Question

In cellular respiration, carbon dioxide is formed from the oxidation of the following:

Answer 1

Answer:

In cellular respiration, carbon dioxide is formed from the oxidation of glucose molecule.

Respiration is also called energy releasing process. In respiration, oxygen is inhaled through the air into the body which combines with glucose which is present inside the cells. This combination of oxygen and glucose produces carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). Carbondioxode removed from the body through lungs and ATP is used for different processes.

Answer 2

Answer: Though the options are not provided, in cellular respiration, carbon dioxide is formed from the oxidation glucose.

Explanation: In cellular respiration, glucose is broken down in the presence of oxygen to produce energy with the release of carbon dioxide and water as the by-products. The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy. Energy produced in cellular respiration is in form of ATP. Cellular respiration is made up of four stages: 1). glucose is oxidized in a series of ten enzyme catalyzed reactions to two molecules of pyruvate in a process known as glycolysis.

2). Each molecule of pyruvate is further oxidized to Acetyl CoA

3) Acetyl CoA enters the Krebs cycle in a series of either enzyme catalyzed reactions to generate ATP, FADH2 and NADH.

4) FADH2 and NADH enter the electron transport chain to be further oxidized to ATP.

The ATP is the form of usable energy in the cells and is used to drive other cellular functions.
