Called the power plants of the cell the mitochondria contain two highly specialized membranes an outer membrane and a highly folded inner membrane that separate two compartments the internal matrix space and the narrow intermembrane space. Which of the following treatments is least likely to denature the proteins in a food.

When many amino acids are joined together the result is called a polypeptide or a protein.
A polypeptide must contain at least how many amino acids. In a polypeptide of 9 amino acids there are 8 peptide bonds between them. Supplies all of the essential amino acids in amounts needed by the body. A human cell contains about 2000 of these.
A polypeptide is a long continuous and unbranched peptide chain. Hemoglobin is composed of four monomers. A protein consists of one or more polypeptides more than about 50 amino acids long.
An oligopeptide consists of only a few amino acids between two and twenty. Peptides are distinguished from proteins on the basis of size and as an arbitrary benchmark can be understood to contain approximately 50 or fewer amino acids. There are two a chains each with 141 amino acids and two b chains each with 146 amino acids.
Because there are two different subunits hemoglobin exhibits heteroquaternary structure. The number of water molecules required is equal to the number of peptide bonds that need to be broken. Any chain of two or more amino acids is called a peptide.
A polypeptide must contain at least how many amino acids. If all of the monomers in a protein are identical there is homoquaternary structure. A polypeptide is a single linear chain of many amino acids any length held together by amide bonds.
Which of the following foods is the best protein. Acidity alkalinity heat alcohol oxidation and agitation freezing.
