Answer: D. ethyl alcohol fermentation and the Krebs cycle
Fermentation is a process from which we can make ethanol. Fruits, grains tubers have been fermented to alcoholic beverages for ages. The process depends upon microorganisms called yeasts which produce enzymes that catalyze the conversion of glucose to ethanol and carbon dioxide
Yeast is used to breakdown complex carbohydrates to simple sugars. Biochemical process where glucose is converted to ethanol and carbon dioxide by the reaction of enzymes produced by yeast
The kerbs cycle which is also known as the citric acid cycle. The process takes place in the living cells within the mitochondria and consumes oxygen whilst producing carbon dioxide as a waste product
The processes that produces carbon dioxide as a waste product are ethyl alcohol fermentation and the Krebs cycle.
Further Explanation:
Respiration is the process of step wise oxidation of substrate molecules such as carbohydrates, proteins, fats and organic acids.
In plants there occurs two types of respiration, they are as follows:
1. Aerobic respiration: The type of respiration in which oxygen molecules are required.
2. Anaerobic respiration: The type of respiration in which oxygen molecules are not required.
The basic requirements for the occurrence of respiration:
1. Occurrence of glycolysis.
2. Occurrence of fermentation process in case of anaerobic respiration and Krebs cycle in case of aerobic respiration.
Glycolysis process:
It is the stepwise process wherein the glucose molecules breaks down into pyruvate molecules. It occurs in case of aerobic as well as anaerobic process.
Aerobic respiration:
The glycolysis is followed by occurrence of Krebs cycle in this type of respiration. Krebs cycle leads to release of carbon dioxide, NADH, [tex]\text{FADH}_{2}[/tex] and GTP molecules.
Anaerobic respiration:
The glycolysis is followed by fermentation process. There are two main types of fermentation, alcoholic fermentation and lactic acid fermentation.
Ethanol and carbon dioxide are produced during alcoholic fermentation in anaerobic respiration.
The lactic acid fermentation leads to production of lactic acid molecules, carbon dioxide is not produced during this process.
The electron transport chain is the series of complexes which transfers electron from an electron donor to its acceptor. It occurs in mitochondria
