,1. A urine sample with more than 100,000 organisms is considered indicative of
infection. A urine sample containing 5,000 bacteria, with a generation time of 30
minutes, sits for 3 hours before finally being assayed. How many bacteria will then be
present within the sample?

1. Studies done by Buchner showed that ground-up yeast cells were able to convert
sugar to alcohol. The components of the mixture that were responsible for the
chemical transformation were

1. If the processes of aerobic and anaerobic respiration are basically similar - differing
only in the terminal electron acceptor -why do they produce different amounts of
energy? They produce different amounts of energy because not all electrons are
brought into the electron transport chain with the same amounts of potential energy.
