CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
(Accelerated only) During cell respiration, glucose is ____
A
reduced
B
oxidized
C
built and ends up with more energy
D
produced by photosynthesis
Explanation: 

Detailed explanation-1: -In cellular respiration, glucose is oxidized, and oxygen is reduced to form CO2 and water.

Detailed explanation-2: -Aerobic respiration is the process of complete oxidation of organic foods into carbon dioxide and water in presence of oxygen.

Detailed explanation-3: -There is one redox reaction during glycolysis. The oxidation of glucose begins during glycolysis. NAD+ accepts the electrons during the oxidation, and as a result it gets reduced. A total of 2 NADH are produced.

Detailed explanation-4: -(iii) In the process of glycolysis, glucose molecules are oxidised to produce the molecules of pyruvate.
