Which of the following statements is true of chemoautotrophs? O They use hydrogen sulfide as their hydrogen source for the photosynthesis of their organic compounds. O They "feed themselves" by obtaining energy from the chemical bonds of organic molecules. O They oxidize inorganic compounds to obtain energy to drive the synthesis of their organic compounds. O They live as decomposers of inorganic chemicals in organic litter. O They obtain their energy from oxidizing chemical compounds and get their carbon skeletons from organic compounds.

Yeast cells are added to sterilized corn mash in large industrial fermenters to produce ethanol, which is added to gasoline. It is necessary to install cooling systems around the fermenters because       heat is released at each step of the fermentation pathway   heat is absorbed by yeast as they carry on fermentation   cooler temperatures decrease the production of the CO2 by-product   ethanol is less toxic to yeast at cooler temperatures

There are two regulators in the Principles of Bioenergetics. They are:   Group of answer choices ATP utilization rate and proton conductance ADP use and CO2 production Carbon and NAD

A new enzyme (protein) that helps protect a bacterial cell from reactive oxygen species (causing oxidative stress) has been discovered. It can be expected that the gene that codes for this enzyme will be expressed in phase of growth. order to make the enzyme in the lag Not very likely. They just got transferred to fresh new medium, how much stress can they be under? O stationary O late log O log
