Under anaerobic conditions, some organisms convert pyruvate into ethanol through a two-step enzymatic pathway. In the first step, pyruvate decarboxylase, an enzyme requiring thiamine pyrophosphate (TPP) and Mg²⁺, catalyzes the decarboxylation of pyruvate to acetaldehyde, releasing CO₂. In the second step, alcohol dehydrogenase reduces acetaldehyde to ethanol, using NADH as a reducing agent, which is oxidized to NAD⁺. This regeneration of NAD⁺ is essential for maintaining glycolytic flux under oxygen-limited conditions. The overall process allows for the recycling of NAD⁺ required by glyceraldehyde 3-phosphate dehydrogenase in glycolysis, thereby enabling continued ATP production in the absence of oxygen. This pathway is most commonly observed in yeast and some facultative anaerobes. If a yeast strain is genetically modified to lack functional pyruvate decarboxylase, which of the following outcomes is most likely?

A computer system carries out tasks submitted by two users. Time is divided into slots. A slot can be idle, with probability PI = 1/3, and busy with probability PB = 2/3. During a busy slot, there is probability P1/B = 1/4 (respectively, P2/B = 3/4) that a task from user 1 (respectively, 2) is executed. We assume that events related to different slots are independent. Choose , which is the probability that a task from user 1 is executed for the first time during the 5th slot. Choose , which is the expected number of slots up to and including the 5th task from user 1.
