Exam 2: A: The Chemical Basis of Life

Electrolytes include acids,bases,and salts.

Both phospholipids and steroids are found in cell membranes.

Steroids are the only lipid that contains a ring structure.

The quaternary structure of a protein contains more than one polypeptide chain.

The distance between the sugar-phosphate structures in a DNA molecule is equal to the distance of one purine and one pyrimidine molecule.

The digestion of food is an example of a decomposition reaction.

When two amino acids are joined,a peptide bond is formed and an H⁺ ion is released.

Hydrogen will react with other atoms to get 8 electrons in its outer energy level.

According to the general formula,in synthesis reactions,the number of reactants is usually greater than the number of products.

Glycoproteins contain both a fat molecule and a protein molecule.

Catabolism and anabolism are major types of metabolic activity.

Prostaglandins are associated with the prostate gland and therefore are not found in women.

A sucrose molecule is formed by the synthesis reaction between glucose and fructose.

By definition,inorganic compounds do not contain carbon.

In a formula for a chemical reaction,the substances on the right of the arrow are referred to as products.

A solution containing the same number of H⁺ ions and OH- ions would have a pH of zero.
