1. Explain the difference between fermentation and aerobic respiration. Fermentation is a partial degradation of sugars or other organic fuel that occurs without the use of oxygen. Aerobic respiration consumes oxygen as a reactant along with the organic fuel. 2. Summarize the catabolic degradation of food by aerobic respiration in words (rather ...
Explain the difference between fermentation and cellular respiration.
12 Ιουλ 2023 · Organisms break down organic molecules, such as glucose, through the common processes of cellular respiration and fermentation (Figure 1). Cellular respiration is generally described as an aerobic process, requiring oxygen, which yields the most possible ATP generated from one molecule of glucose.
Key Concepts-1. In plants and yeasts (fungi), the process of fermentation produces ethanol (alcohol) and carbon dioxide. Key Concept-2. In bacteria and animal cells, the products of glycolysis undergo fermentation in the cytoplasm to produce lactic acid when the oxygen level is low.
Fermentation is another process that oxidizes glucose. So how does fermentation differ from cellular respiration? Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste.
Upon completion of this topic you should be able to describe: the role of glucose and ATP in the powering of cellular reactions. the different types of fermentation in metabolism. the products of fermentation in yeast. how different sugars, temperature, and pH affect the rate of fermentation.
The main function of fermentation is to remove electrons from molecules of NADH, the energy-carrier produced by glycolysis, to form NAD+. The molecules of NAD+ are recycled to glycolysis, which can continue to produce a small amount of ATP without oxygen. There are two main types of fermentation.
