Chapter 3, Problem 3CT

Section 3.17 mentions that arsenic poisons human cells because it halts the production of ATP. This happens because the structure of arsenic atoms closely resembles that of phosphorus atoms—so close, in fact, that arsenic can take the place of phosphorus in chemical reactions. Why would the substitution of arsenic atoms for phosphorus atoms prevent the formation of ATP?

In biochemistry, what form of iron, ferric or ferrous, is most readily absorbed by the body? What does that information suggest about the dietary availability of iron in “aged” meat?
In living cells, glucose, a six-carbon molecule, is converted into two three-carbon molecules. What type of chemical reaction is this?
Despite the thermal stability of covalent bonds in physiological systems, some of these bonds are sensitive to energy input from external sources. The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. If the increase in energy is above kT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following physiological process is example to this? Select one : a. Absorbance of light by 11-cis-retinal. b. Translucent to opaque conversion of egg whites after cooking. C. Absorbance of light by melanın. d. a & b e. a & c f.b&c g. a, b & c
