membranes make motion possible and help to defend the body against disease?

What group of organic molecules function as carriers or channels within the cell membrane, make motion possible and help defend the body against disease? a high energy storage molecule. What bonds hold the secondary structure of protein in place?

Which type of macromolecule has the function of storing and transmitting hereditary or genetic information?

Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. This information is encoded in the sequences of monomers that make up nucleic acids. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Which classes of macromolecules have a significant role in energy storage select all that apply?

While carbohydrates supply immediate energy for the body, lipids โ€” a class of macromolecule โ€” provide long-term energy storage.

What property properties of carbon makes it essential for organic life select all that are correct )?

Organic Compounds Carbon has the ability to form very long chains of interconnecting C-C bonds. This property allows carbon to form the backbone of organic compounds, carbon-containing compounds, which are the basis of all known organic life.

How is the number of bonds carbon can make related to its ability to form molecules with many different shapes?

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

What are atoms that vary in the number of neutrons found in their nuclei called?

Atoms of the same element that differ in their numbers of neutrons are called isotopes.

What to the membrane which covers the cell?

Definition. The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface.

What part of the membrane protein is hydrophobic?

The portions of an integral membrane protein found inside the membrane are hydrophobic, while those that are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic.

Why is part of the cell membrane hydrophobic?

In contrast, the interior of the membrane, between its two surfaces, is a hydrophobic (“water-hating”) or nonpolar region because of the fatty acid tails. This region has no attraction for water or other polar molecules (we will discuss this further in the next page).

What is called cell membrane?

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Why are lipids waterproof?

Lipids are non-polar molecules, so they are not soluble in polar solvents like water. If you’ve ever tried to combine oil and water, you’ve seen how poorly they mix. This feature of lipids allows our bodies to use them as waterproof barriers and as biological membranes.

What part of the plasma membrane is hydrophobic quizlet?

The portion of the bilayer that is hydrophobic is the phospholipid of the cell membrane tails.

Are lipids a biomolecule?

Fats and oils are part of a class of biomolecules called lipids, which are loosely defined as biomolecules that are insoluble in water but soluble in organic solvents like hexane or chloroform.

Why is lipid The most important biomolecule?

Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.

What are important biomolecules in the body?

Biomolecules are important for the functioning of living organisms. Several macromolecules (protein, carbohydrates, nucleic acids, and enzymes) and small molecules (amino acids, vitamins, fatty acids, neurotransmitters, and hormones) fall under the category of biomolecules.

Which two substances are among the four major types of organic compounds made by living things apex?

  • Carbohydrates. Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen atoms in a 1-2-1 ratio.
  • Lipids. Lipids consist of compounds such as fats, oils and waxes.
  • Nucleic Acids.
  • Proteins.

What are the four types of biological molecules describe their basic structures and functions?

biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
