What is common among DNA protein and fats?
What is common among DNA, proteins and fats? All contain acids.
Which best describes starches and lipids?
Q. Which best describes starches and lipids? Starches and lipids provide the cell with energy.
Which statement about simple sugars and amino acids is correct?
Which statement concerning simple sugars and amino acids is correct? They are both needed for synthesis of larger molecules.
What molecules are assembled from smaller organic compounds?
The smaller molecules act as building blocks and are called monomers, and the macromolecules that result from their linkage are called polymers. Cells and cell structures include four main groups of carbon-containing macromolecules: polysaccharides, proteins, lipids, and nucleic acids.
Which best describes the relationship between DNA and proteins?
DNA is made up of proteins, which tell a cell how to function. Proteins are made up of DNA, which determines the cells that are produced. Cells contain DNA, which controls the production of proteins. Which part of the DNA molecule determines an organism’s traits?
Which is true about the structure of starches and proteins?
Which is true about the structure of starch molecules and protein molecules? A. Starches and proteins are both polymers. … Starches and proteins are both built from nucleic acids.
Which statement describes the formation of a protein molecule?
Which statement describes the formation of a protein molecule? Amino acids combine to form a protein chain. Which two students correctly described organic compounds? Lipids use the relatively high energy contained in carbon-hydrogen bonds to perform their primary function.
What do proteins starch and DNA have in common?
Indeed, proteins, starch and DNA are all considered to be organic compounds. Organic compounds are molecules that contain carbon in them, oftentimes containing hydrogen and oxygen. All of the compounds listed above contain carbon and are therefore organic.
Which statement best describes sugar and fat molecules?
Which statement best describes these two molecules? Sugar molecules are organic and fat molecules are inorganic. Energy for life processes can be stored within the chemical bonds of both molecules.
What statement describes proteins?
A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.
Which statement best describes protein molecules in a cell?
Which statement best describes some protein molecules in a cell? Proteins are long, folded chains that can form various cell parts. Proteins are composed of four different starches that direct cell activity.
Which statement describes the monomer of proteins?
Explanation: A monomer is a single molecule that can be joined together with other same molecules to form a polymer. The building blocks of proteins are amino acids, which contain elements such as H,N,O,C , and more. They are the monomers of the proteins.
What is protein PDF?
Proteins are made up of hundreds or thousands of smaller units known as amino acids. There are 20 different kinds of amino acids that are linked together by peptide bond to make a protein molecule. … Proteins are not entirely rigid molecules. They undergo conformational changes upon ligand binding.
What’s a DNA molecule?
DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Which statements describe the relationship between genes and DNA?
The correct answer is a) genes, the basic unit of heredity, are located on chromosomes, which consist of strands of DNA.
What is protein Slideshare?
PROTEINS • The Molecules which yields amino acids upon hydrolysis are called proteins. • Proteins are natural polymer of amino acids. • The number of amino acids in a protein molecule may range from two to several thousands. • Protein molecules contain Nitrogen, Carbon, Hydrogen and Oxygen. Prepared by: Sidra Javed.
How proteins are metabolized?
Protein metabolism occurs in liver, specifically, the deamination of amino acids, urea formation for removal of ammonia, plasma protein synthesis, and in the interconversions between amino acids.
What are proteins introduction?
Protein is a chemical compound that contains the same atoms as carbohydrate and fat – carbon (C), hydrogen (H) and oxygen (O) – but protein also contains nitrogen (N) atoms. These C, H, O and N atoms are arranged into amino acids, which are linked into chains to form proteins.
