Chapter 4, Problem 5CT
Summary Introduction
To explain: What gas will form when catalase combines two hydrogen peroxide molecules to make two molecules of water.
Concept introduction: Catalase is an enzyme of peroxisomes that has four tightly bound cofactors called hemes. A heme is a small organic compound with an iron atom at its center. Catalase substrate is hydrogen peroxide (H2O2) formed during normal

Soy sauce is made by fermenting a salty combination of soybeans and wheat for 8 to 12 months with a variety of microorganisms, including yeast. After the particles are removed, the resultant sauce is high in lactate and ethanol. What is the process for making these two compounds? To avoid a pronounced vinegary flavor in the soy sauce, air must be kept out of the fermenting tank (vinegar is dilute acetic acid). Why?
In the following chemical reaction, which compounds are the products? Carbon dioxide + Water - Sugar + Oxygen

- The 2-carbon alcohol called ethanol is most common because it's made from something else very common: sugar! (this is also why ethanol is the one alcohol that's not toxic, our bodies can metabolize it). Ethanol is mass-produced in factories on an industrial scale, and is commonly used as a fuel (or mixed as an additive into other fuels). The combustion reaction below shows that 6 molecules of oxygen is required to completely burn two molecules of ethanol.
