Question

cellular respiration occurs in which three stages? light reaction, dark reaction, atp production glycolysis, krebs cycle, electron transport aerobic, mitochondria, atp production dark reaction, light reaction, dna production

Answer 1

The 3 stages of cellular respiration include Glycolysis, the Citric Acid or the Krebs Cycle, and the Electron Transport Chain.

Answer 2

The correct answer would be glycolysis, Krebs cycle, electron transport.

Cellular respiration refers to the set of the chemical reaction taking place in a cell in order to convert the chemical energy of the food into adenosine triphosphate (ATP).

These chemical reactions can be majorly divided into three stages:

1. Glycolysis: It takes place in the cytoplasm of the cell. It converts one molecule of glucose (6C) into two molecules of pyruvate (3C) with a net gain of 2 ATP molecules and 2 NADH molecules.

The pyruvate is then transported into the mitochondria where rest of the reactions take place.

2. The pyruvate is converted into acetyl Co-A which then enters the Krebs cycle. The cycle undergoes two round to utilize 2 acetyl Co-A and produces 4 CO₂. It also produces 6 NADH, 2 FADH₂, and 2 ATP.

3 All the NADH and FADH₂ produced undergo electron transport chain and produces ATP with the help of oxidative phosphorylation.
