Which macromolecule do we get from our parents and not our food?
Nucleic acids, and DNA in particular, are key macromolecules for the continuity of life. DNA bears the hereditary information that’s passed on from parents to children, providing instructions for how (and when) to make the many proteins needed to build and maintain functioning cells, tissues, and organisms.

Glucose does not contain amino acids whereas proteins contain amino acids. Thus, the energy provider is not a function of proteins. Hence, the correct option is the option (D) As energy provider for metabolism.
Do we get nucleic acids from food?
Most natural foods which contain resting cell tissue, such as grains of seed, have only high-molecular- mass nucleic acid components with different concentrations; however, growing cell tissue (e.g. soya-bean sprouts) show, as well as the nucleic acids, some lower-molecular-mass compounds.
What is blank food?
“Empty” literally means “ containing nothing .” When it comes to food, empty means that that food contains little or no essential vitamins or minerals. In other words, these foods provide nothing of value to your body beyond calories that create excess pounds.

What macromolecule is chicken?
Chicken is a form of complete protein , providing you with all of the essential amino acids your body needs to make new proteins.
Is protein A macromolecule?
Proteins. After nucleic acids, proteins are the most important macromolecules . Structurally, proteins are the most complex macromolecules.
Which of the following is not a macromolecule or polymer?
Lipids are the only macromolecules that are not polymers. Lipids are diverse in structure and function, but all have in common that they are hydrophobic—that is, they are nonpolar and do not dissolve in water.
Is RNA a macromolecule?
Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”.
Is insulin a macromolecule?
Insulin is a protein composed of two chains, an A chain (with 21 amino acids) and a B chain (with 30 amino acids), which are linked together by sulfur atoms. Insulin is derived from a 74-amino-acid prohormone molecule called proinsulin.
Which biomolecules are not found in food?
Ernest Z. Nucleic acids are not considered nutrients. There are thousands of different types of molecules in a cell, but there are only four major classes of biomolecules. These are carbohydrates, lipids, proteins, and nucleic acids.
