Question

Breaking down of glucose in the presence of oxygen produces

(A)Carbon dioxide

(B)water

(C)energy

(D)all of the above​

Answer 1

Answer:

In the presence of oxygen- When breakdown of glucose is carried out in the presence of oxygen in a cell, it is called as aerobic respiration. Glucose is converted into a 3 carbon molecule called pyruvate which further breaks down in the presence of oxygen to form carbon dioxide and water.

Answer 2

Answer:

The breaking down of glucose in the presence of oxygen produces carbon dioxide, water, and energy. So the best option is (D)all of the above​

Explanation

• When glucose breaks down in the presence of oxygen it will produce all carbon dioxide, water, and energy (ATP) through Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation.
• During this reaction, it will produce reducing equivalents NADH, NADPH, and FADH. These reducing equivalents enter into the electron transport chain to produce ATP and water.
• From one glucose breaks down into two pyruvates and 32 ATP molecules.
