Alcoholic fermentation in yeast lab answers

29/03/2021 Client: saad24vbs Deadline: 2 Day

BIOL 102: Lab 7

Yeast Fermentation

PRE-LAB ASSIGNMENT:

Students are expected to read pages 1-2 before coming to the lab to complete the experiments.

Print this entire lab packet and bring it to the laboratory.

Please provide a FULL lab report for this experiment following the “Lab Report Guidelines”.

Please note that this lab report WILL include a HYPOTHESIS.

Objectives:

· Observe yeast fermentation

· Determine the optimum conditions for yeast fermentation

Background:

All fungi are eukaryotes. Although they vary in size and shape, fungi share key characteristics including their way of obtaining nutrients for growth and energy. Fungi are heterotrophs and they depend on preformed carbon molecules produced by other organisms. However, fungi do not ingest food and then digest it using enzymes; instead they invade -think of a moldy piece of bread-a food source and secrete digestive enzymes onto it. The digestion occurs outside the body. When the polymers are broken down into monomers, the fungi absorb the predigested food into its body.

Yeast are microscopic, unicellular organisms in the Kingdom Fungi. Like other fungi, yeast are incapable of making their own food, but like any other organism, need food for energy. They rely on carbohydrates (usually sugars) found in their environment to provide them with this energy so that they can grow and reproduce. There are many species of yeast, and each has a particular food source.

Regardless of the food source, yeast perform fermentation which does not utilize oxygen. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end, but no electron transport chain. Therefore, only 2 ATPs are formed per glucose.

Fermentation and cellular respiration begin the same way, with glycolysis. In fermentation, however, the pyruvate made in glycolysis is not completely oxidized because it does not continue through the citric acid cycle and the electron transport chain does not run. Because the electron transport chain is not functional, the NADH cannot drop its electrons off to the electron transport chain, and thus very few ATP molecules are synthesized because the ATP synthase is not running.

Based on the end products, fermentation can be of two types: ALCOHOLIC fermentation (the subject of this lab) and LACTIC ACID fermentation.

Regardless of the type of fermentation, the purpose of the extra reactions in fermentation, is to regenerate (recycle) the electron carrier NAD+ from the NADH produced in glycolysis. The extra reactions accomplish this by letting NADH drop its electrons off with an organic molecule such as acetaldehyde to produce ethanol (alcoholic fermentation), or pyruvate to produce lactic acid (lactic acid fermentation). This “drop-off” of electrons allows glycolysis to keep running by ensuring a steady supply of NAD+.

Going from pyruvate to ethanol is a two-step process. In the first step, a carboxyl group is removed from pyruvate and released as carbon dioxide, producing a two-carbon molecule called acetaldehyde. In the second step, NADH passes its electrons to acetaldehyde, regenerating NAD+ and forming ethanol.
