Question

1. Compare and contrast aerobic respiration and fermentation. Focus on the carbon-containing products of these processes, relative oxidation states of these products, where energy stored in glucose is ultimately transferred, and which produces more ATP.

2. Draw the following. You may draw on a physical sheet, take a screenshot of the same, and upload it in the space below.

Diagram the electron transport chain. In your diagram include complexes I – IV, cytochrome C (Cyt C), coenzyme Q (Q), and ATP synthase. Identify and label components that are directly reduced by NADH and FADH₂, provide the name of the membrane the ETC is embedded in, and provide the names of the spaces inside and outside this membrane.

Answer 1

Ans.1 Following table shows the comparison between aerobic respiration and fermentation process:

Aerobic Respiration	Fermentation
It requires oxygen for carrying out the process	It does not require oxygen to complete the process.
Cytoplasm and mitochondria is the site where it occurs.	It occurs in the cytoplasm only.
Carbon Dioxide and Water are the end products.	Ethyl alcohol and Carbon Dioxide are the end products.
The respiratory substrate undergoes complete oxidation.	Respiratory substrate undergoes incomplete oxidation.
It consists of 3 steps;glycolysis,kerbs cycle and terminal oxidation.	It consists of only 2 steps;glycolysis and incomplete breakdown of pyruvic acid.
The energy produced is high,which is usually around 32-34 ATP per glucose molecule.	The energy produced is very less,which is 2 ATP molecules per glucose molecule.
