Please mark my multiple choice paper: Mark the INCORRECT alternative concerning the Introduction to Biochemistry: B) To learn the main chemical elements of the human body. To learn only the structures of atoms, but not of ions and molecules. To learn the properties of acids, bases and mineral salts and inorganic and organic salts. To learn the constituent units and functions of carbohydrates, lipids and proteins.   2. Concerning the Chemical bonds. Choose the INCORRECT alternative: C) The forces that hold together the atoms of a molecule or a compound are Chemical bonds. The likelihood that an atom will form a chemical bond with another atom depends on the number of electrons in its outermost shell, also called the valence shell. An atom with a valence shell holding eight electrons is chemically stable, which means it is likely to form Chemical bonds with other atoms. All the previous alternatives are incorrect.   3. Chemistry is the science of the structure and interactions of…

Many kinds of biomolecules are made of smaller monomers that are put together in different sequences. a good example is carbohydrates. polysaccharides is formed by combining monosaccharides. when to monosaccharides combine together, a disaccharide is formed. when more than three monosaccharides combine, a polysaccharide is formed.    essay question: What process results in the formation of polysaccharides from monosaccharides? Condensation or hydrolysis. Explain your answer by giving examples. Show the chemical reaction taking place.

Mass spectrometry and X-ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to mass spectrometry, X-ray diffraction, or both techniques. Mass spectrometry protein must be conformationally stable X-ray diffraction small amounts of protein are sufficient analysis requires information about the protein-coding gene or genes Answer Bank protein may be denatured requires a large amount of protein protein sample must be pure can detect a covalent modification to a protein Both techniques

CALCULATOR COLOR THEME Q Q ZOOM 3. The 1952 Miller-Urey experiment involved heating water, methane, ammonia, and hydrogen in sealed, interconnected glass vials. The purpose of this experiment was to simulate the conditions and substances on early Earth before life. Heating these simple substances led to the formation of 23 simple amino acids in one week. Amino acids can be linked together into long, complex molecules that cells need to carry out the basic life functions. What can be determined by analyzing the data produced by the Miller-Urey experiment?
