Isotopes & Radioactive Decay. Includes using relationships between half-life (t1/2), decay constant, understanding decay.

The isotope C14 has a half-life of 5700 years. What fraction of the C14 atoms will decay (a) each year, and (b) each minute?

Isotopes and Radioactive Decay. Calculate the total radioactivity that results from one isotope in the human body. Must understand the concepts of half-life, decay constant, DPM, decay.

K40 (half-life=1.3x10E9 years) composes approximately 0.012% of the potassium found in nature. By weight, the human body is approximately 0.35% potassium. Calculate the total radioactivity that results from K40 decay in a 75 kg human.

Understanding molecular behaviour.

Are the following statements true or false? If false, explain why. a) In most globular proteins, the nonpolar amino acids tend to be concentrated at the surface of the protein. b) A small organic molecule required by an enzyme in order for the enzyme to be a functional catalyst is known as a vitamin. c) Lipids that are solids at room temperature tend to have more double bonds than liquids at room temperature.
