Recent experiments in a lab have focused on trying to understand cellular mechanisms that underlie epilepsy. Many of the studies involve recording electrical activity in neurons from brains of adult fruit flies (Drosophila). Brains in all animals are made up of a collection of highly specialized cells surrounded by fluid. […]

Flask A contains yeast cells in glucose-minimal salts broth incubated at 30C with aeration. Flask B contains yeast cells in a glucose-minimal salt broth incubated at 30C in an anaerobic jar. -Which culture produced more ATP?-Which culture had a shorter generation time?-which culture had a greater cell mass?-which culture produced […]

A “pulse-chase” experiment using 14C -labeled carbon sources is carried out on a yeast extract maintained under strictly anaerobic conditions to produce ethanol. In this experiment, a small amount of 14C -labeled glucose is incubated with the yeast just long enough for each intermediate molecule in the glycolysis pathway to […]
